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?

You can specify if string interpolation should use the invariant culture by using learn.microsoft.com/en-us/dotnet/api/… – Tommie

#2329797 – Ovolo

See #32077323 – Danonorwegian

This question is similar to: String Interpolation in Visual Studio 2015 and IFormatProvider (CA1305). If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. – Danonorwegian

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:

• Interpolated strings: advanced usages.
• String interpolation using $ / Implicit conversions and how to specify IFormatProvider implementation.
