WCF快速上手

需求：在同一台机子上，有一个B/S程序，和一个C/S程序(不要问为什么，事实就是这样)，B/S程序需要主动和C/S程序通信(C/S程序主动与B/S程序通信的情况这里暂不讨论)。

下面以最快的速度写一个B/S程序和一个C/S程序实现，具体细节不解释，自己翻书看去。

一、建了两个工程，如下图所示：

二、先看C/S程序，跑起来就是这样的，如下图所示(简单吧)：

程序结构如下图：

WCF的接口WCFServer、数据结构DataStruct、Winform程序Client

IClientServer：

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Threading.Tasks;
using DataStruct;

namespace WCFServer
{
    [ServiceContract]
    public interface IClientServer
    {
        [OperationContract]
        TestData Test(string param);
    }
}

View Code

ClientServer：

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Threading.Tasks;
using DataStruct;

namespace WCFServer
{
    [ServiceBehavior()]
    public class ClientServer : IClientServer
    {
        /// <summary>
        /// 测试
        /// </summary>
        public TestData Test(string param)
        {
            TestData data = new TestData();
            data.Name = param;
            data.Code = "0101";
            return data;
        }
    }
}

View Code

TestData：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;

namespace DataStruct
{
    [DataContract]
    public class TestData
    {
        [DataMember]
        public string Name { get; set; }

        [DataMember]
        public string Code { get; set; }
    }
}

Form1.cs：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using WCFServer;

namespace CSServer
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            OpenClientServer();
        }

        /// <summary>
        /// 启动服务
        /// </summary>
        private void OpenClientServer()
        {
            WSHttpBinding wsHttp = new WSHttpBinding();
            wsHttp.MaxBufferPoolSize = 524288;
            wsHttp.MaxReceivedMessageSize = 2147483647;
            wsHttp.ReaderQuotas.MaxArrayLength = 6553600;
            wsHttp.ReaderQuotas.MaxStringContentLength = 2147483647;

            wsHttp.ReaderQuotas.MaxDepth = 6553600;

            wsHttp.CloseTimeout = new TimeSpan(0, 1, 0);
            wsHttp.OpenTimeout = new TimeSpan(0, 1, 0);
            wsHttp.ReceiveTimeout = new TimeSpan(0, 10, 0);
            wsHttp.SendTimeout = new TimeSpan(0, 10, 0);
            wsHttp.Security.Mode = SecurityMode.None;

            Uri baseAddress = new Uri("http://127.0.0.1:9999/clientserver");
            ServiceHost host = new ServiceHost(typeof(ClientServer), baseAddress);

            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            host.Description.Behaviors.Add(smb);

            ServiceBehaviorAttribute sba = host.Description.Behaviors.Find<ServiceBehaviorAttribute>();
            sba.MaxItemsInObjectGraph = 2147483647;

            host.AddServiceEndpoint(typeof(IClientServer), wsHttp, "");

            host.Open();
        }
    }

C/S程序跑起来就OK了。

三、B/S程序

程序结构如下图：

WCF的接口DataService、Web程序

DataService需要引用数据结构DataStruct和WCFServer，是C/S程序编译后的dll拿过来的，Web需要引用DataStruct，如下图：

ClientServer：

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Text;
using System.Threading.Tasks;
using DataStruct;
using WCFServer;

namespace DataService
{
    public class ClientServer
    {
        ChannelFactory<IClientServer> channelFactory;
        IClientServer proxy;

        /// <summary>
        /// 创建连接客户终端WCF服务的通道
        /// </summary>
        public void CreateChannel()
        {
            string url = "http://127.0.0.1:9999/clientserver";
            WSHttpBinding wsHttp = new WSHttpBinding();
            wsHttp.MaxBufferPoolSize = 524288;
            wsHttp.MaxReceivedMessageSize = 2147483647;
            wsHttp.ReaderQuotas.MaxArrayLength = 6553600;
            wsHttp.ReaderQuotas.MaxStringContentLength = 2147483647;
            wsHttp.ReaderQuotas.MaxBytesPerRead = 6553600;
            wsHttp.ReaderQuotas.MaxDepth = 6553600;
            wsHttp.ReaderQuotas.MaxNameTableCharCount = 6553600;
            wsHttp.SendTimeout = new TimeSpan(0, 10, 0);
            wsHttp.Security.Mode = SecurityMode.None;

            channelFactory = new ChannelFactory<IClientServer>(wsHttp, url);
            foreach (OperationDescription op in channelFactory.Endpoint.Contract.Operations)
            {
                DataContractSerializerOperationBehavior dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>() as DataContractSerializerOperationBehavior;

                if (dataContractBehavior != null)
                {
                    dataContractBehavior.MaxItemsInObjectGraph = 2147483647;
                }
            }
        }

        /// <summary>
        /// 测试
        /// </summary>
        public TestData Test(string param)
        {
            proxy = channelFactory.CreateChannel();

            try
            {
                return proxy.Test(param);
            }
            catch (Exception ex)
            {
                return null;
            }
            finally
            {
                (proxy as ICommunicationObject).Close();
            }
        }
    }
}

View Code

TestController：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DataService;
using DataStruct;

namespace BSClient.Controllers
{
    public class TestController : Controller
    {

        public ActionResult Index()
        {
            ClientServer client = new ClientServer();
            client.CreateChannel();
            ViewData["data"] = client.Test("ABCD");

            return View();
        }

    }
}

View Code

Index.cshtml：

@using DataStruct;
@{
    ViewBag.Title = "Index";
    TestData data = ViewData["data"] as TestData;
    if (data == null) { data = new TestData(); }
}

<h2>Index</h2>

<h2>@data.Name</h2>
<h2>@data.Code</h2>

先启动C/S程序，再启动B/S程序，B/S的运行结果如下图所示：

上面以最快的速度写了一个WCF的简单的Demo，程序跑起来了，后面的再慢慢学吧。
