WCF深入学习_并发管理(六)

一.实例说明
(6.Instance mode = Single and Concurrency = Multiple)实例模式'Single'与并发'Multiple'。

In this combination one WCF service instance is created for serve all WCF clients. All request are served using multiple / different

threads.

二.代码分析

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Description;
using System.Threading;
namespace ClassLibrary1
{
    [ServiceContract]
    public interface IHelloWorldService
    {
        [OperationContract(IsOneWay = true)]
        void Call(string ClientName);
    }
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)]
    public class HelloWorldService : IHelloWorldService
    {
        public int i;
        public void Call(string ClientName)
        {
            i++;
            Console.WriteLine("Client name :" + ClientName + " Instance:" + i.ToString() + " Thread:" + Thread.CurrentThread.ManagedThreadId.ToString() + " Time:" + DateTime.Now.ToString() + "\n\n");
            Thread.Sleep(5000);
        }
    }
}

三.运行结果分析
You can see from the output we have 6 threads serving 10 requests as compared previously we had approximately only 2 threads.
