Apply string format form left to right

Question

How can you make a string that is formatted from a value from left to right?

string.Format("{0:00-00-0000}", 123);

The above returns as 00-00-0123 I would like it to be 12-30-0000

Any idea to achieve this?

Try this:

var padded = long.Parse((123).ToString().PadRight(8, '0'));
string.Format("{0:00-00-0000}", padded);
