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

Return Value

Type: System.Int32
One of the following values.

Value

Description

-1

t1 is shorter than t2.

0

t1 is equal to t2.

1

t1 is longer than t2.

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

// TimeSpan.Equals( TimeSpan, TimeSpan ) methods.

{
    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 );

            "TimeSpan.Compare( Left, Right )", 
            TimeSpan.Compare( Left, Right ) );

            Left );

            "TimeSpan( 2, 0, 1 )" );
        CompareTimeSpans( Left, new TimeSpan( 2, 0, -1 ), 
            "TimeSpan( 2, 0, -1 )");

        CompareTimeSpans( Left, TimeSpan.FromDays( 1.0 / 12D ), 
            "TimeSpan.FromDays( 1 / 12 )" );
    }
