通过使用过程生成的变量标识符返回值

Question

An example:

@foreach (var p in products)
{
    <a href="/@(p.Path)">@translations.@(p.TextId)</a>
}

The @translations.@(p.textId) does not work, but that is along the lines what I think of as the procedurally generated variable identifier .

I imagine, to return value that would correspond to, as if I'd have written: @translations.helloworldproduct or @translations.otherproduct .

And in my translations database, I'd have: helloworldproduct = "Hello, World!" and otherproduct = "Yet another product test." .

The HTML result would be:

<a href="/products/1">Hello, World!</a>
<a href="/products/2">Yet another product test.</a>

Is anything like this possible?

Answer 1

That won't work because you're essentially trying to pull the equivalent of a JS eval . Well ok, you can get it to work, but you'd have to use reflection and it's both ugly and slow.

You'd be much better off giving translations an indexer, such as the one provided for free with the generic Dictionary<TKey, TValue> . (Note I'm not sure what type translations is. I'm assuming it's either an anonymous type or some concrete class with properties.) Then you could use the indexer:

@translations[p.TextId]
