c# string formatting

Question

I m curious why would i use string formatting while i can use concatenation such as

Console.WriteLine(\"Hello {0} !\", name);

Console.WriteLine(\"Hello \"+          


        

Answer 1

String formatting allows you to keep the format string separate, and use it where it's needed properly without having to worry about concatenation.

string greeting = "Hello {0}!";
Console.WriteLine(greeting, name);

As for why you would use it in the exact example you gave... force of habit, really.
