这个功能在windows上测试安装卸载时，有时会用到

    Shell shell = new Shell();  
    Folder folder = shell.NameSpace(Path.GetDirectoryName(appPath));  
    FolderItem app = folder.ParseName(Path.GetFileName(appPath));  
    string sVerb = isLock ? "锁定到任务栏(&K)" : "从任务栏脱离(&K)";  
       
    foreach (FolderItemVerb Fib in app.Verbs())  
    {  
        if (Fib.Name == sVerb)  
        {  
           Fib.DoIt();  
           return true;  
        }  
    }  
       
    return false;
