Remarks

The PipeStream class provides the base class for named and anonymous pipes operations in the .NET Framework. Use the NamedPipeServerStream and NamedPipeClientStream classes for named pipe operations. Use the AnonymousPipeServerStream and AnonymousPipeClientStream classes for anonymous pipe operations.

For more information about pipes, see Pipes. For an example of anonymous pipes, see How to: Use Anonymous Pipes for Local Interprocess Communication. For an example of named pipes, see How to: Use Named Pipes for Network Interprocess Communication.

Constructors

PipeStream(PipeDirection, Int32)	Initializes a new instance of the PipeStream class using the specified PipeDirection value and buffer size.
PipeStream(PipeDirection, PipeTransmissionMode, Int32)	Initializes a new instance of the PipeStream class using the specified PipeDirection, PipeTransmissionMode, and buffer size.

Properties

InBufferSize	Gets the size, in bytes, of the inbound buffer for a pipe.
IsAsync	Gets a value indicating whether a PipeStream object was opened asynchronously or synchronously.
IsConnected	Gets or sets a value indicating whether a PipeStream object is connected.
IsHandleExposed	Gets a value indicating whether a handle to a PipeStream object is exposed.
IsMessageComplete	Gets a value indicating whether there is more data in the message returned from the most recent read operation.

Position	Gets or sets the current position of the current stream.
ReadMode	Gets or sets the reading mode for a PipeStream object.
