TimeSpan.Subtract Method

Subtracts the specified TimeSpan from this instance.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public TimeSpan Subtract (
	TimeSpan ts
)
public TimeSpan Subtract (
	TimeSpan ts
)
public function Subtract (
	ts : TimeSpan
) : TimeSpan
Not applicable.

Parameters

ts

A TimeSpan.

Return Value

A TimeSpan whose value is the result of the value of this instance minus the value of ts.

Exception typeCondition

OverflowException

The return value is less than MinValue or greater than MaxValue.

The return value must be between MinValue and MaxValue; otherwise, an exception is thrown.

The return value is a new TimeSpan; the original TimeSpan is not modified.

The following code example creates several pairs of TimeSpan objects and calculates their difference with the Subtract method.

// Example of the TimeSpan.Add( ) and TimeSpan.Subtract( ) methods.
using System;

class TimeSpanAddSubDemo
