What is string interpolation?

interpolation is a method of concatenating, formatting, and manipulating strings. This feature was introduced in C# 6. Using string interpolation, we can use objects and expressions as a part of the string interpolation operation.

string Name= "Arun Tiwari";

string hello = $"Hello {Name} !";

Console.WriteLine(hello);

C# string interpolation allows us to insert variables into the string. It uses simple syntax and looks like a template. An interpolated string returns a string as a result.

Syntax:

$" { [,] [<:format-string>] } ..."

Example:

var s1 = $"{name} is {age} years old."; Console.WriteLine(s1);
