Send FileStream through Socket on C#

Question

i was looking for a way to send file through Socket on C# but i was not lucky to find sample code or ... as you know in Socket we should send an array of byte and array length is MaxInt and a file is larger than MaxInt. is there a way to send a FileStream through windows Socket on C# ?

Read some bytes, send some bytes, and you'll do fine.

Read the file in chunks (for example 64KB at once). Send each chuck individually. That allows you to stream arbitrarily large files.

Starting with .NET 4.0 you can use Stream.CopyTo(Stream) to make this a one-liner.

Or if on .Net 4.0 could probably just use the FileStream.CopyTo(Stream) overload and let the framework handle the chunking.

...you can't copy stream to stream until you construct a NetworkStream around the socket: msdn.microsoft.com/en-us/library/cd8fz0y3.aspx
