TimeSpan.Zero Field

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

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

public static readonly TimeSpan Zero
public static final TimeSpan Zero
public static final var Zero : TimeSpan

This constant provides a convenient source for zero in time calculations.

The following code 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}" ;

            Align( TimeSpan.MaxValue ) );
        Console.WriteLine( timeFmt, "Minimum TimeSpan",

        Console.WriteLine( timeFmt, "Zero TimeSpan",

            TimeSpan.TicksPerDay );
        Console.WriteLine( numberFmt, "Ticks per hour",
