浅谈C#创建可扩展应用程序(二)

 本想把系统逻辑图贴出来,贴个图可真难,最终还是没贴出来 :(
我就先贴出来一些代码了,在后面讲解逻辑与思路

下面这个是我们程序的配置文件中的内容:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
    <section name="EnumerSetting"
        type="System.Configuration.SingleTagSectionHandler" />
    </configSections>
    
    <appSettings>
        <!-- config the file type 
    
        config rule:
            AssemblyName[TypeName]
            
        example:
            <add key=".mytype" value = "MyAssembly[MyType]"/>
        -->
        
        <!-- csharp code enumer -->
        <add key=".cs" value="CSharpEnumer[Enumer2006.CSharp.CSharpEnmer]"/>
        
        <!-- c/c++ -->
        <add key=".h" value="CSharpEnumer[Enumer2006.CSharp.CSharpEnmer]"/>
        <add key=".cpp" value="CSharpEnumer[Enumer2006.CSharp.CSharpEnmer]"/>
        <add key=".c" value="CSharpEnumer[Enumer2006.CSharp.CSharpEnmer]"/>
        <!-- javascript -->
        
        <!-- java -->
        
        <!-- asp/asp.net -->
        
        <!-- html/xml -->
        
        <!-- delphi -->
    </appSettings>
    
    
    <EnumerSetting>    
        
    </EnumerSetting>
</configuration>

下面是主程序代码:

using System;
using System.Windows.Forms;
using System.Threading;

namespace Enumer2006
...{
    /**//// <summary>
    /// EnmerStart

        static void Main() 
        ...{
            // ThreadException
            Application.ThreadException += new
                ThreadExceptionEventHandler(Application_ThreadException);

            // UnhandledException
            Thread.GetDomain().UnhandledException += new
                UnhandledExceptionEventHandler(Application_UnhandledException);

            //ApplicationをRun            
            Application.Run(new Form1());
        
            return;
        }

        //************************************************************************
        /**//// <summary>

        //************************************************************************
        public static void ShowErrorMessage(Exception ex)
        ...{
            MessageBox.Show(null, ex.Message + " " + ex.StackTrace, "error",
                MessageBoxButtons.OK, MessageBoxIcon.Error);
            Application.Exit();
            // append by linzc
        }
        
        ...#region 
        //************************************************************************

        //************************************************************************
        public static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
        ...{
            ShowErrorMessage(e.Exception);
        }

        //************************************************************************
        /**//// <summary>

        public static void Application_UnhandledException(object sender, UnhandledExceptionEventArgs e)

            Exception ex = e.ExceptionObject as Exception;
            if (ex != null)
            ...{
                ShowErrorMessage(ex);
            }
        }
        #endregion
