介绍
工作队列主要用于异步处理消息,详细介绍参考其他文章,这里主要提供使用方法
类似方法有List、HashMap、Dir,但是性能略逊一筹。
场景举例
硅晶片标刻:
通讯协议采用TCP协议
1、程序(Server)对接上游LAMA机器(Client),接受标刻条码信息。
2、程序(Client)控制激光打标机(Server),在硅晶片上标刻条码
3、程序(Client)读取扫码器(Server)读码信息,并于标刻条码信息对比
简单调用举例
struct recivecode
{
public string ID;
public string STATION;
}
WorkQueue<recivecode> l_queue = new WorkQueue<recivecode>();
WorkQueue<long> l_markcode = new WorkQueue<long>();
recivecode REC = new recivecode();
REC.ID = IDimforation;
REC.STATION = station;
l_queue.EnqueueBox(REC);
recivecode code = l_queue.TryDequeueBox();
Console.WriteLine(code.ID);
