flex 调用WebService2(基于.net)

    flex 访问WebService的方法有很多种，使用FLEX4中的"数据/服务"功能可以自动生成访问WebService的代理类,这样可以避免把所有的数据访问都写到MXML页面上,便于重复利用，同时可以直接导入后台自定义数据类型，方便传参。

    直接上代码：其中WebService接口

namespace MyNetWebService

{

    /// <summary>

    /// MyWebService 的摘要说明

    /// </summary>

    [WebService(Namespace = "http://tempuriTemp.org/")]

    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [System.ComponentModel.ToolboxItem(false)]

    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。

    // [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);

        }

    }        

}

添加WebService服务：

  连接数据/服务—>Web服务—>WSDL URL:  填写服务地址（http://localhost/XXX/MyWebService.asmx?WSDL） 

使用FLEX4中的"数据/服务"功能 在services 下生成的代理类：

        

数据/服务 下 导入了webService的方法 和 自定义类型
