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);

        }

    }
