示例

下面的代码示例使用其名称查找对象 FORM ，并通过编程方式将其数据提交到服务器。 The code example requires that your application hosts a WebBrowser control named webBrowser1.

private void SubmitForm(String formName)
{
    HtmlElementCollection elems = null;
    HtmlElement elem = null;

    if (webBrowser1.Document != null)
    {
        HtmlDocument doc = webBrowser1.Document;
        elems = doc.All.GetElementsByName(formName);
        if (elems != null && elems.Count > 0)
        {
            elem = elems[0];
            if (elem.TagName.Equals("FORM"))
            {
                elem.InvokeMember("Submit");
            }
        }
    }
}

Private Sub SubmitForm(ByVal FormName As String)
    Dim Elems As HtmlElementCollection
    Dim Elem As HtmlElement

    If (WebBrowser1.Document IsNot Nothing) Then
        With WebBrowser1.Document
            Elems = .All.GetElementsByName(FormName)
            If (Not Elems Is Nothing And Elems.Count > 0) Then
                Elem = Elems(0)
                If (Elem.TagName.Equals("FORM")) Then
                    Elem.InvokeMember("Submit")
                End If
            End If
        End With
    End If
End Sub

注解

Id虽然属性必须是唯一HtmlElement的，但多个元素可以使用同一Name属性。
