Recently, Web service needs to be used in project development. I have made a small example of myself to deepen my understanding of Web service.
Concept: Web service is a kind of interface that is proposed to make the information between isolated sites communicate and share with each other. Web service uses uniform, open standards on the Internet, such as HTTP, XML, SOAP (Simple Object Access Protocol), WSDL, and so on, so Web service can be used in any environment that supports these standards (WINDOWS,LINUX). Note: The SOAP protocol, simple Object access Protocal, is an XML-based communication protocol for network information exchange in decentralized and distributed environments. Under this protocol, software components or applications can communicate through the standard HTTP protocol. It is designed to be simple and extensible, which facilitates interoperability between heterogeneous programs and platforms, so that existing applications can be accessed by a wide range of users.
This is the Web service server side MyWeb service.asmx file code:
1 usingSystem;2 usingSystem.Collections.Generic;3 usingsystem.web;4 usingSystem.Web.Services;5 6 /// <summary>7 ///Summary description of MyWebService8 /// </summary>9[WebService (Namespace ="http://tempuri.org/")]Ten[WebServiceBinding (ConformsTo =wsiprofiles.basicprofile1_1)] One Public classMyWebService:System.Web.Services.WebService { A - PublicMyWebService () { - the //If you are using a design component, uncomment the following line - //InitializeComponent (); - } -[WebMethod (Description ="method of summation")] + Public DoubleAddition (DoubleIDoublej) - { + returni +J; A } at[WebMethod (Description ="the method of finding the difference")] - Public DoubleSubtractDoubleIDoublej) - { - returnIJ; - } -[WebMethod (Description ="the method of calculating the product")] in Public DoubleMultiplication (DoubleIDoublej) - { to returnIJ; + } -[WebMethod (Description ="How to find a business")] the Public DoubleDivision (DoubleIDoublej) * { $ if(J! =0) Panax Notoginseng { - returnIJ; the } + Else A { the return 0; + } - } $}
This is the client foreground index.aspx file code:

Parse (Num1.text),Double. Parse (Num2.text)). ToString (); - } + Else if(Selectflag.equals ("-")) A { atResult.text = (Web.subtract (Double. Parse (Num1.text),Double. Parse (Num2.text)). ToString (); - } - Else if(Selectflag.equals ("*")) - { -Result.text = (Web.multiplication (Double. Parse (Num1.text),Double. Parse (Num2.text)). ToString (); - } in Else if(Selectflag.equals ("/")) - { toResult.text = (Web.division (Double. Parse (Num1.text),Double. Parse (Num2.text)). ToString (); + } - } the}In this way, an ASP. NET Web site access is implemented with two integer operations using a Web service service.
