(转)将wcf 以webservice的方式调用

问题:a公司使用wcf 发布服务(.net Framework 3.0 or 3.5),b公司需要使用a公司发布的服务 ,但b公司目前阶段只使用.net Framework2.0(.net Framework 2.0不支持wcf),如果要调用a公司wcf 服务,那怎么办呢?

一、先上wcf 代码(这里懒得写了,借用microsoft公司发布的wcf  samples):

namespace Microsoft.ServiceModel.Samples
{
    // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.
    [ServiceContract, XmlSerializerFormat]
    public interface ICalculator
    {
        [OperationContract]
        double Add(double n1, double n2);
        [OperationContract]
        double Subtract(double n1, double n2);
        [OperationContract]
        double Multiply(double n1, double n2);
        [OperationContract]
        double Divide(double n1, double n2);
    }     public class CalculatorService : ICalculator
        {
            public double Add(double n1, double n2)
            {
                return n1 + n2;
            }             public double Subtract(double n1, double n2)
            {
                return n1 - n2;
            }             public double Multiply(double n1, double n2)
            {
                return n1 * n2;
            }             public double Divide(double n1, double n2)
            {
                return n1 / n2;
            }
        }
}

配置文件:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service
          name="Microsoft.ServiceModel.Samples.CalculatorService"
          behaviorConfiguration="CalculatorServiceBehavior">
        <endpoint address=""
                  binding="basicHttpBinding"
                  contract="Microsoft.ServiceModel.Samples.ICalculator" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="CalculatorServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

运行,记录服务地址。

二、使用wsdl工具将wcf service生成asp.net webservice方式。

start --->运行--->cmd --->cd C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin  回车。

输入wsdl 服务地址。例(wsdl http://localhost:8571/Service1.svc )便生成相应的类似asp.net webservice代理类的文件。文件地址亦在上面bin中。

新建Console application (net Framework 2.0),添加刚刚生成的代理类。调用:

调用代码:

 class Client
    {
        static void Main()
        {
            // Create a client to the CalculatorService
            using (CalculatorService client = new CalculatorService())
            {
                // Call the Add service operation.
                double value1 = 100.00D;
                double value2 = 15.99D;
                double result = client.Add(value1, value2);
                Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);                 // Call the Subtract service operation.
                value1 = 145.00D;
                value2 = 76.54D;
                result = client.Subtract(value1, value2);
                Console.WriteLine("Subtract({0},{1}) = {2}", value1, value2, result);                 // Call the Multiply service operation.
                value1 = 9.00D;
                value2 = 81.25D;
                result = client.Multiply(value1, value2);
                Console.WriteLine("Multiply({0},{1}) = {2}", value1, value2, result);                 // Call the Divide service operation.
                value1 = 22.00D;
                value2 = 7.00D;
                result = client.Divide(value1, value2);
                Console.WriteLine("Divide({0},{1}) = {2}", value1, value2, result);             }             Console.WriteLine();
            Console.WriteLine("Press <ENTER> to terminate client.");
            Console.ReadLine();
        }
    }

配置文件:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="CalculatorServiceAddress" value="http://localhost:8571/Service1.svc"/>
  </appSettings>
</configuration>

运行,即可成功调用。
