The basic concept of WebService

WebService the simple point of view of a name is a Web-based service that follows the HTTP protocol like a normal web program, receiving requests to respond to external programs and implementing remote calls. The data used by WebService is XML-formatted, so it is also called XML WebService. The current standard WebService uses the SOAP protocol in the data format (the SOAP protocol is actually a text protocol based on the XML Encoding specification), which is described using a WSDL file and registered with UDDI. (The specific concept can be Google's)

Creation of WebService

Web project Project New project, add a Web service

After adding the code as follows, are automatically generated (Hellworld seems to be the world will never be outdated)

<summary>    ///Myfirstwebservice Summary description///</summary> [WebService (Namespace = "/http// tempuri.org/")]    [webservicebinding (ConformsTo = wsiprofiles.basicprofile1_1)]    [ System.ComponentModel.ToolboxItem (false)]    //To allow the use of ASP. NET AJAX to invoke this Web service from a script, uncomment the following line.     //[System.Web.Script.Services.ScriptService] public    class Myfirstwebservice: System.Web.Services.WebService    {        [WebMethod] public        string HelloWorld ()        {            return ' Hello World ";        }    }

Publishing sites, new computers, installed VS2012, publishing projects and VS2010, publishing project projects, adding Web sites to local IIS, port setting is 7025.

Call of WebService

Create a new console program and add a service reference, such as:

Define the namespace yourself, and the next call is simple, and the code is as follows:

Class program    {        static void Main (string[] args)        {            SFM. Myfirstwebservicesoapclient Web = new SFM. Myfirstwebservicesoapclient ();            Console.WriteLine (web. HelloWorld ());            Console.readkey ();        }    }
