我需要一个元素按类型在C＃中的HTML看起来是这样的：

I need to get a element by type in C# the HTML looks like this:

<button type="submit" class="orangeBtn">Send Invitations</button>

和我希望它能够在那里我可以调用（点击），但它没有出现在C＃中工作。我现在的code是：

And I want it to be able to where I can invoke("click") it, but it isn't appearing to work in C#. My current code is:

HtmlElement m_SubmitField = m_Browser.Document.All["orangeBtn"];

if (m_SubmitField != null)
    m_SubmitField.InvokeMember("click");

是否有其他的工作方式做到这一点？

Is there an alternative working way to do this?

这是不是我的服务器，所以我不能编辑HTML或添加的jQuery。

This is NOT my server, so I can't edit the HTML or add jquery.

我在做一个自动化的应用程序发送邀请给朋友们，我想加入，但他们提出不作为上面看到一个ID或名称的按钮，所以反正是有有它调用（点击）在C＃使用不同的方法？

I'm making an automated application to send invites to friends that I want to join, but they made the button without a id or name as seen above, so is there anyway to have it invoke("click") in C# using a different method?

感谢。

推荐答案

您可以使用的getElementsByTagName 。

var elements = m_Browser.Document.GetElementsByTagName("button");
foreach (HtmlElement element in elements)
{
     // If there's more than one button, you can check the
     //element.InnerHTML to see if it's the one you want
     if (element.InnerHTML.Contains("Send Invitations"))
     {
          element.InvokeMember("click");
     }
}
