Asp.Net - 可以输入 LinkButton.CommandArgument 吗？

好的，给定一个像这样声明的 Repeater 的 ItemTemplate 内的 LinkButton -

<asp:LinkButton ID="restrictionDelete" runat="server" CssClass="restrictionDelete" Text="Delete..."
                OnCommand="lnkDeleteRestriction_Command" CommandName="Delete" CommandArgument="<%# Container.DataItem %>"></asp:LinkButton>

现在，..repeater 被绑定到一个列表Restriction 对象，因此当 lnkDeleteRestriction_Command 被触发时，我希望可以强制转换 CommandEventArgs.CommandArgument 这是一个对象到我的 Restriction 类型。似乎并非如此，..我只是将完全限定的类型名称作为字符串获取。

我可以接收类型化的命令参数吗？如果不能，为什么它是一个对象？

提前致谢，

Okay so given a LinkButton inside a the ItemTemplate of a Repeater declared like this -

<asp:LinkButton ID="restrictionDelete" runat="server" CssClass="restrictionDelete" Text="Delete..."
                OnCommand="lnkDeleteRestriction_Command" CommandName="Delete" CommandArgument="<%# Container.DataItem %>"></asp:LinkButton>

Now,..the repeater is being bound to a list of Restriction objects so when the lnkDeleteRestriction_Command is fired I'm expecting that I can cast the CommandEventArgs.CommandArgument which is an object to my Restriction type. This doesn't seem to be so,..I just get the fully qualified type name as a string.

Can I receive a typed command argument at all and if not, why is it an object?

Thanks in advance,
