Is it possible to pass interpolated strings as parameter to a method?

Question

I have started to use Interpolated Strings (new feature of C# 6) and it is really useful and gracefully. But according to my needs I have to pass format of string to a metho

Answer 1

There are several ways you can do this.

The first one is to add another method overload that takes a FormattableString (a new typed used by one of the variants of string interpollation) and calls the original one:

public void MyMethod(FormattableString fs)
{
    MyMethod(fs.Format);
}

And you also have access to the arguments if you need to.

If you only need the format, just create an extension method to extract it:

public static string AsFormat(FormattableString fs)
{
    return fs.Format;
}
