TimeSpan.Compare Method

Compares two TimeSpan values and returns an integer that indicates whether the first value is shorter than, equal to, or longer than the second value.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public static int Compare(
	TimeSpan t1,
	TimeSpan t2
)

Parameters

t1
Type: System.TimeSpan

A TimeSpan.

t2
Type: System.TimeSpan

A TimeSpan.

Return Value

Type: System.Int32

Value

Condition

-1

t1 is shorter than t2

0

t1 is equal to t2

1

t1 is longer than t2

The following code example compares several TimeSpan objects to a reference TimeSpan using the Compare method.

// Example of the TimeSpan.Compare( TimeSpan, TimeSpan ) and  
// TimeSpan.Equals( TimeSpan, TimeSpan ) methods. 
using System;

class TSCompareEqualsDemo
{
    const string dataFmt = "{0,-38}{1}" ;

    // Compare TimeSpan parameters, and display them with the results. 
    static void CompareTimeSpans( TimeSpan Left, TimeSpan Right, 
        string RightText )
    {
        Console.WriteLine( );
        Console.WriteLine( dataFmt, "Right: " + RightText, Right );
        Console.WriteLine( dataFmt, "TimeSpan.Equals( Left, Right )", 
            TimeSpan.Equals( Left, Right ) );
        Console.WriteLine( dataFmt, 
            "TimeSpan.Compare( Left, Right )", 
            TimeSpan.Compare( Left, Right ) );
    }

    static void Main( )
    {
        TimeSpan Left = new TimeSpan( 2, 0, 0 );

            "several different TimeSpan \nobjects and comparing " +
            "them with a 2-hour TimeSpan.\n" );
        Console.WriteLine( dataFmt, "Left: TimeSpan( 2, 0, 0 )", 
            Left );

        // Create objects to compare with a 2-hour TimeSpan.
        CompareTimeSpans( Left, new TimeSpan( 0, 120, 0 ), 
            "TimeSpan( 0, 120, 0 )" );
        CompareTimeSpans( Left, new TimeSpan( 2, 0, 1 ), 
            "TimeSpan( 2, 0, 1 )" );
        CompareTimeSpans( Left, new TimeSpan( 2, 0, -1 ), 
            "TimeSpan( 2, 0, -1 )");
        CompareTimeSpans( Left, new TimeSpan( 72000000000 ), 
            "TimeSpan( 72000000000 )" );
        CompareTimeSpans( Left, TimeSpan.FromDays( 1.0 / 12D ), 
            "TimeSpan.FromDays( 1 / 12 )" );
    }
