使用 MVC 进行动态标记
我将标记存储在数据库中，我将其取出并放置到页面上。 下面是我所拥有的基本示例，为了便于示例，没有任何数据库调用；
控制器：
ViewData["testMarkup"] = "I was here <%= DateTime.Now.Year %>";
视图：
<%= ViewData["testMarkup"] %>
现在输出：我在这里 并且没有日期，这是因为它忽略了 <%= %>部分，我是否可以输出上述字符串并包含年份？
非常感谢，
I have markup stored in a database, which I am pulling out and placing onto a page.
below is a basic sample of what I have, without any db calls for ease of example;
The controller:
ViewData["testMarkup"] = "I was here <%= DateTime.Now.Year %>";
The View:
<%= ViewData["testMarkup"] %>
now this out puts: I was here
and no date, this is because it is ignoring the <%= %> part, is there anyway I can output the above said string and woudl include the year?
Many thanks,

只需执行以下操作：
或者我错过了什么？代码块，例如
<%= DateTime.Now.Year %>仅当它们是标记的一部分时才有效：Just do the following:
Or am I missing something? Code blocks, such as
<%= DateTime.Now.Year %>are only valid when they are part of the markup:数据库中的标记被视为字符串，而不是视图语言中的代码，因此它只是将其写为文本、C# 等。
两种替代方法：
1 - 使用模板系统，例如
并有一个方法可以在渲染时用令牌（例如
#YEAR#）的值替换令牌（例如#YEAR#），例如，Where
ReplaceTokens 看起来像：2 - 将标记存储在分部视图中，并在必要时将分部视图的名称保存在数据库中。
The markup in the database is being treated as a string, not as code in your view language, so it is simply writing it out as text, c# and all.
Two alternate methods:
1 - Use a templating system, such as
and have a method that replaces your tokens (e.g.
#YEAR#) with their values at render time, e.g.,Where
ReplaceTokenslooks like:2 - Store your markup in a partial view, and save the name of the partial view in the database if necessary.
