C#ClickOnce应用程序的"添加或删除程序"图标

Question

我在"添加或删除程序"中尝试了Stack Overflow问题解决方案ClickOnce应用程序的自定义图标,是否有办法在"添加或删除程序" 中更改ClickOnce应用程序的图标？.

所以,这是我的实现.它们都编译,并且在运行代码时不会抛出任何异常.我将ClickOnce安装文件发布到Web服务器,然后在从计算机卸载后安装它.当我转到控制面板添加或删除程序时,我仍然看到我的程序的通用图标.在其他任何地方我都没有问题,我的图标显示得很好.

在查看注册表并复制其他应用程序的设置之后，我终于找到了答案。奇怪的是，您无法在ClickOnce部署的应用程序中引用EXE文件。至少我无法使它正常工作。因此，我.ico转而引用了。请务必阅读评论！

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

private static void SetAddRemoveProgramsIcon()
{
    //Only execute on a first run after first install or after update
    if (ApplicationDeployment.CurrentDeployment.IsFirstRun)
    {
        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");
            // Reverted to using this instead (note this will probably not work when run from Visual Studio, but will work on deploy.
            string iconSourcePath = Path.Combine(System.Windows.Forms.Application.StartupPath, "example.ico");
            if (!File.Exists(iconSourcePath))
            {
                MessageBox.Show("We could not find the application icon. Please notify your software vendor of this error.");
                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");
                Console.WriteLine(myValue.ToString());
                // Set this to the display name of the application. If you are not sure, browse to the registry directory and check.
                if (myValue != null && myValue.ToString() == "Example Application")
                {
                    myKey.SetValue("DisplayIcon", iconSourcePath);
                    break;
                }
            }
        }
        catch(Exception mye)
        {
            MessageBox.Show("We could not properly setup the application icons. Please notify your software vendor of this error.\r\n" + mye.ToString());
        }
    }
