远程服务器返回错误:(550)... [英] The remote server returned an error: (550) ...

问题描述

我正在FTP上载和在ASP.NET中下载.当我尝试在上传后立即下载文件时，它会引发以下错误:

I am doing FTP upload and download in ASP.NET. When I try to download the file immediately after uploading, it is throwing the following error:

"The remote server returned an error: (550) File unavailable (e.g., file not found, no access)."

如果我等了一会儿然后尝试下载它，它工作正常.有人可以提出一种摆脱这种情况的方法吗?

PS:上载完成后，我正在将文件显示在网格中以下载它们，因此假设文件已完成.

If I wait for a minute and then try to download it, it''s working fine. Can somebody suggest a way to get out of this.

P.S.: As soon as uploading finishes, I am showing the files in a grid to download them, hence assuming that the file upload is complete.

推荐答案

我''ve之前碰到过这个问题，似乎(就我而言)它涉及服务器或客户端某处的缓存.客户端已完成数据的发送，但服务器尚未完成数据的接收和保存.

我通过在发送数据后在客户端添加延迟来解决了该问题.我不喜欢这种解决方案，但找不到其他解决方案.

I''ve run into that problem before and it appears that (in my case) it involved a cache either on the server or client somewhere. The client had finished sending the data, but the server had not finished receiving and saving it yet.

I solved it by adding a delay on the client side after sending the data. I didn''t like that solution, but I couldn''t find any other way to easily work around it.
