我正在编写适用于WCF服务的上传控件,当我尝试上传超过1MB的文件时,我发现此错误:
{System.IO.IOException: Unable to write data to the transport connection:
An established connection was aborted by the software in your host machine.
---> System.Net.Sockets.SocketException: An established connection was aborted by the
software in your host machine
at System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
--- End of inner exception stack trace ---
at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
at System.Net.PooledStream.Write(Byte[] buffer, Int32 offset, Int32 size)
at System.Net.ConnectStream.InternalWrite(Boolean async, Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)
at System.Net.ConnectStream.Write(Byte[] buffer, Int32 offset, Int32 size)}
我不知道这是否与json max length参数有关。 我知道在web应用程序中我可以将它添加到web.config文件
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="50000000"/>
</webServices>
</scripting>
但我是WCF的新手并且不知道如何处理它......

你可能会超时。首先,在绑定中打开keepalive。其次,检查请求上的时间戳并回复。如果发送方和接收方之间存在防火墙,请确保由于空闲超时而未关闭连接。
