I've just got an error report from a client using a program I wrote, and I've been googling the nuts off of this error and can't find anything useful. The error is:
System.Net.WebException: Error getting response stream (ReadDone2): ReceiveFailure ---> System.Exception: at System.Net.WebConnection.HandleError(WebExceptionStatus st, System.Exception e, System.String where)

The application is the launcher program for a game, it pulls down a manifest of files and patches any which are non-existent or outdated. All the files it downloads with a WebClient object, it looks like the error is being thrown by WebClient::DownloadFileAsync, but I can't find any documentation as to why this could be happening.
Any help would be much appreciated, the quicker I can fix this monday morning the better!

在sysadmin使用服务器配置播放了一点之后,这个问题似乎消失了,但是我不确定到底是怎么做的。
Does the client uses a proxy?
If yes, are you attaching the proxy to the WebClient
object?
Your error simply mentions that the file could not be found, DownloadFileAsync
needs a file stream, and if that's not there, you get an error...
Any thoughts in implementing a log system that can be activate through a parameter that would POST the log file into your FTP for example?
You could make use of several open source projects out there, like ExceptionReporter .
