public static bool Equals(
	DateTime t1,

)

Return Value

true if the two values are equal; otherwise, false.

			System.DateTime today2 = 
					new System.DateTime(System.DateTime.Today.Ticks);
			System.DateTime tomorrow = 
					new System.DateTime(
								System.DateTime.Today.AddDays(1).Ticks);

			// todayEqualsToday gets true. 
			bool todayEqualsToday = System.DateTime.Equals(today1, today2);

			// todayEqualsTomorrow gets false. 
			bool todayEqualsTomorrow = System.DateTime.Equals(today1, tomorrow);
