string.Format with variable names instead of numbers

Question

I've read some posts with some self implementations of this but I think now there should be some method in the ASP.NET MVC that should have this functionality.

I suppose there is some kind of method that can do what string.Format does:

 string.Format("example {0}", 1);

but instead of using {0} can work with variables names just like the MVC routes. for example:

 string.Format("example {id}", 1);

Is there such public method in ASP.NET MVC?

[Edit: Any idea how for example are action links rendered out of routes?]

Answer 1

As of C# language version 6.0 (VS2015 onwards) you can do this with Interpolated Strings (it's a compiler trick, so it doesn't matter which version of the .NET Framework you target).

The code then looks something like this

string txt = $"{person.ForeName} is not at home {person.Something}"; 

I think it makes the code more readable and less error prone, but it's not ideal if you want to put the strings into resource files for translation.
