Follwowing是我收到的例外：

An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full 

如何解决这个问题？如何增加缓冲区大小上传一个较大的文件到最大1 GB？请帮我解决这个问题？

Answer 1

在你使用的配置文件"basicHttpBinding_IVideoUpload"绑定transferMode="Buffered"（customBinding存在，但未使用）。您应该使用transferMode="Streamed"或"StreamedResponse"并将maxReceivedMessageSize增加到所需的大小。代码示例请参阅http://msdn.microsoft.com/en-us/library/ms789010.aspx。
