VB Script to C# conversion

Hello all,

I have below code in VB Script. We are moving it out to C#, how can I achieve this in C#

xmlhttp.open "POST", URL, false  
			xmlhttp.setRequestHeader "Content-Type", "text/xml;charset=UTF-8"   
			xmlhttp.setRequestHeader "SOAPAction", "urn:retrieveCoverDecision"
			xmlhttp.send XMlMessage
If xmlhttp.Status = 12002 Then 
				'Time Out
XMLResponse = xmlhttp.responseText
Set xmlhttp = nothing

Thanks & Regards,
