示例

下面的示例是一个由 wsdl.exe 实用工具为Math以下 XML Web service 生成的代理类。The following example is a proxy class generated by the Wsdl.exe utility for the Math XML Web service below. 代理类派生HttpPostClientProtocol自抽象类, 后者派生自抽象HttpSimpleClientProtocol类。The proxy class derives from HttpPostClientProtocol, which derives from the abstract HttpSimpleClientProtocol class.

 using System.Web.Services;
 using System;
 
 public class Math {
      [ WebMethod ]
      public int Add(int num1, int num2) {
          return num1+num2;
          }
 }

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

注解

如果 XML Web service 客户端使用 HTTP POST 协议, 则默认情况下, 使用 URL 编码规则在 HTTP 正文中对参数进行编码, 并使用纯 XML 来响应。When an XML Web service client uses the HTTP-POST protocol, by default parameters are encoded within the HTTP body using URL encoding rules and uses plain XML for the response. 此协议使用派生自MimeFormatter的类将参数编码并将值返回到标准的 MIME 格式。This protocol uses classes that derive from MimeFormatter to encode parameters and return values into standard MIME formats. 在服务说明中指定要使用的编码器。The encoders to use are specified in the service description.

如果使用 ASP.NET 生成 XML Web service 客户端, 则WebClientProtocol需要为要调用的 XML Web service 创建间接或直接派生的代理类。If you are building an XML Web service client using ASP.NET, then a proxy class deriving indirectly or directly from WebClientProtocol needs to be created for the XML Web service you want to call. 当 XML Web service 客户端使用 HTTP 调用时, 派生代理类HttpSimpleClientProtocol, 后者反过来派生自。 WebClientProtocolWhen the XML Web service client is calling using HTTP, derive the proxy class HttpSimpleClientProtocol, which in turn derives from WebClientProtocol.

HttpGetClientProtocolHttpPostClientProtocol派生自HttpSimpleClientProtocol, 它提供对使用 HTTP GET 和 http POST 调用 XML Web service 方法的支持。HttpGetClientProtocol and HttpPostClientProtocol derive from HttpSimpleClientProtocol, providing the support for calling an XML Web service method using HTTP-GET and HTTP-POST respectively. 使用 SOAP 调用 XML Web service 的客户端应派生SoapHttpClientProtocol自。Clients calling an XML Web service using SOAP should derive from SoapHttpClientProtocol.
