Is it possible to create an extension method to format a string?

Question

the question is really simple. How do we format strings in C#? this way:

 string.Format(\"string goes here with placeholders like {0} {1}\", firstName, lastN         


        

Answer 1

Yes it is possible:

public static class StringFormatExtensions {
  public static string Format(this string formatStr, params object[] args) {
    return string.Format(formatStr, args);
  }
}

It would be good to add overloads for cases of one and two arguments.

Overall however, I don't see much value to this.
