Flex calls WebService2 (Based on. net) and flexwebservice2

There are many methods for flex to access WebService, using"Data/service"The function can automatically generate a proxy class to access WebService. This prevents all data access from being written to the MXML page for reuse. At the same time, you can directly import custom data types to the background, this facilitates parameter passing.

Directly run the code: the WebService Interface

namespace MyNetWebService{    /// <summary>    /// Summary of MyWebService    /// </summary>    [WebService(Namespace = "http://tempuriTemp.org/")]    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]    [System.ComponentModel.ToolboxItem(false)]    // To allow ASP. net ajax to call this Web service from a script, cancel the comments to the downstream.    // [System.Web.Script.Services.ScriptService]    public class MyWebService : System.Web.Services.WebService    {         [WebMethod]        public string HelloWorld()        {            return "Hello World";        }         [WebMethod]        public Model[] GetDetailResult(SearchParameter parmeter, Staff staff)        {            return ModelHelp.GetSaleDetailResult(parmeter, staff);        }    }        }

Add a WebService:

Connection data/service-> Web Service-> wsdl url: Enter the service address (http: // localhost/XXX/MyWebService. asmx? WSDL)

Use"Data/service"Proxy class generated by the function under services:

Imported webService methods and custom types under data/service

Automatically generate a proxy class _ Super_MyWebService.as to access WebService
