PipeStream.BeginWrite Method (Byte, Int32, Int32, AsyncCallback, Object)
Begins an asynchronous write operation.
Assembly: System.Core (in System.Core.dll)
[SecurityCriticalAttribute] [HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)] public override IAsyncResult BeginWrite( byte buffer, int offset, int count, AsyncCallback callback, object state )
The buffer that contains the data to write to the current stream.
The zero-based byte offset in buffer at which to begin copying bytes to the current stream.
The maximum number of bytes to write.
The method to call when the asynchronous write operation is completed.
A user-provided object that distinguishes this particular asynchronous write request from other requests.
buffer is null.
offset is less than 0.
count is less than 0.
count is greater than the number of bytes available in buffer.
The pipe is closed.
The pipe does not support write operations.
The pipe is disconnected, waiting to connect, or the handle has not been set.
The pipe is broken or another I/O error occurred.
EndWrite must be called once for every call to . This can be done either in the same code that called or in a callback that is passed to .
If the pipe is closed or an invalid argument is passed to EndWrite method., the appropriate exceptions are raised immediately. Errors that occur during an asynchronous write request occur on the thread pool thread that is performing the request. The exceptions are raised when the code calls the
