将WebImage上传到FTP

我正在使用ASP.Net MVC 4和WebImage助手。 我需要通过FTP上传我的WebImage对象。 我只是不知道如何将WebImage参数发送到我的RequestStream.Write

这是一些代码……

WebImage photo = WebImage.GetImageFromRequest(); string fileName = System.IO.Path.GetFileName(photo.FileName); FtpWebRequest request = (FtpWebRequest)WebRequest.Create(FTPaddress +"/images/" + fileName); request.Method = WebRequestMethods.Ftp.UploadFile; request.Credentials = new NetworkCredential("****", "*****"); request.UsePassive = true; request.ContentLength = ???????; byte[] buffer = ????????; //It's not photo.GetBytes; Stream requestStream = request.GetRequestStream(); requestStream.Write(buffer, 0, request.ContentLength); requestStream.Close(); FtpWebResponse response = (FtpWebResponse)request.GetResponse(); response.Close(); 

然后我可以使用photo.Save（）到FTP路径吗？

Answer 1

 byte [] fileContents = photo.GetBytes(); request.ContentLength = fileContents.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); requestStream.Close(); 

这就是你做的，傻我。
