MVC2<％:标签与<％=有何不同 [英] MVC2 how is <%: tag different to <%=

问题描述

<％:和<％=吗?

what is the difference between <%: and <%= ?

推荐答案

区别在于<％:HTML自动对字符串进行编码，而<％=则不.

The difference is that <%: automatically HTML encodes the string whereas <%= does not.

返回MVC2以便对字符串进行HTML编码之前，您必须在视图内部使用Html.Encode()方法.

Back before MVC2 came out in order to HTML encode a string you had to use the Html.Encode() method inside the view.

<%= Html.Encode(Model.MyString) %>

但是，他们在MVC2中添加了<％:标记，该标记可以输出相同的内容，但可以为您处理HTML编码.

However with MVC2 they added the <%: tag, which outputs the same thing but handles the HTML encoding for you.

<%: Model.MyString %>

根据经验，除非有充分理由不这样做，否则应始终使用<％:标记 输出字符串.

As a rule of thumb you should always output your strings using the <%: tag, unless you have a good reason not to.
