TimeSpan.LessThanOrEqual Operator

Indicates whether a specified TimeSpan is less than or equal to another specified TimeSpan.

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

'Declaration
Public Shared Operator <= ( _
	t1 As TimeSpan, _
	t2 As TimeSpan _
) As Boolean
'Usage
Dim t1 As TimeSpan 
Dim t2 As TimeSpan 
Dim returnValue As Boolean 

returnValue = (t1 <= t2)

Parameters

t1
Type: System.TimeSpan

A TimeSpan.

t2
Type: System.TimeSpan

A TimeSpan.

Return Value

Type: System.Boolean
true if the value of t1 is less than or equal to the value of t2; otherwise, false.

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