问题描述

我使用ASP.Net MVC 4和WebImage帮手。我需要通过FTP上传我的WebImage对象。我只是不知道如何让WebImage参数发送给我的RequestStream.Write

下面是一些代码...

  WebImage照片= WebImage.GetImageFromRequest（）; 
字符串文件名= System.IO.Path.GetFileName（photo.FileName）; 
 
的FtpWebRequest请求=（的FtpWebRequest）WebRequest.Create（FTPaddress +/图片/+文件名）; 
 request.Method = WebRequestMethods.Ftp.UploadFile; 
 request.Credentials =新的NetworkCredential（****，*****）; 
 request.UsePassive = TRUE; 
 
 request.ContentLength = ???????; 
 
字节[]缓冲= ????????; //这不是photo.GetBytes; 
 
流requestStream = request.GetRequestStream（）; 
 requestStream.Write（缓冲液，0，request.ContentLength）; 
 requestStream.Close（）; 
 
 FtpWebResponse响应=（FtpWebResponse）request.GetResponse（）; 
 
 response.Close（）;

和我将能够在事后利用photo.Save（）以FTP路径？

解决方案

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

这是你如何做到这一点，我傻。

I am using ASP.Net MVC 4 and WebImage helpers. I need to upload my WebImage object via FTP. I just don't know how to get the WebImage parameters to send to my RequestStream.Write

Here is some code...

        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();

And will I be able to use the photo.Save() to the FTP path afterwards?

解决方案

byte [] fileContents = photo.GetBytes();
request.ContentLength = fileContents.Length;

Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();

That's how you do it, silly me.
