推荐答案

应该是这样的。

    var request = HttpWebRequest.Create("http://www.google.com") as HttpWebRequest;
    if (request != null)
    {
        var response = request.GetResponse() as HttpWebResponse;

        string contentType = "";

        if (response != null)
            contentType = response.ContentType;
    }
