C# ClickOnce 应用程序的“添加或删除程序”图标

我已经尝试过Stack Overflow问题中的解决方案“添加或删除程序”中 ClickOnce 应用程序的自定义图标 https://stackoverflow.com/questions/10927109/icon-for-click-once-app-in-add-or-remove-programs/11096813#11096813 and 有没有办法在“添加或删除程序”中更改 ClickOnce 应用程序的图标？ https://stackoverflow.com/questions/13245056.

所以，这是我的实现。两者都可以编译，并且在代码运行时不会引发异常。我将 ClickOnce 安装文件发布到网络服务器，然后在从计算机卸载后安装它。当我进入控制面板时添加或删除程序，我仍然看到我的程序的通用图标。在其他地方我都没有遇到问题，并且我的图标显示得很好。

/*  METHOD ONE */

    if (System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed && ApplicationDeployment.CurrentDeployment.IsFirstRun)

        try
        {
            Assembly code = Assembly.GetExecutingAssembly();
            AssemblyDescriptionAttribute asdescription =
                (AssemblyDescriptionAttribute)Attribute.GetCustomAttribute(code, typeof(AssemblyDescriptionAttribute));
            string assemblyDescription = asdescription.Description;

            //The icon is included in this program
            string iconSourcePath = Path.Combine(System.Windows.Forms.Application.StartupPath, "forico4.ico");

            if (!File.Exists(iconSourcePath))
                return;

            RegistryKey myUninstallKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall");
            string[] mySubKeyNames = myUninstallKey.GetSubKeyNames();
            for (int i = 0; i < mySubKeyNames.Length; i++)
            {
                RegistryKey myKey = myUninstallKey.OpenSubKey(mySubKeyNames[i], true);
                object myValue = myKey.GetValue("DisplayName");

在查看注册表并复制其他应用程序的设置后，我终于弄清楚了。奇怪的是，您无法在 ClickOnce 部署的应用程序中引用 EXE 文件。至少我无法让它发挥作用。所以，我又转而参考.ico反而。请务必阅读评论！

using Microsoft.Win32;
//Call this method as soon as possible

        try
        {
            // Set the name of the application EXE file - make sure to include `,0` at the end.
            // Does not work for ClickOnce applications as far as I could figure out... Note, this will probably work
            // when run from Visual Studio, but not when deployed.
            //string iconSourcePath = Path.Combine(System.Windows.Forms.Application.StartupPath, "example.exe,0");
