Exemplos

O exemplo seguinte é uma classe proxy gerada por Wsdl.exe para o Math serviço Web XML abaixo. A classe proxy deriva de HttpGetClientProtocol, que deriva da classe abstrata HttpSimpleClientProtocol .

O exemplo seguinte é o Math serviço Web XML, a partir do qual a classe proxy acima foi criada.

<%@ WebService Language="C#" Class="Math"%>
 using System.Web.Services;
 using System;
 
 public class Math {
      [ WebMethod ]
      public int Add(int num1, int num2) {
          return num1+num2;
          }
 }

<%@ WebService Language="VB" Class="Math"%>
Imports System.Web.Services
Imports System

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

Observações

Quando um cliente de serviço Web XML utiliza o protocolo HTTP-GET, os parâmetros são codificados dentro da URL e a resposta é devolvida em XML simples.

Se estiver a construir um cliente de serviço Web XML usando ASP.NET, então é necessário criar uma classe proxy derivada indiretamente ou diretamente de WebClientProtocol para o serviço Web XML que pretende chamar. Quando o cliente do serviço Web XML chama o serviço Web XML usando HTTP, derive a classe proxy a partir de HttpSimpleClientProtocol, que por sua vez deriva de WebClientProtocol.

HttpGetClientProtocol e HttpPostClientProtocol derivam de HttpSimpleClientProtocol, fornecendo suporte para chamar um método de serviço Web XML usando os protocolos HTTP-GET e HTTP-POST, respetivamente. Clientes que chamam um serviço Web XML usando SOAP devem derivar de SoapHttpClientProtocol.

Para detalhes sobre a construção de uma classe proxy, consulte Criação de um Proxy de Serviço Web XML.
