Force string interpolation to always follow CultureInfo.InvariantCulture

Question

For a given .NET assembly compiled from C# (latest version), I would like to force all the string interpolations to systematically use CultureInfo.InvariantCulture instead of using CultureInfo.CurrentCulture. Is there any way to enforce this?

Answer 1

You can use the FormattableString.Invariant(FormattableString) Method.

Place a

using static System.FormattableString; 

at the top of your code and then use like

string interpolated = Invariant($"My interpolated string {3.5:N2}");

For background information look at:
