silverlight插件_关于Silverlight跨域访问安全性问题解决方法

【www.bbyears.com--WebService】

下面是服务的部分代码：

 代码如下

 ///

    /// Summary description for WeatherWebService
    ///

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class WeatherWebService : System.Web.Services.WebService
    {

        ///

        /// 获取第三方ws支持的指定省份下的城市名称
        ///

        ///
        ///
        [WebMethod]
        public string[] GetSupportCity(string provinceName)
        {
            var service = new WS.WeatherWebServiceSoapClient();
            return service.getSupportCity(provinceName);
        }
    }

Step2:在SL项目中引用本地服务
直接添加本地的WebService引用，然后在程序中调用，下面是部分代码：

 代码如下

 private void button1_Click(object sender, RoutedEventArgs e)
        {
            var service = new LocalServiceReference.WeatherWebServiceSoapClient();
            service.GetSupportCityCompleted+=new EventHandler(service_GetSupportCityCompleted);
            service.GetSupportCityAsync("安徽");
        }

        void service_GetSupportCityCompleted(object sender, GetSupportCityCompletedEventArgs e)
        {
            this.ListContent.ItemsSource = e.Result;
        }Step3:查看结果

 

先看直接访问第三方服务的截图：

 

 

这是使用本地服务作为中介的结果：
