trying to InvokeMember a submit button with c#

Question

1. This is the code of the website :

   function checkSubmit(e)
   {
      if(e && e.keyCode == 13)
      {
         document.frmLogin.submit();
      }
   }
   <div class="enterButton" onclick="document.frmLogin.submit()">Sign in</div>
   

2. This is what I tried in c# :

   HtmlElementCollection elc1 = webBrowser1.Document.GetElementsByTagName("div");
   foreach (HtmlElement element in elc1)
   {
       if (element.GetAttribute("InnerHtml").Equals("<DIV onclick=document.frmLogin.submit() class=enterButton>Sign in</DIV>"))
       {
           element.InvokeMember("submit()");
       }
   }
   

3. The foreach is working and the if statement is working when it gets to the InvokeMember nothing happens.

Answer 1

Try the Invoke member method without the brackets.

 element.InvokeMember("submit");

Answer 2

Sorry for the trouble I just was at the wrong element:

if (element.GetAttribute("InnerHtml").Equals("Sign in"))
{
element.InvokeMember("click");
}

now it works....
