stream不支持并发IO读取或写入操作

Question

I'm using a network stream to read data from network in an ASP.NET application and I get this error while trying to read from the stream:

stream does not support concurrent IO read or write operations

It happens sometimes. Any idea ?

Answer 1

It sounds simply as though you are trying to do two different operations on the same stream at the same time from different threads. Adding a lock ( Monitor ) or Mutex should help synchronise access to the stream.
