TimeSpan.FromMilliseconds Method

Returns a TimeSpan that represents a specified number of milliseconds.

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

public static TimeSpan FromMilliseconds (
	double value
)
public static TimeSpan FromMilliseconds (
	double value
)
public static function FromMilliseconds (
	value : double
) : TimeSpan
Not applicable.

Parameters

value

A number of milliseconds.

Return Value

A TimeSpan that represents value.

Exception typeCondition

OverflowException

value is less than MinValue or greater than MaxValue.

-or-

value is Double.PositiveInfinity.

-or-

value is Double.NegativeInfinity.

ArgumentException

value is equal to Double.NaN.

The value parameter is converted to ticks, and that number of ticks is used to initialize the new TimeSpan. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this conversion can generate an OverflowException for values that are near to but still in the range of either MinValue or MaxValue. For example, this causes an OverflowException in the following attempt to instantiate a TimeSpan object.

The following code example creates several TimeSpan objects using the FromMilliseconds method.

// Example of the TimeSpan.FromMilliseconds( double ) method.
using System;

class FromMillisecDemo
{
    static void GenTimeSpanFromMillisec( Double millisec )
    {
        // Create a TimeSpan object and TimeSpan string from 
        // a number of milliseconds.
        TimeSpan    interval = TimeSpan.FromMilliseconds( millisec );
        string      timeInterval = interval.ToString( );

        // Pad the end of the TimeSpan string with spaces if it 
        // does not contain milliseconds.
        int pIndex = timeInterval.IndexOf( ':' );
        pIndex = timeInterval.IndexOf( '.', pIndex );
        if( pIndex < 0 )   timeInterval += "        ";

        Console.WriteLine( "{0,21}{1,26}", millisec, timeInterval );
    }

            "This example of TimeSpan.FromMilliseconds( " +
            "double )\ngenerates the following output.\n" );
        Console.WriteLine( "{0,21}{1,18}", 
            "FromMilliseconds", "TimeSpan" );
        Console.WriteLine( "{0,21}{1,18}", 
            "----------------", "--------" );

        GenTimeSpanFromMillisec( 1 );
        GenTimeSpanFromMillisec( 1.5 );
