如何在c＃winforms中的app.config文件上动态更新应用程序设置键值对

Question

如何在c＃winforms中的app.config文件上动态更新应用程序设置键值。 键，值列在下面

<appSettings>
    <add key="logPath" value="C:\EventLogs" />
    <add key="isScreenCaptureMode" value="false" />
    <add key="isStartOnSysStartUp" value="false" />
</appSettings>

Answer 1

Configuration configuration = ConfigurationManager.
OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);
configuration.AppSettings.Settings["logPath"].Value = DateTime.Now.ToString("yyyy-MM-dd");
configuration.Save();
ConfigurationManager.RefreshSection("appSettings");

Answer 2

我相信这就是你要找的东西：

using System.Configuration;

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
                config.AppSettings.Settings["isScreenCaptureMode"].Value = "true";
                config.Save(ConfigurationSaveMode.Modified);
                ConfigurationManager.RefreshSection("appSettings");
