C# WebBrowser how to click a button

I try to make a program and I need to click a button using my program webBrowser1.Document.GetElementById("submit").InvokeMember("click");

This doesn't work because this button has no id.
Here is the code of the button:

<a class="buttonMtel" tabindex="6" onclick="document.forms['SMSForm'].submit()">
    <span>Изпрати</span>
</a>
<span>Изпрати</span>.

Please help. Thank you.

Assuming that your button is the only anchor with class="buttonMtel", you could use the GetElementByTagName method and then locate the desired element:

var anchors = webBrowser1.Document.GetElementByTagName("a");
foreach (HtmlElement anchor in anchors)
{
    if (anchor.GetAttribute("class") == "buttonMtel") 
    {
        // we have found the button => click on it
        anchor.InvokeMember("click");
        break;
    }
}

or if you prefer LINQ:

var anchor = webBrowser1
    .Document
    .GetElementByTagName("a")
    .Cast<HtmlElement>()
    .FirstOrDefault(anchor => anchor.GetAttribute("class") == "buttonMtel");
if (anchor != null)
{
    anchor.InvokeMember("click");
}

If on the other hand you have multiple anchors with class="buttonMtel" in your DOM you will need a different approach. Depending on the actual structure of your DOM you might need to first locate some parent element and then reach up to the desired button.
