It displays the value of those properties that contain custom format strings and uses those strings to display formatted dates.

foreach (var prop in props) {
// Is this a format pattern-related property?

string fmt = prop.GetValue(dtfi, null).ToString();
Console.WriteLine("{0,-33} {1} \n{2,-37}Example: {3}\n",
