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
