string Path = "http://" + HttpContext.Current.Request.Url.Host + ":" + HttpContext.Current.Request.Url.Port;
string url = Path + AuditNameImagePath;//生成路径AP转换用
String fileName = url.Substring(url.LastIndexOf("/") + 1);
String refer = url.Substring(0, url.LastIndexOf("/") + 1);
System.Net.HttpWebRequest req = System.Net.HttpWebRequest.Create(url) as System.Net.HttpWebRequest;
req.AllowAutoRedirect = true;
req.Referer = refer;
req.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; zh-CN; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13";
System.Net.HttpWebResponse res = req.GetResponse() as System.Net.HttpWebResponse;
System.IO.Stream stream = res.GetResponseStream();
System.IO.MemoryStream memoryStream = new System.IO.MemoryStream();
byte[] buffer = new byte[32 * 1024];
int bytes;
while ((bytes = stream.Read(buffer, 0, buffer.Length)) > 0)
{
memoryStream.Write(buffer, 0, bytes);
}
byte[] imgBytesIn = memoryStream.GetBuffer();
res.Close();
memoryStream.Dispose();
