Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click 

     WebBrowser1.Document.GetElementById("xn_logout").InvokeMember("click") 
    End Sub 

私はここで間違っているのですか？私が得たものである私の研究によると

Answer 1

'WebBrowser1.Document.GetElementById("xn_username").InvokeMember("click") 

    Dim HtmlElementcoll As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a") 
    For Each elem As HtmlElement In HtmlElementcoll 
     ' Check the attributtes you want 
     If elem.GetAttribute("dojotype") = "PostLink" Then 
      'Check even the text if you want 
      ' If elem.InnerText = "Sign In" Then 
      'Invoke your event 
      elem.InvokeMember("click") 
      'End If 
     End If 
    Next 
End Sub
