best way to substring with variable length

Question

I want to substring a variable length string with leading spaces to 25 or less characters. i got it to work but looking for other ways?

  ...  item.LineString.Trim().Substring(0, 
item.LineString.Trim().Length > 25 ? 25 : item.LineString.Trim().Length));

Answer 1

I'd use Math.Min:

var trimmed = item.LineString.Trim();
var substring = trimmed.Substring(0, Math.Min(25, trimmed.Length));

Answer 2

You can shorten it with:

item.LineString.Trim().Substring(0, Math.Min(25, item.LineString.Trim().Length));
