範例

以下程式碼範例利用 FORM 物件名稱尋找物件，並以程式化方式將其資料提交給伺服器。 程式碼範例要求你的應用程式承載一個 WebBrowser 名為 webBrowser1的控制項。

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
