            config = ConfigurationManager.OpenExeConfiguration(configPath);
            ConnectionStringsSection connectionString = (ConnectionStringsSection)config.GetSection("connectionStrings");
            AppSettingsSection appSetting = (AppSettingsSection)config.GetSection("appSettings");
            connStr = connectionString.ConnectionStrings["DBConn"].ConnectionString;
            name = appSetting.Settings["LoginName"].Value;
            password = appSetting.Settings["Password"].Value;
            svr = appSetting.Settings["SvrAd"].Value;
