Silverlight 动态调用 WebService

1. 配置 IIS 绑定 IP地址

2. 在 SL 中引用 WebService

3. 在需要调用 WebService 的地方写下列代码:

WCF :

WCF

BasicHttpBinding basicBinding = new BasicHttpBinding();

CustomBinding binding = new CustomBinding(basicBinding);

BindingElement binaryElement = new BinaryMessageEncodingBindingElement();

// 删除原来 Elements 集合内的 TextMessageEncodingBindingElement

binding.Elements.Remove(binding.Elements[0]);

// 添加 BinaryMessageEncodingBindingElement

binding.Elements.Insert(0, binaryElement);

14

15// wcf 地址

16

17EndpointAddress endPoint = new EndpointAddress("http://172.168.1.100/DynamicInvokeWCF.Web/DynWCF.svc");

18

19// 创建 wcf 客户端

20

DynWCFClient client = (DynWCFClient)Activator.CreateInstance(typeof(DynWCFClient), binding, endPoint);

client.DoWorkCompleted += new EventHandler<DoWorkCompletedEventArgs>(client_DoWorkCompleted);

client.DoWorkAsync();

传统 WebService:

WebService

1BasicHttpBinding basicBinding = new BasicHttpBinding();

2

3CustomBinding binding = new CustomBinding(basicBinding);

4

5BindingElement binaryElement = new BinaryMessageEncodingBindingElement();

6

7EndpointAddress endPoint = new EndpointAddress("http://172.168.1.100/DynamicInvokeWCF.Web/Asmx.asmx");

8

9AsmxSoapClient client = (AsmxSoapClient)Activator.CreateInstance(typeof(AsmxSoapClient), binding, endPoint);

10

11client.HelloWorldCompleted += new EventHandler<HelloWorldCompletedEventArgs>(client_HelloWorldCompleted);

12

13client.HelloWorldAsync();

14

15

这样就可以动态的调用 webservice 了. 完全不需要 ServiceReferences.ClientConfig 文件了.
