ASP.NET MVC 1.0 的数据模型验证

ASP.NET MVC 1.0 的数据模型验证
很多同学喜欢将数据的验证放在控制层(Controller)里，这是非常不对的，违背MVC的初衷，对于模型数据的验证，当然是放在模型层里才恰当。也不需要专程写一个方法在SubmitChanges之前主动去调用，实际上SubmitChanges的时候会调用OnValidate方法，该方法失败后会抛出一个Application的异常。在Controller层里捕捉这个异常再做相应的处理就行了。如此一来更省事，分工更明确，代码更优雅。

以下是一段示例代码，来自ASP.NET MVC Step by Step的例子NerdDinner(删减部分字段)。
