Parameters

value

A boxed object to compare, or null.

Returns

A signed number indicating the relative values of this instance and value.

Less than zero	This instance is earlier than value.
Zero	This instance is the same as value.
Greater than zero	This instance is later than value, or value is null.

Exceptions

Type	Reason
ArgumentException	value is not a DateTime and is not a null reference.

Remarks

Before comparing DateTime objects, make sure that the objects represent times in the same time zone. You can do this by comparing the values of their DateTime.Kind properties.

Any instance of DateTime, regardless of its value, is considered greater than null.
