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

问题描述

我想在配置文件中保存一些设置以备将来使用.我正在尝试使用我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 - 我可以在运行时看到 - 调试"文件夹上的文件...vshost.exe.config"发生了变化，当我关闭我的应用程序时很糟糕 - 所有的变化都被删除了.我能做什么?

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，请取消选中项目属性菜单中调试"选项卡中的启用 Visual Studio 托管进程"框.这将使 Visual Studio 不再使用 vshost.exe 文件来启动并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.
