如何以编程方式检索ClickOnce更新程序？

Question

我有一个ClickOnce应用程序，我希望每次启动计算机时都会根据用户的选择运行。为此，我将我的应用程序的可执行文件添加到注册表。但是，这直接启动应用程序，滑动ClickOnce搜索更新。 所以我需要ClickOnce应用程序的路径在注册表中正确设置。

执行.appref-ms文件，即启动菜单快捷方式（在安装ClickOnce时创建）执行。这就是我们在VB.Net中所做的：

Dim FilePath As String = Environment.GetFolderPath(Environment.SpecialFolder.StartMenu) + "\Programs\[your publisher name]\[your app name]" 
Static p As Process 

Dim files As String() 

Try 
    files = Directory.GetFiles(FilePath, "[your shortcut name]*.appref-ms") 
Catch ex As Exception 
    '' an exception is thrown if no matching file exists 
    '' you can open your ClickOnce URL in a webbrowser control here 
    Return 
End Try 

If files.Length = 1 Then 
    Dim psi As ProcessStartInfo = New ProcessStartInfo(files(0)) 
    psi.Arguments = "" 
    psi.WorkingDirectory = FilePath 
    psi.UseShellExecute = True 
    psi.CreateNoWindow = False 
    psi.WindowStyle = ProcessWindowStyle.Normal 
    psi.RedirectStandardOutput = False 
    psi.RedirectStandardError = False 

    Try 
     p = Process.Start(psi) 
     p.WaitForExit(50) 
     p.Close() 
    Catch ex As Exception 
     ' handle error 
    End Try 
Else 
    ' more than one would be an anomaly 
    If files.Length > 1 Then 
     Dim f As String 
     For Each f In files 
      File.Delete(f) 
     Next 
    End If 

    '' you can open your ClickOnce URL in a webbrowser control here 
End If
