WPF C# 循环读取 INI 文件：使用 [DllImport("kernel32")] 方法

可以使用以下代码来循环读取ini文件下的内容：

using System.Runtime.InteropServices;

public class IniFile
{
    private string path;

    [DllImport('kernel32')]
    private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);

    [DllImport('kernel32')]
    private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

    public IniFile(string INIPath)
    {
        path = INIPath;
    }

    public void WriteValue(string section, string key, string value)
    {
        WritePrivateProfileString(section, key, value, this.path);
    }

    public string ReadValue(string section, string key)
    {
        StringBuilder sb = new StringBuilder(255);
        GetPrivateProfileString(section, key, '', sb, 255, this.path);
        return sb.ToString();
    }

    public List<string> ReadSection(string section)
    {
        List<string> result = new List<string>();
        StringBuilder sb = new StringBuilder(32768);
        GetPrivateProfileString(section, null, '', sb, 32768, this.path);
        string[] keys = sb.ToString().Split('\0');

        foreach (string key in keys)
        {
            if (!string.IsNullOrEmpty(key))
            {
                result.Add(key);
            }
        }

        return result;
    }

    public Dictionary<string, string> ReadSectionValues(string section)
    {
        Dictionary<string, string> result = new Dictionary<string, string>();
        List<string> keys = ReadSection(section);

        foreach (string key in keys)
        {
            result.Add(key, ReadValue(section, key));
        }

        return result;
    }
}

使用方法：

IniFile ini = new IniFile('path/to/ini/file.ini');

// 读取指定section下的所有key
List<string> keys = ini.ReadSection('写日志');

foreach (string key in keys)
{
    // 读取指定section下指定key的值
    string value = ini.ReadValue('写日志', key);
    Console.WriteLine(key + '=' + value);
}

输出结果：
