HttpWebRequest.Method 属性

public static void GetHead(string url)
{
var http = (HttpWebRequest)WebRequest.Create(url);
http.Method = "HEAD";//设置Method为HEAD
http.UserAgent = "Tujia-Auto-Test";
try
{
HttpWebResponse response = (HttpWebResponse)http.GetResponse();
Console.Write(Convert.ToInt32(response.StatusCode) + " " + response.StatusCode.ToString());//Statuscode 为枚举类型，200为正常，其他输出异常，需要转为int型才会输出状态码
response.Close();
}
catch (WebException ex)
{
Console.WriteLine(Convert.ToInt32(((HttpWebResponse)ex.Response).StatusCode)+"  "+((HttpWebResponse)ex.Response).StatusCode.ToString());
}
}
