Why can't I read Http Request Input stream twice?

Question

I was putting in some debugging code to test some things, and then the debug code didn\'t behave as expected. The example below is a simplified code to demonstrate my questi

Answer 1

StreamReader calls Dispose on given stream when disposed. To leave the stream open use the appropriate constructor for the StreamReader. Or better yet, just copy it to a buffer. From MSDN:

When reading from a Stream, it is more efficient to use a buffer that is the same size as the internal buffer of the stream.

See this question for example.

Answer 2

HttpContext.Current.Request.InputStream.Position=0;

Once you read the position goes to last value, from there its trying to read second time. So before you read, set the position to zero.

Hope it helps.
