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

The first format is recommended. It allows you to specify specific formats for other types, like displaying a hex value, or displaying some specific string format.

e.g.

string displayInHex = String.Format("{0,10:X}", value); // to display in hex

It is also more consistent. You can use the same convention to display your Debug statement. e.g.

Debug.WriteLine (String.Format("{0,10:X}", value));

Last but not least, it helps in the localisation of your program.
