推荐答案

IHE <一href="http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spitemeventreceiver.itemadding.aspx"相对=nofollow> ItemAdding事​​件之前>一则条记录实际添加，所以你不能使用.Item访问的字段。

Ihe ItemAdding event fires before a recored is actually added so you can't access the fields using .Item.

不过你可以从ID访问一切的除了（因为它仍然没有被创建）的<一个href="http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spitemeventproperties.afterproperties.aspx"相对=nofollow>。AfterProperties 的哈希表。

However you can access everything apart from ID (as its still not been created yet) in the .AfterProperties hash table.
