Abstract

The invention discloses a communication multithreading technology which includes the steps of firstly, defining a WCF service contract, and building a WCF service project; secondly, realizing a WCF service, and building a class inheritance WCF service interface; thirdly, defining a delegation class, and declaring at the location of a delegation event; fourthly, starting the WCF service; fifthly, using the delegation event, declaring the class of a WCF service delegation message, and declaring the delegation event of an interface thread; sixthly, guiding into a thread pool, and opening another thread. The communication multithreading technology has the advantages that cross-platform communication can be achieved; coding methods are high in readability and easy to expand; large amount of If-Else (Switch) statement used in a program can be avoided; program stability and stable communication among threads are achieved; program quality and efficiency are increased.

Description

A kind of communication multithreading

Technical field

The present invention relates to a kind of mechanics of communication, what be specifically related to is a kind of communication multithreading.

Background technology

Mechanics of communication:

WCF:Windows Communication Foundation (WCF) is the application development interface of one group of data communication being developed by Microsoft, it is a part for NET framework, started to introduce by NET Framework 3.0, with three major application program development class libraries of Windows Presentation Foundation and Windows Workflow Foundation behavior a new generation's Windows operating system and WinFX.In NET Framework 2.0 and front version, Microsoft has developed Web Service (SOAP with HTTP communicatio), the communications such as the Winsock on NET Remoting (TCP/HTTP/Pipeline communication) and basis are supported, due to the method for designing difference of each communication means, and (for example NET Remoting can develop SOAP also each other mutual plyability, HTTP communication), for developer, different selections has different programming models, and must relearn, allow developer in use have much inconvenience.Simultaneously, Service-Oriented Architecture Based (Service-Oriented Architecture) also starts prevailing in software industry, therefore Microsoft has checked these communication meanss again, and design a unified program development model, provide substantially the most resilient support for data communication, Here it is Windows Communication Foundation.

Trust is a class, it has defined the type of method, the parameter that method can be used as to another method is transmitted, this way that method is dynamically assigned to parameter, can avoid a large amount of If-Else (Switch) of use statements in program, make calling program there is better extensibility simultaneously.

Thread pool is a kind of multithreading processing form, in processing procedure, adds task to queue, then after establishment thread, automatically starts these tasks.Thread pool thread is all background thread. each thread uses the storehouse size of acquiescence, with the priority operation of acquiescence, if and in multiple thread units. certain thread is idle (as waited for certain event) in Managed Code, if thread pool makes all processors keep busy another worker thread of insertion. all thread pool threads all remain busy, but in queue, comprise the work of hang-up, thread pool will create another worker thread but the number of thread exceedes maximal value never over time. and exceeding peaked thread can queue up, but they will wait until after other threads complete and just start.

Summary of the invention

The object of the invention is to overcome the above problem that prior art exists, a kind of many communications multithreading is provided, communication skill is used flexibly, make the simple of Multi-thread Communication reading and writing data change.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:

A kind of communication multithreading, step is as follows:

The contract of step 1) definition WCF service, sets up the engineering of a WCF service, states a contract interface, introduces the attribute of contract definition and interface function, the call back function of definition asynchronous interface;

Step 2) realize WCF service, set up a class and inherit WCF service interface, before class, there is statement, realize interface function, message informing is stated to a synchronous stage signal before to interface, then call callback method by described signal;

Class is entrusted in step 3) definition, states in the place of commit event, and described statement comprises parameter and the title of entrusting Message function;

Step 4) starts WCF service by host's mode, state a WCF service object, then protocol parameter and service parameter are set, and definition bindtype is ICP/IP protocol, and maximum byte number, transmission time-out time, contract class, COS, the wcf address of service of receiving is set;

Step 5) is used commit event, and the class of message is entrusted in statement WCF service, the commit event of statement interface thread;

Step 6) is introduced thread pool, and separately opens a thread, and statement thread also arranges thread parameter.

The invention has the beneficial effects as follows:

1, realize cross-platform communication;

2, code method reading property is strong, easily expansion;

3, can avoid a large amount of If-Else (Switch) of use statements in program;

4, program stability is strong, cross-thread communication robust;

5, in the quality of program and efficiency, be all improved.

Embodiment

Below in conjunction with embodiment, describe the present invention in detail.

A kind of communication multithreading, step is as follows:

The contract of step 1) definition WCF service, sets up the engineering of a WCF service, states a contract interface, introduces the attribute of contract definition and interface function, the call back function of definition asynchronous interface;

Step 2) realize WCF service, set up a class and inherit WCF service interface, before class, there is statement, realize interface function, message informing is stated to a synchronous stage signal before to interface, then call callback method by described signal;

Class is entrusted in step 3) definition, states in the place of commit event, and described statement comprises parameter and the title of entrusting Message function;

Step 4) starts WCF service by host's mode, state a WCF service object, then protocol parameter and service parameter are set, and definition bindtype is ICP/IP protocol, and maximum byte number, transmission time-out time, contract class, COS, the wcf address of service of receiving is set;

Step 5) is used commit event, and the class of message is entrusted in statement WCF service, the commit event of statement interface thread;

Step 6) is introduced thread pool, and separately opens a thread, and statement thread also arranges thread parameter.

Claims (1)

1. a communication multithreading, is characterized in that, step is as follows:

The contract of step 1) definition WCF service, sets up the engineering of a WCF service, states a contract interface, introduces the attribute of contract definition and interface function, the call back function of definition asynchronous interface;

Step 2) realize WCF service, set up a class and inherit WCF service interface, before class, there is statement, realize interface function, message informing is stated to a synchronous stage signal before to interface, then call callback method by described signal;

Class is entrusted in step 3) definition, states in the place of commit event, and described statement comprises parameter and the title of entrusting Message function;

Step 4) starts WCF service by host's mode, state a WCF service object, then protocol parameter and service parameter are set, and definition bindtype is ICP/IP protocol, and maximum byte number, transmission time-out time, contract class, COS, the wcf address of service of receiving is set;
