A int value that specifies the number of bytes read. When there is no more data to be read, returns 0.
The method reads a maximum of count bytes from the stream and stores them in buffer beginning at offset. You cannot perform multiple simultaneous read operations.
You cannot call this method until you have successfully authenticated. To authenticate call one of the erload:System.Net.Security.SslStream.AuthenticateAsClient, or erload:System.Net.Security.SslStream.BeginAuthenticateAsClient, erload:System.Net.Security.SslStream.AuthenticateAsServer, erload:System.Net.Security.SslStream.BeginAuthenticateAsServer methods.
To perform this operation asynchronously, use the SslStream.BeginRead(Byte[], int, int, AsyncCallback, object) method.
