.Net使用消息隊列，借助windows組件來存儲要完成的一系列任務，不用程序使用同一個隊列，方便不同程序之間的數(shù)據(jù)共享和協(xié)作……
以本人經(jīng)驗，這個在某個方面類似于session（當然還有很多方面不同）,相同之處：session可以把信息存儲在aspnet_state服務中，網(wǎng)站重新編譯或者重新啟動網(wǎng)站，session不會丟失（session超時是正常情況，這種情況除外）。
win7中安裝消息隊列組件，其他操作系統(tǒng)請百度搜索相關資料。
如果服務沒有自動啟動，需要啟動服務：
先創(chuàng)建隊列，再使用隊列，隊列中的消息，發(fā)送一個多一個，接收一個少一個，先進先出。
