NetworkStream.DataAvailable Property

Definition

Gets a value that indicates whether data is available on the NetworkStream to be immediately read.

public:
 virtual property bool DataAvailable { bool get(); };
public virtual bool DataAvailable { get; }
member this.DataAvailable : bool
Public Overridable ReadOnly Property DataAvailable As Boolean

Property Value

true if data is available on the stream to be read; otherwise, false.

Exceptions

The underlying Socket is closed.

Use the ErrorCode property to obtain the specific error code and refer to the Windows Sockets version 2 API error code documentation for a detailed description of the error.

Remarks

Use the DataAvailable property to determine if data is queued to be immediately read. If DataAvailable is true, a call to Read returns immediately. If the remote host shuts down or closes the connection, DataAvailable may throw a SocketException.

Note

Do not use DataAvailable to determine whether the transmission has ended. Even if there's no data available to be immediately read, the underlying socket may receive more data later.
