winform 使用 webclient 上傳

 

 

  public void ProcessRequest(HttpContext context)        {            HttpPostedFile file = context.Request.Files[0];            file.SaveAs(context.Server.MapPath("~/uploadimages/") + file.FileName);        }

 

     string strurl = "http://localhost/Provider/HandlerUpImage.ashx";                           WebClient webclient = new WebClient();                byte[] buffer = webclient.UploadFile(strurl, "POST", @"C:\a.txt");                using (FileStream fs = new FileStream(@"C:\a.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite))                {                    fs.Write(buffer, 0, buffer.Length);                }
