This is used in Console.WriteLine and also string.format hence its inclusion here.
Layout of the PlaceHolder
The three parts areindex, alignment : formatSo {0:X} (x means Hexadecimal) or {0,10} meaning output in a width of 10. The alignment value specifies teh width and left or right alignment by using - (left aligned) or + (right aligned) numbers. 10 Means right aligned in a width of 10, -6 means left aligned in a width of 6. Alignment is ignored if the output exceeds the width.
This provides a large number of formatting examples.

- s - sortable . yyyy-MM-ddTHH:mm:ss

This concludes this tutorial. The next C# programming tutorial will be on Windows forms.
