如何在C＃Winforms中的app.config中保存配置

Can someone give me an example of how to save a key/value in app.config using C# and WinForms?

有人能举例说明如何使用C#和WinForms在app.config中保存键/值吗?

In ASP.NET:

Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection app = config.AppSettings;
app.Settings.Add("x", "this is X");
config.Save(ConfigurationSaveMode.Modified);

In WinForms:

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
AppSettingsSection app = config.AppSettings;
app.Settings.Add("x", "this is X");
config.Save(ConfigurationSaveMode.Modified);

I know you specifically asked for WinForms solution, but this might help some others. For a .NET 4.0 console application, none of these worked for me. So I used the following and it worked:

我知道你特意要求WinForms解决方案,但这可能会帮助其他人。对于.NET 4.0控制台应用程序,这些都不适用于我。所以我使用了以下内容并且它有效:

private static void UpdateSetting(string key, string value)
{
    Configuration configuration = ConfigurationManager.
        OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);
    configuration.AppSettings.Settings[key].Value = value;
    configuration.Save();

    ConfigurationManager.RefreshSection("appSettings");
}
