c#之将 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。我只是不知道如何获取 WebImage 参数以发送到我的 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？

请您参考如下方法:

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

这就是你的做法，愚蠢的我。
