TimeSpan.Zero Field

Definition

Represents the zero TimeSpan value. This field is read-only.

public static readonly TimeSpan Zero;

Field Value

Examples

The following example references and displays the value of the Zero field.

// Example of the TimeSpan fields.
using System;

class TimeSpanFieldsDemo
{
    // Pad the end of a TimeSpan string with spaces if it does not 
    // contain milliseconds.
    static string Align( TimeSpan interval )
    {
        string  intervalStr = interval.ToString( );
        int     pointIndex = intervalStr.IndexOf( ':' );

        pointIndex = intervalStr.IndexOf( '.', pointIndex );
        if( pointIndex < 0 ) intervalStr += "        ";
        return intervalStr;
    } 

    static void Main( )
    {
        const string numberFmt = "{0,-22}{1,18:N0}" ;
        const string timeFmt = "{0,-22}{1,26}" ;

        Console.WriteLine( numberFmt, "-----", "-----" );

        // Display the maximum, minimum, and zero TimeSpan values.
        Console.WriteLine( timeFmt, "Maximum TimeSpan", 
            Align( TimeSpan.MaxValue ) );
        Console.WriteLine( timeFmt, "Minimum TimeSpan", 
            Align( TimeSpan.MinValue ) );
        Console.WriteLine( timeFmt, "Zero TimeSpan", 
            Align( TimeSpan.Zero ) );
        Console.WriteLine( );

        // Display the ticks-per-time-unit fields.
        Console.WriteLine( numberFmt, "Ticks per day", 
            TimeSpan.TicksPerDay );
        Console.WriteLine( numberFmt, "Ticks per hour", 
            TimeSpan.TicksPerHour );
        Console.WriteLine( numberFmt, "Ticks per minute", 
            TimeSpan.TicksPerMinute );
        Console.WriteLine( numberFmt, "Ticks per second", 
            TimeSpan.TicksPerSecond );
        Console.WriteLine( numberFmt, "Ticks per millisecond", 
            TimeSpan.TicksPerMillisecond );
    }

Remarks

Because the value of the Zero field is a TimeSpan object that represents a zero time value, you can compare it with other TimeSpan objects to determine whether the latter represent positive, non-zero, or negative time intervals. You can also use this field to initialize a TimeSpan object to a zero time value.
