MQ微軟佇列

學習通過MSMQ傳送簡單型別的訊息和複雜型別的訊息

看程式碼：

 
namespace MSMQ
{
    class Program
    {
        static void Main(string[] args)
        {
            const string path = @".\private$\myQueue";
            MyQueue.Createqueue(path);
            MyQueue.SendMessage(path, "OK1");//佇列，先進先出
            MyQueue.SendMessage(path, "Ok2");
            MyQueue.SendMessage(path, "Ok3");
            MyQueue.ReceiveMessage(path);
 
            MyQueue.SendMessage(path, new Book { BookId = 1, BookName = "Code Complete", BookPrice = 98, BookAuthor = "zzl" });
            MyQueue.SendMessage(path, new Book { BookId = 2, BookName = "Move Method", BookPrice = 47, BookAuthor = "zzl" });
 
            Console.WriteLine(MyQueue.ReceiveEntityMessage(path));
            Console.ReadKey();
        }
 
    }
