C#-应用程序配置不变 [英] C# - app config doesn't change

问题描述

我想将一些设置保存在配置文件中以备将来使用. 我正在尝试使用在所有教程中看到的常规代码-

I want to save some settings on a config file for future use. I'm trying to use the regular code that I see on all the tutorials -

 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
 config.AppSettings.Settings["username"].Value = m_strUserName;

 // I also tried - 
 //config.AppSettings.Settings.Remove("username");
 //config.AppSettings.Settings.Add("username", m_strUserName);

 config.Save(ConfigurationSaveMode.Modified);
 ConfigurationManager.RefreshSection("appSettings");

现在-我可以看到在运行时-调试"文件夹中的文件"... vshost.exe.config"已更改，关闭我的应用程序后仍要更改-所有更改都将被删除. 我该怎么办?

Now - I can see that on runtime - the file "...vshost.exe.config" on "Debug" folder is changes, nut when I close my application - all the changes are deleted. What can I do?

推荐答案

要使用普通exe的配置文件进行测试，请在项目属性菜单的调试"选项卡中取消选中启用Visual Studio宿主过程"复选框.这将使Visual Studio不再使用vshost.exe文件启动，并且将使用正确的配置文件.

To test using the normal exe's config file un-check the box for "Enable the Visual Studio Hosting Process" in the "Debug" tab in the project properties menu. That will make visual studio no-longer use the vshost.exe file to launch and the correct config file will be used.
