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

public TimeSpan Duration()

Return Value

Type: System.TimeSpan
A new object whose value is the absolute value of the current TimeSpan object.

ExceptionCondition
OverflowException

The value of this instance is TimeSpan.MinValue.

The following example applies the Duration method to several TimeSpan objects.

// Example of the TimeSpan.Duration( ) and TimeSpan.Negate( ) methods, 
// and the TimeSpan Unary Negation and Unary Plus operators. 
using System;

class DuraNegaUnaryDemo
{
    const string dataFmt = "{0,22}{1,22}{2,22}" ;

    static void ShowDurationNegate( TimeSpan interval )
    {
        // Display the TimeSpan value and the results of the  
        // Duration and Negate methods.
        Console.WriteLine( dataFmt, 
            interval, interval.Duration( ), interval.Negate( ) );
    }

    static void Main()
    {
        Console.WriteLine(
            "This example of TimeSpan.Duration( ), " +
            "TimeSpan.Negate( ), \nand the TimeSpan Unary " +
            "Negation and Unary Plus operators \n" +
            "generates the following output.\n" );
        Console.WriteLine( dataFmt, 
            "TimeSpan", "Duration( )", "Negate( )" );
        Console.WriteLine( dataFmt, 
            "--------", "-----------", "---------" );

        // Create TimeSpan objects and apply the Unary Negation 
        // and Unary Plus operators to them.
        ShowDurationNegate( new TimeSpan( 1 ) );
        ShowDurationNegate( new TimeSpan( -1234567 ) );
        ShowDurationNegate( 
            + new TimeSpan( 0, 0, 10, -20, -30 ) );
        ShowDurationNegate( 
            + new TimeSpan( 0, -10, 20, -30, 40 ) );
        ShowDurationNegate( 
            - new TimeSpan( 1, 10, 20, 40, 160 ) );
        ShowDurationNegate( 
            - new TimeSpan( -10, -20, -30, -40, -50 ) );
    }
