TimeSpan.CompareTo Method (Object)

Compares this instance to a specified object and returns an integer that indicates whether this instance is shorter than, equal to, or longer than the specified object.

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

public int CompareTo(
	Object value
)

Parameters

value
Type: System.Object

An object to compare, or null.

Return Value

Type: System.Int32
One of the following values.

Value

Description

-1

This instance is shorter than value.

0

This instance is equal to value.

1

This instance is longer than value.

-or-

value is null.

Implements

IComparable.CompareTo(Object)

ExceptionCondition
ArgumentException

value is not a TimeSpan.

Any instance of TimeSpan, regardless of its value, is considered greater than null.

The value parameter must be an instance of TimeSpan or null; otherwise, an exception is thrown.

The following example compares several TimeSpan structures and other objects to a reference TimeSpan structure using the CompareTo method.

// Example of the TimeSpan.CompareTo( Object ) and  
// TimeSpan.Equals( Object ) methods. 
using System;

    // Compare the TimeSpan to the Object parameters,  
    // and display the Object parameters with the results. 
    static void CompTimeSpanToObject( TimeSpan Left, object Right, 
        string RightText )
    {
        Console.WriteLine( "{0,-33}{1}", "Object: " + RightText, 
            Right );
        Console.WriteLine( "{0,-33}{1}", "Left.Equals( Object )", 
            Left.Equals( Right ) );
        Console.Write( "{0,-33}", "Left.CompareTo( Object )" );

        // Catch the exception if CompareTo( ) throws one. 
        try
        {
            Console.WriteLine( "{0}\n", Left.CompareTo( Right ) );
        }

        }
    }

    static void Main( )
    {
        TimeSpan Left = new TimeSpan( 0, 5, 0 );

        // Create objects to compare with a 5-minute TimeSpan.

            "TimeSpan( 0, 0, 300 )" );
