範例

以下程式碼範例是由 Wsdl.exe Math 為 XML Web 服務產生的代理類別。 代理類由 SoapHttpClientProtocol衍生而來，而 又由抽象 WebClientProtocol 類衍生而來。

 using System;

 public class MyMath {
    
    [ WebMethod ]
    public int Add(int num1, int num2) {
        return num1+num2;
    }
 }

<%@ WebService Language="VB" Class="MyMath"%>

    <WebMethod()> _
    Public Function Add(num1 As Integer, num2 As Integer) As Integer
        Return num1 + num2
    End Function 'Add
End Class 'Math

備註

如果你正在建置一個 XML Web 服務客戶端，那麼必須為 XML Web 服務建立一個間接或直接衍生的 WebClientProtocol 代理類別。 當 XML Web 服務客戶端使用 SOAP 呼叫時，代理類別必須從 SoapHttpClientProtocol衍生出 ，而 又從 衍生出 HttpWebClientProtocol。 HttpWebClientProtocol，又從 推導出 WebClientProtocol。

要與 XML Web 服務通訊，請建立一個代理類別，該類別可間接或直接衍生於 WebClientProtocol 你想呼叫的 XML Web 服務。 與其手動建立代理類別，不如使用 Web Services Description Language 工具（Wsdl.exe）為特定 XML Web 服務的服務描述建立代理類別。 當為 SOAP 協定產生代理類別時，透過該 Invoke 方法同步呼叫 XML Web 服務方法，而非同步呼叫則使用 BeginInvoke 該方法與 方法 EndInvoke 。

給繼承者的注意事項

當你覆寫這個類別時，可以在派生類別中引入特定類型的 XML Web 服務方法。 這些方法會擷取參數並呼叫基底類別，來執行與 XML Web 服務通訊的工作。 若引入的方法為非同步，則呼叫該 BeginInvoke(String, Object[], AsyncCallback, Object) 方法與該 EndInvoke(IAsyncResult) 方法。 如果引入的方法是同步的，則呼叫該 Invoke(String, Object[]) 方法。 覆寫後的建構子通常將屬性設定 Url 為 XML Web 服務方法的 URL。
