VS项目，在生成的时候自动修改版本号

本文链接：https://blog.youkuaiyun.com/magicchz/article/details/143370421

demo示例：https://gitee.com/chenheze90/L28_AutoVSversion
可通过下载demo运行即可。
原理：通过csproject项目文件中的Target标签，实现在项目编译之前对项目版本号进行修改，避免手动修改；

1.基础版

效果图如下
在这里插入图片描述

部分脚本如下：

<Project>
<PropertyGroup>
    <PreBuildEvent>
    </PreBuildEvent>
  </PropertyGroup>
  <Target Name="SetAssemblyVersion" BeforeTargets="BeforeBuild">
    <PropertyGroup>
      <Year>$([System.DateTime]::Now.ToString("yy"))</Year>
      <MonthDay>$([System.DateTime]::Now.ToString("MMdd"))</MonthDay>
    </PropertyGroup>
    <Message Text="Setting AssemblyVersion to 01.00.00$(Year).$(MonthDay)" Importance="high" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//using System.Reflection;" Overwrite="true" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTitle(&quot;KR2-COMMON-MINI&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyDescription(&quot;科瑞2代MINI设备&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyConfiguration(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCompany(&quot;COM&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyProduct(&quot;COM_MES&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCopyright(&quot;Copyright @ COM&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTrademark(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCulture(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Runtime.InteropServices.ComVisible(false)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//[assembly: System.Windows.ThemeInfo(System.Windows.ResourceDictionaryLocation.None, System.Windows.ResourceDictionaryLocation.SourceAssembly)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyVersion(&quot;01.00.00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyFileVersion(&quot;01.00.00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyInformationalVersion(&quot;01.00.00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
  </Target>
</Project>

2.进阶版

部分项目要自定义生成版本号，可通过自定义类的方式来实现。
1.新建项目ClassLibrary1
2.引用系统类库sing Microsoft.Build.Framework;；using Microsoft.Build.Utilities;
3.新建类GenerateVersionTask

public class GenerateVersionTask : Task
    {
        [Output]
        public int Version { get; set; }

        public override bool Execute()
        {
            // 生成版本号的逻辑
            Version = GetVisitCount();
            return true;
        }
        private const string DataFilePath = "visit_counter.dat";

        public static int GetVisitCount()
        {
            // 读取存储的数据
            int visitCount = 0; DateTime lastVisitDate = DateTime.Now;
            ReadData(ref visitCount, ref lastVisitDate);

            // 获取当前日期
            DateTime today = DateTime.Today;

            // 检查是否是新的一天
            if (lastVisitDate < today)
            {
                // 重置访问次数
                visitCount = 0;
                lastVisitDate = today;
            }

            // 增加访问次数
            visitCount++;

            // 保存数据
            SaveData(visitCount, lastVisitDate);

            // 返回访问次数
            return visitCount;
        }

        private static void ReadData(ref int count, ref DateTime countdate)
        {
            if (File.Exists(DataFilePath))
            {
                string[] lines = File.ReadAllLines(DataFilePath);
                if (lines.Length == 2)
                {
                    int visitCount = int.Parse(lines[0]);
                    DateTime lastVisitDate = DateTime.Parse(lines[1]);
                    count = visitCount; countdate = lastVisitDate;
                }
            }
            else
            {
                File.Create(DataFilePath);
                count = 0; countdate = DateTime.Now;
            }
        }

        private static void SaveData(int visitCount, DateTime lastVisitDate)
        {
            string[] lines = { visitCount.ToString(), lastVisitDate.ToString() };
            File.WriteAllLines(DataFilePath, lines);
        }
    }

3.增加脚本

<UsingTask TaskName="GenerateVersionTask" AssemblyFile="$(TargetDir)\ClassLibrary1.dll" />

和

    <GenerateVersionTask>
      <Output TaskParameter="Version" PropertyName="MyVersion" />
    </GenerateVersionTask>

效果如图所示

  <UsingTask TaskName="GenerateVersionTask" AssemblyFile="$(TargetDir)\ClassLibrary1.dll" />
  <Target Name="SetAssemblyVersion" BeforeTargets="BeforeBuild">
    <PropertyGroup>
      <Year>$([System.DateTime]::Now.ToString("yy"))</Year>
      <MonthDay>$([System.DateTime]::Now.ToString("MMdd"))</MonthDay>
    </PropertyGroup>
    <GenerateVersionTask>
      <Output TaskParameter="Version" PropertyName="MyVersion" />
    </GenerateVersionTask>
    <Message Text="Generated Version: $(MyVersion)" Importance="high" />
    <Message Text="Setting AssemblyVersion to 01.0$(MyVersion).00$(Year).$(MonthDay)" Importance="high" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//using System.Reflection;" Overwrite="true" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTitle(&quot;MyAPPTitle&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyDescription(&quot;2021.03.29&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyConfiguration(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCompany(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyProduct(&quot;MyPro&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCopyright(&quot;Copyright ?  CCC&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTrademark(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCulture(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Runtime.InteropServices.ComVisible(false)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Windows.ThemeInfo(System.Windows.ResourceDictionaryLocation.None, System.Windows.ResourceDictionaryLocation.SourceAssembly)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyVersion(&quot;01.0$(MyVersion).00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyFileVersion(&quot;01.0$(MyVersion).00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyInformationalVersion(&quot;01.0$(MyVersion).00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
  </Target>
</Project>

4.自动写Alpha和Beta版本号

<Target Name="SetAssemblyVersion" BeforeTargets="BeforeBuild">
    <PropertyGroup>
      <Year>$([System.DateTime]::Now.ToString("yy"))</Year>
      <MonthDay>$([System.DateTime]::Now.ToString("MMdd"))</MonthDay>
    </PropertyGroup>
	<Exec Command="cmd /c git rev-parse --abbrev-ref HEAD" ConsoleToMSBuild='true' ContinueOnError='true'>
      <Output TaskParameter="ConsoleOutput" PropertyName="GitBranch" />
    </Exec>
    <Message Text="Current Git Branch: $(GitBranch)" Importance="high" />
	 <PropertyGroup>
      <ProType Condition="'$(GitBranch)' == 'release'">Beta</ProType>
      <ProType Condition="'$(GitBranch)' != 'release' and '$(GitBranch)' != 'master'">Alpha</ProType>
    </PropertyGroup>
    <Message Text="Setting AssemblyVersion to 1.0.$(Year).$(MonthDay)" Importance="high" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="//using System.Reflection;" Overwrite="true" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTitle(&quot;ServiceHost&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyDescription(&quot;统一登陆平台&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyConfiguration(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCompany(&quot;COM&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyProduct(&quot;ServiceHost&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCopyright(&quot;Copyright ?  COM&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyTrademark(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyCulture(&quot;&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Runtime.InteropServices.ComVisible(false)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Windows.ThemeInfo(System.Windows.ResourceDictionaryLocation.None, System.Windows.ResourceDictionaryLocation.SourceAssembly)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyVersion(&quot;01.00.00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyFileVersion(&quot;01.00.00$(Year).$(MonthDay)&quot;)]" Overwrite="false" />
    <WriteLinesToFile File="$(MSBuildThisFileDirectory)Properties\AssemblyInfo.cs" Lines="[assembly: System.Reflection.AssemblyInformationalVersion(&quot;01.00.00$(Year).$(MonthDay)$(ProType)&quot;)]" Overwrite="false" />
  </Target>
