Struct TimeSpan

Namespace

System

Assembly

mscorlib.dll

Represents a time interval.

public struct TimeSpan

Inherited Members

object.Equals(object, object)

object.ReferenceEquals(object, object)

object.GetType()

Remarks

A TimeSpan object represents a time interval (duration of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds, and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is unrelated to a particular date. Otherwise, the DateTime structure should be used instead. The value of a TimeSpan object is the number of ticks that equal the represented time interval. A tick is equal to 100 nanoseconds, or one ten-millionth of a second. The value of a TimeSpan object can range from MinValue to MaxValue.
