C# C/S 结构操作Ini系统文件

Winfrom 开发时,有时会将一些系统某个设置保存到Ini 类型的文件中.下面提供操作Ini 文件的代码：

 public static class IniFiles
    {
        [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 FilePath;

        /// <summary>
        /// 写入Ini文件
        /// </summary>
        /// <param name="section">项目名称(如 [TypeName] )</param>
        /// <param name="key">键</param>
        /// <param name="value">值</param>
        public static void IniWriteValue(string section, string key, string value)
        {
            WritePrivateProfileString(section, key, value, FilePath);
        }

        /// <summary>
        /// 读出Ini文件
        /// </summary>
        /// <param name="section">项目名称(如 [TypeName] )</param>
        /// <param name="key">键</param>
        public static string IniReadValue(string section, string key)
        {
            StringBuilder temp = new StringBuilder(500);
            int i = GetPrivateProfileString(section, key, "", temp, 500, FilePath);
            return temp.ToString();
        }

        /// <summary>
        /// 验证文件是否存在
        /// </summary>
        /// <returns>布尔值</returns>
        public static bool ExistIniFile()
        {
            return File.Exists(FilePath);
        }
    }
