c#winfrom读写ini文件（[set] User_ID=123 PassWord=MTIz [dev_qty] 点胶机=44 激光分板机=17 镭雕机=3）

你可以使用 `System.IO` 命名空间中的 `StreamReader` 和 `StreamWriter` 类来读写 INI 文件。下面是一个示例代码：

using System;
using System.Collections.Generic;
using System.IO;

public class IniFile
{
    private readonly string filePath;
    private Dictionary<string, Dictionary<string, string>> sections;

    public IniFile(string filePath)
    {
        this.filePath = filePath;
        sections = new Dictionary<string, Dictionary<string, string>>();
        ParseIniFile();
    }

    private void ParseIniFile()
    {
        string currentSection = null;
        Dictionary<string, string> currentProperties = null;

        foreach (string line in File.ReadLines(filePath))
        {
            if (line.StartsWith("[") && line.EndsWith("]"))
            {
                currentSection = line.Substring(1, line.Length - 2);
                currentProperties = new Dictionary<string, string>();
                sections[currentSection] = currentProperties;
            }
            else if (!string.IsNullOrWhiteSpace(line))
            {
                string[] parts = line.Split('=');
                if (parts.Length == 2)
                {
                    string key = parts[0].Trim();
                    string value = parts[1].Trim();
                    currentProperties[key] = value;
                }
            }
        }
    }

    public string GetValue(string section, string key)
    {
        if (sections.TryGetValue(section, out var properties))
        {
            if (properties.TryGetValue(key, out var value))
            {
                return value;
            }
        }
        return null;
    }

    public void SetValue(string section, string key, string value)
    {
        if (!sections.ContainsKey(section))
        {
            sections[section] = new Dictionary<string, string>();
        }
        sections[section][key] = value;
    }

    public void Save()
    {
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            foreach (var section in sections)
            {
                writer.WriteLine($"[{section.Key}]");
                foreach (var property in section.Value)
                {
                    writer.WriteLine($"{property.Key}={property.Value}");
                }
            }
        }
    }
}

public class Program
{
    public static void Main()
    {
        IniFile ini = new IniFile("path/to/your/file.ini");

        // 读取值
        string userID = ini.GetValue("set", "User_ID");
        string password = ini.GetValue("set", "PassWord");
        int glueMachineQty = int.Parse(ini.GetValue("dev_qty", "点胶机"));

        Console.WriteLine($"User ID: {userID}");
        Console.WriteLine($"Password: {password}");
        Console.WriteLine($"Glue Machine Qty: {glueMachineQty}");

        // 设置新值
        ini.SetValue("set", "User_ID", "456");
        ini.SetValue("set", "PassWord", "NDU2");
        ini.SetValue("dev_qty", "点胶机", "55");

        // 保存更改
        ini.Save();
    }
}

将上述代码中的 `path/to/your/file.ini` 替换为你的 INI 文件的路径。这个示例代码可以读取 INI 文件中的值，并且可以设置新的值并保存更改。
