一、代码结构：

二、数据实体类：


using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;
namespace DataStruct
{
 /// <summary>
 /// 测试数据实体类
 /// </summary>
 [DataContract]
 public class TestData
 {
  [DataMember]
  public double X { get; set; }
  [DataMember]
  public double Y { get; set; }
 }
}

三、服务端服务接口和实现：

接口：


using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Threading.Tasks;
using DataStruct;
namespace WCFServer
{
 /// <summary>
 /// 服务接口
 /// </summary>
 [ServiceContract]
 public interface IClientServer
 {
  /// <summary>
  /// 计算(测试方法)
  /// </summary>
  [OperationContract]
  double Calculate(TestData data);
 }
}

实现：


using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Threading.Tasks;
using DataStruct;
namespace WCFServer
{
 /// <summary>
 /// 服务实现
 /// </summary>
 [ServiceBehavior()]
 public class ClientServer : IClientServer
 {
  /// <summary>
  /// 计算(测试方法)
  /// </summary>
  public double Calculate(TestData data)
  {
   return Math.Pow(data.X, data.Y);
  }
 }
}

四、服务端启动服务：


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 Utils;
using WCFServer;
namespace 服务端
{
 public partial class Form1 : Form
 {
  public Form1()
  {
   InitializeComponent();
  }
  private void Form1_Load(object sender, EventArgs e)
  {
   BackWork.Run(() =>
   {
    OpenClientServer();
   }, null, (ex) =>
   {
    MessageBox.Show(ex.Message);
   });
  }
  /// <summary>
  /// 启动服务
  /// </summary>
  private void OpenClientServer()
  {
   NetNamedPipeBinding wsHttp = new NetNamedPipeBinding();
   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.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 = NetNamedPipeSecurityMode.None;
   Uri baseAddress = new Uri("net.pipe://localhost/pipeName1");
   ServiceHost host = new ServiceHost(typeof(ClientServer), baseAddress);
   ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
   host.Description.Behaviors.Add(smb);
   ServiceBehaviorAttribute sba = host.Description.Behaviors.Find<ServiceBehaviorAttribute>();
   sba.MaxItemsInObjectGraph = 2147483647;
   host.AddServiceEndpoint(typeof(IClientServer), wsHttp, "");
   host.Open();
  }
 }
}

五、客户端数据实体类和服务接口类与服务端相同

六、客户端服务实现：


using DataStruct;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Text;
using System.Threading.Tasks;
using WCFServer;
namespace DataService
{
 /// <summary>
 /// 服务实现
 /// </summary>
 public class ClientServer : IClientServer
 {
  ChannelFactory<IClientServer> channelFactory;
  IClientServer proxy;
  public ClientServer()
  {
   CreateChannel();
  }
  /// <summary>
  /// 创建连接客户终端WCF服务的通道
  /// </summary>
  public void CreateChannel()
  {
   string url = "net.pipe://localhost/pipeName1";
   NetNamedPipeBinding wsHttp = new NetNamedPipeBinding();
   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 = NetNamedPipeSecurityMode.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>
  /// 计算(测试方法)
  /// </summary>
  public double Calculate(TestData data)
  {
   proxy = channelFactory.CreateChannel();
   try
   {
    return proxy.Calculate(data);
   }
   catch (Exception ex)
   {
    throw ex;
   }
   finally
   {
    (proxy as ICommunicationObject).Close();
   }
  }
 }
}

七、客户端调用服务接口：


using DataService;
using DataStruct;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Utils;
using WCFServer;
namespace 客户端
{
 public partial class Form1 : Form
 {
  public Form1()
  {
   InitializeComponent();
  }
  //测试1
  private void button1_Click(object sender, EventArgs e)
  {
   button1.Enabled = false;
   txtSum.Text = string.Empty;
   IClientServer client = new ClientServer();
   double num1;
   double num2;
   double sum = 0;
   if (double.TryParse(txtNum1.Text, out num1) && double.TryParse(txtNum2.Text, out num2))
   {
    DateTime dt = DateTime.Now;
    BackWork.Run(() =>
    {
     sum = client.Calculate(new TestData(num1, num2));
    }, () =>
    {
     double time = DateTime.Now.Subtract(dt).TotalSeconds;
     txtTime.Text = time.ToString();
     txtSum.Text = sum.ToString();
     button1.Enabled = true;
    }, (ex) =>
    {
     button1.Enabled = true;
     MessageBox.Show(ex.Message);
    });
   }
   else
   {
    button1.Enabled = true;
    MessageBox.Show("请输入合法的数据");
   }
  }
  //测试2
  private void button2_Click(object sender, EventArgs e)
  {
   button2.Enabled = false;
   txtSum.Text = string.Empty;
   IClientServer client = new ClientServer();
   double num1;
   double num2;
   double sum = 0;
   if (double.TryParse(txtNum1.Text, out num1) && double.TryParse(txtNum2.Text, out num2))
   {
    DateTime dt = DateTime.Now;
    BackWork.Run(() =>
    {
     for (int i = 0; i < 1000; i++)
     {
      sum = client.Calculate(new TestData(num1, num2));
     }
    }, () =>
    {
     double time = DateTime.Now.Subtract(dt).TotalSeconds;
     txtTime.Text = time.ToString();
     txtSum.Text = sum.ToString();
     button2.Enabled = true;
    }, (ex) =>
    {
     button2.Enabled = true;
     MessageBox.Show(ex.Message);
    });
   }
   else
   {
    button2.Enabled = true;
    MessageBox.Show("请输入合法的数据");
   }
  }
 }
}

八、工具类BackWork类：


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
/**
 * 使用方法：
BackWork.Run(() => //DoWork
{
}, () => //RunWorkerCompleted
{
}, (ex) => //错误处理
{
});
*/
namespace Utils
{
 /// <summary>
 /// BackgroundWorker封装
 /// 用于简化代码
 /// </summary>
 public class BackWork
 {
  /// <summary>
  /// 执行
  /// </summary>
  /// <param name="doWork">DoWork</param>
  /// <param name="workCompleted">RunWorkerCompleted</param>
  /// <param name="errorAction">错误处理</param>
  public static void Run(Action doWork, Action workCompleted, Action<Exception> errorAction)
  {
   bool isDoWorkError = false;
   Exception doWorkException = null;
   BackgroundWorker worker = new BackgroundWorker();
   worker.DoWork += (s, e) =>
   {
    try
    {
     doWork();
    }
    catch (Exception ex)
    {
     isDoWorkError = true;
     doWorkException = ex;
    }
   };
   worker.RunWorkerCompleted += (s, e) =>
   {
    if (!isDoWorkError)
    {
     try
     {
      if (workCompleted != null) workCompleted();
     }
     catch (Exception ex)
     {
      errorAction(ex);
     }
    }
    else
    {
     errorAction(doWorkException);
    }
   };
   worker.RunWorkerAsync();
  }
 }
}
