Download E-books TCP/IP Sockets in C#: Practical Guide for Programmers (The Practical Guides) PDF

By Michael J. Donahoo, Kenneth L. Calvert

"TCP/IP sockets in C# is a superb publication for an individual drawn to writing community functions utilizing Microsoft .Net frameworks. it's a particular mixture of good written concise textual content and wealthy rigorously chosen set of operating examples. For the newbie of community programming, it is a strong beginning e-book; nevertheless pros benefit from very good convenient pattern code snippets and fabric on themes like message parsing and asynchronous programming."
Adarsh Khare, SDT, .Net Frameworks workforce, Microsoft Corporation

The acclaim for the C# language and the .NET framework is ever emerging because of its ease of use, the huge category libraries to be had within the .NET Framework, and the ubiquity of the Microsoft home windows working method, to call a number of benefits. TCP/IP Sockets in C# specializes in the Sockets API, the de facto normal for writing community purposes in any programming language. beginning with uncomplicated buyer and server courses that use TCP/IP (the net protocol suite), scholars and practitioners speedy examine the fundamentals and flow directly to firsthand adventure with complex issues together with non-blocking sockets, multiplexing, threads, asynchronous programming, and multicasting. Key community programming recommendations akin to framing, functionality and deadlocks are illustrated via hands-on examples. utilizing a close but transparent, concise strategy, this ebook comprises a number of code examples and centred discussions to supply an effective realizing of programming TCP/IP sockets in C#.

Features

After a decision to Shutdown(SocketShutdown. Receive), the socket can not obtain enter. Any undelivered facts is silently discarded, and any try to learn from the socket will generate a SocketException. After Shutdown(SocketShutdown. ship) is named on a Socket, not more information can be despatched at the socket. makes an attempt to write down to the circulation additionally throw a SocketException. Any information written earlier than the decision to Shutdown(SocketShutdown. ship) will be learn through the distant socket. After this, a learn at the enter move of the distant socket will go back zero. An program calling Shutdown(SocketShutdown. ship) can proceed to learn from the socket and, equally, info will be written after calling Shutdown(SocketShutdown. Receive). within the Transcode protocol (see determine four. 3), the buyer writes the Unicode bytes, last the output move utilizing Shutdown(SocketShutdown. ship) whilst finished sending, and reads the UTF-8 byte circulation from the server. The server again and again reads the Unicode info and writes the UTF-8 info until eventually the buyer plays a shutdown, inflicting the server learn to come back zero, indicating an end-of-stream. The server then closes the relationship and exits. After the buyer calls Shutdown(SocketShutdown. Send), it must learn any ultimate UTF-8 bytes from the server. Our patron, TranscodeClient. cs, implements the customer part of the Transcode protocol. The Unicode bytes are learn from the file specified at the command line, and the UTF-8 bytes are written to a brand new file. If the Unicode filename is “data,” the UTF-8 file identify is “data. ut8. ” notice that this implementation works for small files, yet that there's a flaw that factors impasse for big files.

As we pointed out previous, a few complicated performance is out there purely within the Socket type and never the better point socket periods like TcpClient. The Shutdown() approach to the Socket classification is an instance of a characteristic that isn't at once available within the TcpClient type. besides the fact that, the TcpClient classification does provide us entry to its underlying Socket example via its secure Socket estate. because the estate is secure, it may well simply be accessed by way of extending the unique TcpClient category. we have now determined to demonstrate this system right here through extending the TcpClient classification to entry the Socket technique Shutdown(). now we have created the TcpClientShutdown type on the way to do that.
