我在我的程序中實現了一個消息傳遞系統。它的功能就像電子郵件，只是它完全包含在系統中。有誰知道ASP.Net電子郵件控件/用戶控件？
我想知道是否有人看到我可以修改的電子郵件控件模板。它會有一個收件箱，消息查看和消息發送部件。
我只是重新發送郵件&接收部分到我的鉤到我的表。
謝謝！

好吧，我沒有意識到我寫了這麼多。如果你使用這個，請確保你信任Biff_MaGriff。 ：D 技術是.net 3.5與SubSonic 3.0
其餘在我的答案。
最終應該看起來像這樣。 （減去所有我的切口）

所以你不會到電子郵件？.. – 2010-08-17 13:55:07
不，用戶之間只是系統間的通訊。全部存儲在數據庫中。 – 2010-08-17 14:21:14
是的，這是一個很好的面板欄，但是我更多地考慮一個擁有該功能的控件，快速查看所有消息和單個消息的視圖。哦，也許我必須脫掉我的屁股並自己寫下這件事。 – 2010-08-18 19:34:54
