C# 并发安全集合ConcurrentBag取代List

List集合是非线程安全的，所以我们这里了解下安全集合ConcurrentBag。

控制台测试程序：

using System;
using System.Collections.Concurrent;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace MyConcurrent
{
    class Program
    {
        /// 

        /// ConcurrentBag并发安全集合
        /// 
        public static void ConcurrentBagWithPallel()
        {
            ConcurrentBag list = new ConcurrentBag();
            Parallel.For(0, 10000, item =>
            {
                list.Add(item);
            });
            Console.WriteLine("ConcurrentBag's count is {0}", list.Count());
            int n = 0;
            foreach (int i in list)
            {
                if (n > 10)
                    break;
                n++;
                Console.WriteLine("Item[{0}] = {1}", n, i);
            }
            Console.WriteLine("ConcurrentBag's max item is {0}", list.Max());
        }
        
 
        /// 

        /// 函数入口
        /// 
        /// 
        static void Main(string[] args)
        {
            Console.WriteLine("ConcurrentBagWithPallel is runing" );
            ConcurrentBagWithPallel();
 
            Console.Read();
        }
