In ASP.NET:
在ASP.NET 中：
Configuration config = WebConfigurationManager.OpenWebConfiguration(null);
AppSettingsSection app = config.AppSettings;
app.Settings.Add("x", "this is X");
config.Save(ConfigurationSaveMode.Modified);
In WinForms:
在WinForms 中：
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:
我知道您特别要求 WinForms 解决方案，但这可能对其他人有所帮助。对于 .NET 4.0 控制台应用程序，这些都不适合我。所以我使用了以下方法并且它起作用了：
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");
}
