Equality Operator

TimeSpan.Equality Operator

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Indicates whether two TimeSpan instances are equal.

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

'Declaration
Public Shared Operator = ( _
	t1 As TimeSpan, _
	t2 As TimeSpan _
) As Boolean

Parameters

t1
Type: System.TimeSpan
The first time interval to compare.
t2
Type: System.TimeSpan
The second time interval to compare.

Return Value

Type: System.Boolean
true if the values of t1 and t2 are equal; otherwise, false.

The following code example compares several TimeSpan objects to a reference TimeSpan using the Equality operator.
