I'm trying to convert a piece of Objective-C code into C# for use with Monotouch and I have no idea what to use to replace stringWithContentsOfUrl Should I use something like:

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://www.helephant.com");
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK &&
    response.ContentLength > 0){
    TextReader reader = new StreamReader(response.GetResponseStream());
    string text = reader.ReadToEnd();
    Console.Write(text);
}

Is that even safe to use in MonoTouch? Will it work for the iPhone?
