有谁知道ASP.Net电子邮件控件/用户控件？

我在我的程序中实现了一个消息传递系统。它的功能就像电子邮件，只是它完全包含在系统中。有谁知道ASP.Net电子邮件控件/用户控件？

我想知道是否有人看到我可以修改的电子邮件控件模板。它会有一个收件箱，消息查看和消息发送部件。

我只是重新发送邮件&接收部分到我的钩到我的表。

谢谢！

好吧，我没有意识到我写了这么多。如果你使用这个，请确保你信任Biff_MaGriff。：D 技术是.net 3.5与SubSonic 3.0

其余在我的答案。

最终应该看起来像这样。（减去所有我的切口）

所以你不会到电子邮件？.. – 2010-08-17 13:55:07

不，用户之间只是系统间的通讯。全部存储在数据库中。 – 2010-08-17 14:21:14

是的，这是一个很好的面板栏，但是我更多地考虑一个拥有该功能的控件，快速查看所有消息和单个消息的视图。哦，也许我必须脱掉我的屁股并自己写下这件事。 – 2010-08-18 19:34:54

我最终创建了自己的用户控件。如果任何人有兴趣的消息，我会发布的细节。

如果你愿意到餐桌出一些钱，Telerik有一个不错的PanelBar控制，看起来就像Outlook一样。我相信随附的样本与其网站上类似Outlook的演示应用程序完全相同，因此这可能是一种非常快速简单的入门方法。

仅供参考，面板栏控件只是一个UI，它不提供消息功能。当然，你可以用它来使你的消息系统看起来像outlook，但你仍然需要自己编码。
