c#读取ini配置文件、将配置数据保存至ini文件

测试代码

static void Main()
{
    string value = readini("group1", "key1", "default_value1", ".\\set.ini");
    writeini("group2", "key2", value, ".\\set.ini");
}

读取ini配置数据、将数据存储至ini文件

using System.Runtime.InteropServices;

[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 static string readini(string group, string key, string default_value, string filepath)
{
    StringBuilder temp = new StringBuilder();
    GetPrivateProfileString(group, key, default_value, temp, 255, filepath);
    return temp.ToString();
}
