App.config修改在退出后还原

Question

我正在修改MyApp.vhost.exe，并且正如我在文本编辑器中看到的那样修改了App.vhost.exe，但是当我停止调试应用程序时，App.config值恢复为原来的值。更改之前。我在做错什么或我想念什么？

Configuration exeConfiguration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var section = exeConfiguration.GetSection(monitorSectionElementName);

if (section != null)
{
    var monitorPathElements = (section as MonitorSection).MonitorPaths;
    monitorPathElements[monitorPath].CheckSum = checkSum;
}

exeConfiguration.Save(ConfigurationSaveMode.Full, true);
ConfigurationManager.RefreshSection(monitorSectionElementName);
