这将构建路径行动，返回一个URL，执行操作的不结果。

It will construct the path to the action, returning a url, not the results of executing the action.

结果将是：

<td>
   <img src='/User.mvc/DisplayImage?id=U00915441' alt="" />
</td>

举例code。假设你的用户模型存储在一个字节数组中的形象。如果您在使用LINQ和属性是二进制，然后用（）将其转换为一个字节数组方法。请注意，这将要求用户在使用GET请求记录的属性。

Example code. assumes your user model has the image stored in a byte array. If you are using LINQ and the property is a Binary, then use the ToArray() method to convert it to a byte array. Note the attributes which will require that the user be logged in and using a GET request.
