wcf入门示例

msdn上有篇很好的wcf入门例子。很适合初学者。一步一步教你如何创建wcf程序。
这篇文章其实也就是把msdn上的代码组装了下。
首先创建服务器端程序。代码如下：
接口：ICalculator,定义了加减乘除四个方法add,subtract,multiply,divide。

 1using System;
 2using System.Collections.Generic;
 3using System.Linq;
 4using System.Text;
 5using System.ServiceModel;
 6
 7namespace Microsoft.ServiceModel.Samples
 8{
 9    [ServiceContractAttribute]
10    interface ICalculator
11    {
12        [OperationContractAttribute]
13        double Add(double a,double b);
14        [OperationContractAttribute]
15        double Subtract(double a, double b);
16        [OperationContractAttribute]
17        double Multiply(double a, double b);
18        [OperationContractAttribute]
19        double Divide(double a, double b);
20
21    }
22}
23

接口实现类：CalculatorService

 1using System;
 2using System.Collections.Generic;
 3using System.Linq;
 4using System.Text;
 5
 6namespace Microsoft.ServiceModel.Samples
 7{
 8    class CalculatorService:ICalculator
 9    {
10
11        ICalculator 成员#region ICalculator 成员
12
13        public double Add(double a, double b)
14        {
15            double result = a + b;
16            Console.WriteLine("Received Add({0},{1})",a,b);
17            Console.WriteLine("Return: {0}",result);
18            return result;
19        }
20
21        public double Subtract(double a, double b)
22        {
23            double result = a - b;
24            Console.WriteLine("Received Subtract({0},{1})",a,b);
25            Console.WriteLine("Return :{0}",result);
26            return result;
27        }
28
29        public double Multiply(double a, double b)
30        {
31            double result = a * b;
32            Console.WriteLine("Received Multiply({0},{1})",a,b);
33            Console.WriteLine("Return :{0}",result);
34            return result;
35        }
36
37        public double Divide(double a, double b)
38        {
39            double result = a / b;
40            Console.WriteLine("Received Divice({0},{1})",a,b);
41            Console.WriteLine("Return :{0}",result);
42            return result;
43        }
44
45        #endregion
46    }
47}

主程序代码：

 1using System;
 2using System.Collections.Generic;
 3using System.Linq;
 4using System.Text;
 5using System.ServiceModel;
 6using System.ServiceModel.Description;
 7
 8namespace Microsoft.ServiceModel.Samples
 9{
10    class Program
11    {
12        static void Main(string[] args)
13        {
14            Uri baseAdderess = new Uri("http://localhost:8000/ServicesModelSamples/Service");
15            ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAdderess);
16            selfHost.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "CalculatorService");
17            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
18            smb.HttpGetEnabled = true;
19            selfHost.Description.Behaviors.Add(smb);
20            selfHost.Open();
21            Console.WriteLine("The service is ready");
22            Console.WriteLine("Please press <Enter> to terminate service ");
23            Console.ReadLine();
24
25        }
26    }
27}

创建客户端:添加服务引用

 1using System;
 2using System.Collections.Generic;
 3using System.Linq;
 4using System.Text;
 5using System.ServiceModel;
 6using Client.ServiceCalculator;
 7
 8namespace Client
 9{
10    class Program
11    {
12        static void Main(string[] args)
13        {
14            EndpointAddress epAddress = new EndpointAddress("http://localhost:8000/ServiceModelSamples/Service/CalculatorService");
15            CalculatorClient client = new CalculatorClient();
16            //Add
17            double a = 100.00d;
18            double b = 15.99d;
19            double result = client.Add(a, b);
20            Console.WriteLine("Add:{0} + {1} = {2}",a,b,result);
21            //Substract
22            a = 100.00d;
23            b = 15.99d;
24            result = client.Subtract(a, b);
25            Console.WriteLine("Sub:{0} + {1} = {2}",a,b,result);
26            //Multiply
27            a = 9.00d;
28            b = 81.25d;
29            result = client.Multiply(a, b);
30            Console.WriteLine("Mul:{0} + {1} = {2}",a,b,result);
31            //Divide
32            a = 100.00d;
33            b = 15.99d;
34            result = client.Divide(a, b);
35            Console.WriteLine("Div:{0} + {1} = {2}",a,b,result);
36
37        }
38    }
39}
