Linq to sql（十）：分层构架的例子（三）

WCF服务端与客户端

打开Host项目中的Program.cs，使用下面的代码来实现WCF的服务端：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.ServiceModel;

using Service;

using Contract;

namespace Host

{

class Program

{

static void Main(string[] args)

{

Uri uri = new Uri("net.tcp://localhost:8080/DataAccessService");

using (ServiceHost sh = new ServiceHost(typeof(DataAccess), uri))

{

NetTcpBinding ctb = new NetTcpBinding();

sh.AddServiceEndpoint(typeof(IDataAccess), ctb, string.Empty);

sh.Opened += delegate { Console.WriteLine("服务已经启动"); };

sh.Open();

Console.ReadLine();

}

在WebSite项目中的App_Code文件夹下创建一个用户调用服务的类，GetService.cs：

using System;

using System.Data;

using System.Configuration;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Xml.Linq;

using Contract;

using System.ServiceModel.Description;

using System.ServiceModel;

public class GetService

{

public static IDataAccess GetDataAccessService()

{

ServiceEndpoint sep = new ServiceEndpoint(ContractDescription.GetContract(typeof(IDataAccess)),

new NetTcpBinding(),

new EndpointAddress("net.tcp://localhost:8080/DataAccessService"));

ChannelFactory<IDataAccess> cf = new ChannelFactory<IDataAccess>(sep);

return cf.CreateChannel();

}
