flex 訪問WebService的方法有很多種，使用FLEX4中的"數據/服務"功能可以自動生成訪問WebService的代理類,這樣可以避免把所有的數據訪問都寫到MXML頁面上,便於重復利用，同時可以直接導入後台自定義數據類型，方便傳參。
直接上代碼：其中WebService接口

[WebService(Namespace = "http://tempuriTemp.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允許使用 ASP.NET AJAX 從腳本中調用此 Web 服務，請取消對下行的注釋。
// [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服務：
連接數據/服務—>Web服務—>WSDL URL: 填寫服務地址（http://localhost/XXX/MyWebService.asmx?WSDL）
使用FLEX4中的"數據/服務"功能 在services 下生成的代理類：
數據/服務 下 導入了webService的方法 和 自定義類型
