Code inspection: Redundant string interpolation

This inspection reports interpolated strings that do not have any interpolation expressions inside. In this case, the interpolated strings — for example $"text" — can be replaced with a regular string literal "text".

Although the redundant $ character will not influence your code in any way, this inspection can still help you spot places that look like interpolated expressions but are not:

        
public class Sample
{
    void Print(string name)
    {
        // No interpolation expressions
        Console.WriteLine($"Hello (name)");

        // Interpolation expressions in the sting
        Console.WriteLine($"Hello {name}");
    }
}
