app.config 不保存值
我的 App.Config 类似于：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="foo" value=""/>
</appSettings>
</configuration>
我尝试使用以下方法保存 foo 值：
private void SaveValue(string value) {
var config =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings.Add("foo", value);
config.Save(ConfigurationSaveMode.Modified);
}
但这不会改变它的值。我也不例外。 如何解决这个问题？提前致谢！

I try to save the foo value using the following method:
private void SaveValue(string value) {
var config =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings.Add("foo", value);
config.Save(ConfigurationSaveMode.Modified);
}
but this not change the value of it. and I don't get a exception.

当您使用 Visual Studio 进行调试时，可能会修改
.vshost.exe.config .exe.config .exe.config 您的代码还将向配置文件添加一个额外的节点。使用类似下面的代码来更新设置：
When you are debugging with Visual Studio probably the
<yourexe>.vshost.exe.configis modified instead of the<yourexe>.exe.config. When you build the application in Release mode only the<yourexe>.exe.configexists and will be updated.Your code will also add an extra node to the configuration file. Use something like the code below to update the setting:
App.config 被复制到构建时的输出文件夹，名为
.exe.config 查看输出文件夹，您可能会发现配置文件包含您的更改。
App.config is copied to the output folder on build, named
<yourexe>.exe.config. This is the actual configuration file that is loaded and saved on runtime.Have a look in your output folder, there you will likely find that the configuration file contains your changes.
尝试先删除旧值，然后再次添加
Try by first deleting the old value and then add it again
