如何在C#Winforms中的app.config中保存配置

Question

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

Answer 1

在ASP.NET中:

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

在WinForms中:

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