@Html.TextBoxFor(a => a.Title, new { style = "width:80%", maxlength = "80" })
@Html.TextBoxFor(a => a.Title, new { style = "width:80%", maxlength = "80" })中a => a.Title是什么意思？
以前看了 mvc音乐商店例子好像也有，一下子忘了，找不到在什么地方
<tr>
<td width="15%">
标题：
</td>
<td colspan="3">@Html.TextBoxFor(a => a.Title, new { style = "width:80%", maxlength = "80" })
@Html.ValidationMessageFor(a => a.Title)
</td>
</tr>
