webservice

Hello friends,
I am new to webservices, i am calling my local webservice by http-post method like this:

byte[] data = System.Text.Encoding.ASCII.GetBytes("a=" + TextBox1.Text+"&b="+TextBox2.Text);
System.Net.WebRequest request = System.Net.HttpWebRequest.Create("http://localhost:5083/myservicecodeproject1/WebServicetakinganewcsfile.asmx/add");
request.Method = "POST";
request.ContentLength = data.Length;
request.ContentType = "application/x-www-form-urlencoded";

System.IO.Stream str = request.GetRequestStream();
str.Write(data, 0, data.Length);
str.Flush();       

Now i am using the response to get my result

System.Net.WebResponse response = request.GetResponse();
System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream());
string result=reader..ReadToEnd();

now this result string gets :

<?xml version="1.0" encoding="utf-8"?>
<int xmlns="http://tempuri.org/">
2
</int>

Now here is my question HOW to get this int "2" result into a integer type variable...

Thanks a lot in advance
