C# BlockingCollection(生产者/消费者)练习
最近接手同事C#代码,(话说我一个C++程序员干嘛做这种事情,可能我是韭菜吧),为了能够承接,特地去拜读了《C#图解教程》,入门还是不错的。
写代码嘛,异步编程肯定少不了,下面就是利用C# BlockingCollection功能模块编写的 生产者/消费者 demo(韭菜要自觉生产,提供给多人消费)。
using System;
using System.Threading;
using System.Threading.Tasks;
using System.Collections.Concurrent;
namespace ConsoleApp2
{
class Collection
{
public static BlockingCollection<int> bc = new BlockingCollection<int>();
}
class Producer
{
public static async Task Producer_fun()
{
await Task.Run(() => {
for (int i = 0; i < 100; i++)
{
Thread.Sleep(50);
Collection.bc.Add(i);
Console.WriteLine($"韭菜生产 {i}");
}
Collection.bc.CompleteAdding();
});
}
}
class Consumer
{
public static int n = 0;
public static async Task Consumer_fun(string str)
{
await Task.Run(() =>
{
while(true){
Thread.Sleep(200);
if (Collection.bc.TryTake(out n))
{
Console.WriteLine($"{str}掠夺 {n}");
}
else
{
if (Collection.bc.IsCompleted)
break;
}
}
});
}
}
class Program
{
static void Main(string[] args)
{
Task t1 = Producer.Producer_fun();
Task t2 = Consumer.Consumer_fun("JD");
Task t3 = Consumer.Consumer_fun("ali");
Task t4 = Consumer.Consumer_fun("QQ");
Task t5 = Consumer.Consumer_fun("apple");
Task.WaitAll(t1, t2, t3,t4,t5);
}
}
}
相对于C++来说,C#的BlockingCollection(生产/消费)使用真的非常方便,还线程安全。。。。
