做這分5部來講解創建一個最基本的基於B/S構架的WCF應用。服務是根據輸入的兩個數字，返回這兩個數字的加減乘除運算結果。
第一步：定義WCF服務契約（創建項目，加入引用，定義Interface）
第二部：引入WCF服務契約（添加具體服務函數）
第三部：構架WCF服務，運行WCF服務（添加Uri,定義服務對象地址，運行服務）
第四部：利用工具訪問服務，自動生成WCF服務代理的代碼文件
第五部：配置一個簡單的WCF客戶端（用客戶端引入服務代理，通過服務代理來訪問服務）
第六部：運行程序
先建立一個解決方案。
在這個解決方案下面建立一個叫做Server的控制檯應用項目，再建立一個叫做Client的控制檯應用項目。
分別給每一個項目添加引用到System.ServiceModel
編輯每個項目下面的Program.cs
using System;
using System.ServiceModel;
using System.ServiceModel.Description;
namespace Microsoft.ServiceModel.Samples
{
// Define a service contract.
[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);
}
// Service class that implements the service contract.
// Added code to write output to the console window.
public class CalculatorService : ICalculator
{
public double Add(double n1, double n2)
{
double result = n1 + n2;
Console.WriteLine("Received Add({0},{1})", n1, n2);
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;
}
}
class Program
{
static void Main(string[] args)
{
// Step 1 of the address configuration procedure: Create a URI to serve as the base address.
Uri baseAddress = new Uri("http://localhost:8000/ServiceModelSamples/Service");
// Step 1 of the hosting procedure: Create ServiceHost
ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAddress);
try
{
// Step 3 of the hosting procedure: Add a service endpoint.
selfHost.AddServiceEndpoint(
typeof(ICalculator),
new WSHttpBinding(),
"CalculatorService");
// Step 4 of the hosting procedure: Enable metadata exchange.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);
// Step 5 of the hosting procedure: Start (and then stop) the service.
selfHost.Open();
Console.WriteLine("The service is ready.");
Console.WriteLine("Press <ENTER> to terminate service.");
Console.WriteLine();
Console.ReadLine();
// Close the ServiceHostBase to shutdown the service.
selfHost.Close();
}
catch (CommunicationException ce)
{
Console.WriteLine("An exception occurred: {0}", ce.Message);
selfHost.Abort();
}
}
}
}
服務端創建好了以後，就可以試運行了。
這時候可以用微軟提供的命令行工具訪問這個服務，生成服務代理 app.config 和 generatedProxy.cs兩個文件。
這時候可以用微軟提供的命令行工具訪問這個服務，生成服務代理 app.config 和 generatedProxy.cs兩個文件。
PATH=C:/WINDOWS/Microsoft.NET/Framework/v3.5
DataSvcUtil.exe /language:csharp /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceModelSamples/service
注意：實在server運行的時候，生成包裝類。
當然，如果是已經運行的服務，可以使用VS引用就行了。
把這兩個文件添加到客戶端項目裏去。
現在就可以編輯客戶端代碼了。
using System;
using System.Collections.Generic;
using System.Text;
using System.ServiceModel;
namespace ServiceModelSamples
{
class Client
{
static void Main()
{
//Step 1: Create an endpoint address and an instance of the WCF Client.
EndpointAddress epAddress = new EndpointAddress("http://localhost:8000/ServiceModelSamples/Service/CalculatorService");
CalculatorClient client = new CalculatorClient(new WSHttpBinding(), epAddress);
// 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: Closing the client gracefully closes the connection and cleans up resources.
client.Close();
Console.WriteLine();
Console.WriteLine("Press <ENTER> to terminate client.");
Console.ReadLine();
}
}
}
每一個細節都包含在上面的這兩個Program.cs文件中了，你大概看一下就會懂。比院子裏大多數教材說得都清晰，特別適合像我一樣愛刨根問底的初學者。:)
最後編譯程序，試運行。（兩個都是命令行程序，直接到那個編譯好的目錄裏去找那個exe文件運行，先運行服務，再運行客戶端）。
