        offset:int * 
        count:int -> int  
override Read : 
        buffer:byte[] * 
        offset:int * 
        count:int -> int

Parameters

buffer
Type: System.Byte[]

A Byte array that receives the bytes read from this stream.

offset
Type: System.Int32

A Int32 that contains the zero-based location in buffer at which to begin storing the data read from this stream.

count
Type: System.Int32

A Int32 that contains the maximum number of bytes to read from this stream.

Return Value

Type: System.Int32
A Int32 value that specifies the number of bytes read. When there is no more data to be read, returns 0.

ExceptionCondition
ArgumentNullException

buffer is a null reference (Nothing in Visual Basic).

ArgumentException

offset < 0.

-or-

offset > the length of buffer.

-or-

offset + count > the length of buffer.

IOException

The read operation failed. Check the inner exception, if present to determine the cause of the failure.

NotSupportedException

There is already a read operation in progress.

ObjectDisposedException

This object has been closed.

InvalidOperationException

Authentication has not occurred.

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 AuthenticateAsClient, or BeginAuthenticateAsClient, AuthenticateAsServer, BeginAuthenticateAsServer methods.

To perform this operation asynchronously, use the BeginRead method.
