【C#】 C# 配置文件读取数组：读 int[], float[], string[]，bool[]；读 int, float, string,bool；，错误输出，长度判定等

主要功能

• 1.读取 int, float, string，bool（getInt, getFloat, getString,getBool）。
• 2.读取 int, float, string 数组（getIntArray, getFloatArray, getStringArray，getBoolArray）。
• 3.自动判断数组长度，错误输出等。
• 4.bool 类型大小写不敏感（true/false、TRUE/FALSE、TrUe/FaLsE 都可正确解析）。

配置文件示例

[imgPro]
//int
times = 3
//float
ratio = 0.32
//String
bar = small
//bool
bSave = true


//int数组
outImg_offsetX = -275, -354, -290, -70, -70, -290
//float数组
SFRthres_V = 0.2f, 0.2f, 0.2f, 0.2f, 0.2f, 0.2f
//String数组
Region = A1,B2,C3,D4
//bool数组
select = true,false,false,false

2 Program.cs 文件调用读取配置文件

读取以下配置文件数据

using System;

namespace FileHelper
{
    class Program
    {
        static void Main(string[] args)
        {
            Config_Helper config = new Config_Helper();
            string errorMsg;

            // **读取单个值**
            int times = config.GetIniInt("imgPro", "times", 0);
            float ratio = config.GetIniFloat("imgPro", "ratio", 0f);
            string bar = config.GetIniString("imgPro", "bar", "default");
            bool bSave = config.GetIniBool("imgPro", "bSave", false);

            // **读取数组**
            int[] outImg_offsetX = config.GetIniIntArray("imgPro", "outImg_offsetX", out errorMsg);
            float[] SFRthres_V = config.GetIniFloatArray("imgPro", "SFRthres_V", out errorMsg);
            string[] Region = config.GetIniStringArray("imgPro", "Region", out errorMsg);
            bool[] Select = config.GetIniBoolArray("imgPro", "select", out errorMsg);

            // **打印读取结果**
            Console.WriteLine("\n==== 配置参数 ====");
            Console.WriteLine($"times: {times}");
            Console.WriteLine($"ratio: {ratio}");
            Console.WriteLine($"bar: {bar}");
            Console.WriteLine($"bSave: {bSave}");

            Console.WriteLine("\noutImg_offsetX: " + string.Join(", ", outImg_offsetX));
            Console.WriteLine("SFRthres_V: " + string.Join(", ", SFRthres_V));
            Console.WriteLine("Region: " + string.Join(", ", Region));
            Console.WriteLine("select: " + string.Join(", ", Select));
