vb.net - 请帮助：单击 VB.NET (WEBBrowser) 中的提交按钮

Question

我正在开发一个 vb.net 应用程序。我有一个网络浏览器，我需要在网络表单上填写一些信息并单击提交按钮。一切正常，除了提交，什么都没有发生！！！请帮忙 ！

html页面：

 <p>
        <input id="submit" name="submit" type="submit" value="Publicar" />

 </p>

我的代码：

  Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
    If PAgina = 0 Then
        Dim document As HtmlDocument = WebBrowser1.Document
        Dim inputValue As HtmlElement = document.GetElementById("title")
        inputValue.SetAttribute("value", "sdf  fdd  fh fgh fgh fg hfg hf ghfgh fg fg f hf fgh ")

        inputValue = document.GetElementById("zone")
        inputValue.SetAttribute("value", "Logroño")

        inputValue = document.GetElementById("editor")
        inputValue.SetAttribute("value", "Logroño s dfs dfs fsdfsd fsddfg dfg df gdf gdf gd df sd sd fsd fsdfsdfsdsdfsdf sdsdf")


        inputValue = document.GetElementById("email")
        inputValue.SetAttribute("value", "dfgdgrankkk@gmail.com")


        WebBrowser1.AllowNavigation = True

        **Dim submitButton As HtmlElement = document.GetElementById("submit")
        submitButton.InvokeMember("submit")
        ' WebBrowser1.Document.Forms("post").InvokeMember("submit")**
        PAgina = 1
    End If

结束子

尝试

.InvokeMember("click")  ; // instead of "submit" ?

或尝试在提交前添加几秒钟的延迟。
