C# WCF学习并创建简单WCF示例

1. 以管理员运行VS 创建WCF服务端项目

2. 覆盖IService1.cs

using System;
using System.ServiceModel;

namespace GettingStartedLib
{
        [ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
        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);
        }
}

3. 覆盖Service1.cs

using System;
using System.ServiceModel;

namespace GettingStartedLib
{
    public class CalculatorService : ICalculator
    {
        public double Add(double n1, double n2)
        {
            double result = n1 + n2;
            Console.WriteLine("Received Add({0},{1})", n1, n2);
            // Code added to write output to the console window.
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Subtract(double n1, double n2)
        {
            double result = n1 - n2;
            Console.WriteLine("Received Subtract({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Multiply(double n1, double n2)
        {
            double result = n1 * n2;
            Console.WriteLine("Received Multiply({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }

        public double Divide(double n1, double n2)
        {
            double result = n1 / n2;
            Console.WriteLine("Received Divide({0},{1})", n1, n2);
            Console.WriteLine("Return: {0}", result);
            return result;
        }
    }
}

4.修改app.config

将第 14 行更改为

将第 17 行更改为
< add baseAddress =“http://localhost:8000/GettingStarted/CalculatorService” />
将第 22 行更改为
< endpoint address="" binding=“wsHttpBinding” contract=“GettingStartedLib.ICalculator”/>

5. 在当前解决方案中新建控制台应用

6. 添加刚刚wcf服务库的引用

7. 创建成功，打开对应网页

8. .net framework创建客户端

using ConsoleApp4.ServiceReference1;
using System;
using System.ServiceModel;

namespace GettingStartedClient
{
    class Program
    {
        static void Main(string[] args)
        {
            //Step 1: Create an instance of the WCF proxy.
            EndpointAddress epAddress = new EndpointAddress("http://localhost:8000/GettingStarted/CalculatorService");
            CalculatorClient client = new CalculatorClient(new WSHttpBinding(), epAddress);

            //CalculatorClient client = new CalculatorClient();

            // Step 2: Call the service operations.
            // 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);

            // Step 3: Close the client to gracefully close the connection and clean up resources.
            Console.WriteLine("\nPress  to terminate the client.");
            Console.ReadLine();
            client.Close();
        }
    }
}

9. 要先运行之前的GettingStarted项目！添加服务引用

右键添加里面有，服务引用

10. 运行成功
