	double value
)
public DateTime AddMilliseconds (
	double value

public function AddMilliseconds (
	value : double
) : DateTime

Parameters

value

A number of whole and fractional milliseconds. The value parameter can be negative or positive. Note that this value is rounded to the nearest integer.

Return Value

A DateTime whose value is the sum of the date and time represented by this instance and the number of milliseconds represented by value.

Exception typeCondition

ArgumentOutOfRangeException

The resulting DateTime is less than MinValue or greater than MaxValue.

This method does not change the value of this DateTime. Instead, a new DateTime is returned whose value is the result of this operation.

The fractional part of value is the fractional part of a millisecond. For example, 4.5 is equivalent to 4 milliseconds, and 5000 ticks, where one millisecond = 10000 ticks.

The value parameter is rounded to the nearest integer.
