WPF linq 和 ini文件读写

Linq ： var view = from Prepo in Olist   where Prepo.EmployeeId == pre.Id  select Prepo;
在Debug 下面生成ini 文档 mean.ini
内容：
[basetostring]
 stringUrl=xiaohui
 pass=xiaohui
 renzi=ollalal在项目中生成 OperatorFile.cs 用来读ini
引用DllImport  命名空间为using System.Runtime.InteropServices;
OperatorFile.cs
[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();
        }读取：
 string strServer = OperatorFile.GetIniFileString("basetostring", "stringUrl", "", Environment.CurrentDirectory + "\\mean.ini");
  
         string strUserID = OperatorFile.GetIniFileString("basetostring", "pass", "", Environment.CurrentDirectory + "\\mean.ini");
  
         string strPwd = OperatorFile.GetIniFileString("basetostring", "renzi", "", Environment.CurrentDirectory + "\\mean.ini");
