ASP.NET MVC3 快速入门-第七节在Movie(电影)模型与数据表中添加一个字段

在本节中我们将要对我们的模型类进行修改，同时介绍如何在ASP.NET MVC3中根据这些修改来调整我们数据表的结构。
<h2 style="text-indent: 0cm; margin: 0cm 0cm 0pt; mso-list: none; tab-stops: 21.0pt;">7.1 在我们的Movie模型中添加一个Rating(电影等级)属性</h2>
 首先，我们在现存的Movie类中添加一个附加的“Rating”属性。打开Movie.cs文件，在Movie类中添加一个Rating属性，如下所示。
<div style="padding-bottom: 4pt; padding-left: 4pt; padding-right: 31pt; background: #f0f7fe; margin-left: 0cm; margin-right: 28.65pt; padding-top: 4pt; mso-element: para-border-div; mso-border-alt: solid #CCCCCC .75pt; border: #cccccc 1pt solid;">
<p style="text-indent: 17pt; margin: 0cm 0cm 0pt; background: #f0f7fe; mso-border-alt: solid #CCCCCC .75pt; mso-char-indent-count: 2.0; mso-margin-bottom-alt: auto; mso-para-margin-right: 2.73gd; mso-line-height-alt: 0pt; mso-padding-alt: 4.0pt 31.0pt 4.0pt 4.0pt; padding: 0cm;">public string Rating { get; set; }
</div>
 现在完整的Movie类的代码如代码清单7-1所示。
