TimeSpan.LessThan Operator

Indicates whether a specified TimeSpan is less than another specified TimeSpan.

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

public static bool operator <(
	TimeSpan t1,
	TimeSpan t2
)

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 value of t1 is less than the value of t2; otherwise, false.

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

using System;

    const string dataFmt = "{0,34}    {1}" ;

    // Compare TimeSpan parameters, and display them with the results.

This example of the TimeSpan relational operators generates
the following output. It creates several different TimeSpan
objects and compares them with a 2-hour TimeSpan.

      Right: TimeSpan( 0, 120, 0 )    02:00:00
