读取Ini文件字段

A.INI文件内容:

[DataBase]
Server=127.0.0.1
User=sa
Password=123

-------------------------------

定义共用方法

 public class OperatorFile
    {
        [DllImport("kernel32")] //引入“shell32.dll”API文件
        public static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal,
                                                         int size, string filePath);

        /// <summary>
        ///   从INI文件中读取指定节点的内容
        /// </summary>
        /// <param name="section"> INI节点 </param>
        /// <param name="key"> 节点下的项 </param>
        /// <param name="def"> 没有找到内容时返回的默认值 </param>
        /// <param name="filePath"> 要读取的INI文件 </param>
        /// <returns> 读取的节点内容 </returns>
        public static string GetIniFileString(string section, string key, string def, string filePath)
        {
            StringBuilder temp = new StringBuilder(1024);
            GetPrivateProfileString(section, key, def, temp, 1024, filePath);
            return temp.ToString();
        }
    }

调用:

 string strServer = OperatorFile.GetIniFileString("DataBase", "Server", "",
                                                             Application.StartupPath + "\\A.ini");
            //获取登录用户
            string strUserID = OperatorFile.GetIniFileString("DataBase", "User", "",
                                                             Application.StartupPath + "\\Aini");
            //获取登录密码
            string strPwd = OperatorFile.GetIniFileString("DataBase", "Password", "",
                                                          Application.StartupPath + "\\A.ini");
