Answer by Milney for Unexpected 'is' operator result

Probably because PropertyType is a [Type] object, not a date time object...

try:

if (prop.PropertyType == typeof(System.DateTimeOffset)) {    var p = prop.Name;}

Is is for checking the type, i.e.

var maybeAStringOrMaybeAnInt = GetSomeRandomType();if (maybeAStringOrMaybeAnInt is String)
