WPF中读写app.config操作

首先在App.config添加设置

<appSettings>
      <add key="SeatRow" value="5"/>
      <add key="SeatColumn" value="5"/>
appSettings>

写操作

Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
cfa.AppSettings.Settings["SeatColumn"].Value = "4";
cfa.Save(ConfigurationSaveMode.Modified);
//刷新
ConfigurationManager.RefreshSection("appSettings");

读操作

ConfigurationManager.AppSettings["SeatRow"]
