By Michael J. Donahoo, Kenneth L. Calvert

"TCP/IP sockets in C# is a superb e-book for someone drawn to writing community purposes utilizing Microsoft .Net frameworks. it's a specific blend of good written concise textual content and wealthy conscientiously chosen set of operating examples. For the newbie of community programming, it is a solid beginning ebook; nevertheless pros may also reap the benefits of very good convenient pattern code snippets and fabric on subject matters like message parsing and asynchronous programming."
Adarsh Khare, SDT, .Net Frameworks staff, Microsoft Corporation

The acclaim for the C# language and the .NET framework is ever emerging as a result of its ease of use, the wide classification libraries to be had within the .NET Framework, and the ubiquity of the Microsoft home windows working procedure, to call a couple of benefits. TCP/IP Sockets in C# makes a speciality of the Sockets API, the de facto normal for writing community purposes in any programming language. beginning with basic buyer and server courses that use TCP/IP (the web protocol suite), scholars and practitioners quick research the fundamentals and circulation directly to firsthand event with complicated subject matters together with non-blocking sockets, multiplexing, threads, asynchronous programming, and multicasting. Key community programming innovations comparable to framing, functionality and deadlocks are illustrated via hands-on examples. utilizing a close but transparent, concise technique, this e-book contains various code examples and centred discussions to supply a superb knowing of programming TCP/IP sockets in C#.

*Tutorial-based guide in key sockets programming ideas complemented via a number of code examples all through
*Discussion strikes fast into the C# Sockets API definition and code examples, fascinating if you happen to are looking to get up-to-speed quickly
*Important insurance of "under the hood" information that builders will locate beneficial whilst growing and utilizing a socket or a better point TCP type that makes use of sockets
*Includes end-of-chapter routines to facilitate studying, in addition to pattern code to be had for obtain on the book’s significant other website

Start and finish operations are meant to be symmetrical, and every name to a start process will be matched (at a few aspect) with an finish procedure name. Failure to take action in a long-running application creates an accumulation of nation upkeep for the uncompleted asynchronous calls . . . in different phrases, a reminiscence leak! Let’s examine a few concrete examples. The NetworkStream category comprises asynchronous models of its Write() and Read() tools, applied as BeginWrite(), EndWrite(), BeginRead(), and EndRead(). Let’s have a look at those equipment and think about how they relate to their blockading opposite numbers. The BeginRead() and BeginWrite() equipment take extra arguments and feature a unique go back kind: public override IAsyncResult BeginRead(byte[ ] buffer, int offset, int measurement, AsyncCallback callback, item state); public override IAsyncResult BeginWrite(byte[ ] buffer, int offset, int count number, AsyncCallback callback, item state); the 2 extra arguments are an example of AsyncCallback and an example of item, which are any C# category example (predefined or user-defined). The AsyncCallback type is a delegate that specifies the callback solution to invoke whilst the asynchronous alternative is whole. This category may be instantiated just by passing it the identify of the 118 bankruptcy four: past the fundamentals ■ technique for the callback: AsyncCallback ac = new AsyncCallback(myMethodToCall); :: : public static void myMethodToCall(IAsyncResult end result) { // callback code is going right here } If no callback procedure is needed, this argument might be null (although do not forget that the tip strategy needs to be invoked somewhere). The callback process itself should have the signature public static void (IAsyncResult). The IAsyncResult type might be mentioned in a second. the article argument is just the way to show user-defined info from the caller to the callback. this knowledge may be the NetworkStream or socket type example itself, or a user-defined type that incorporates either the NetworkStream, the byte buffer getting used, and the rest to which the appliance callback process wishes entry. The BeginRead() and BeginWrite() equipment actually have a assorted go back variety: an IAsyncResult example. The IAsyncResult represents the prestige of the asynchronous operation and will be used to ballot or block at the go back of that operation. when you choose to block watching for the operation to accomplish, the IAsyncResult’s AsyncWaitHandle estate encompasses a technique referred to as WaitOne(). Invoking this system will block until eventually the corresponding finish procedure is termed. as soon as the asynchronous operation completes, the callback approach is invoked. The callback procedure gets an IAsyncResult example as a controversy, which has a estate referred to as AsyncState that would comprise an item. This item is identical item that was once handed to the commence strategy, and wishes to be solid to its unique style earlier than getting used. The IAsyncResult example can be used because the argument to the tip name. the top name completes the symmetry of the decision and returns the results of the decision.
