完整代码如下

using System;

using System.Text;

namespace myinihelp
{
    public class INIhelp
    {
        [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);

        //ini文件名称
        private static string inifilename = "Config.ini";
        //获取ini文件路径
        private static string inifilepath = Directory.GetCurrentDirectory() + "\\" + inifilename;

        /// </summary>
        /// <param name="key"></param>
        /// <returns></returns>
        public static string GetValue(string key)
        {
            StringBuilder s = new StringBuilder(1024);
            GetPrivateProfileString("CONFIG", key, "", s, 1024, inifilepath);
            return s.ToString();
        }

        /// <summary>

        {
            try
            {
                WritePrivateProfileString("CONFIG", key, value, inifilepath);
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

        {
            try
            {
                if (System.IO.File.Exists(inifilepath))
                {
                    System.IO.File.Delete(inifilepath);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
    }
}

核心代码：

[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);
