``public static TimeSpan FromMilliseconds (double value);``
``static member FromMilliseconds : double -> TimeSpan``
``Public Shared Function FromMilliseconds (value As Double) As TimeSpan``

#### Parameters

value
Double Double Double Double

A number of milliseconds.

#### Returns

An object that represents `value`.

#### Exceptions

`value` is less than MinValue or greater than MaxValue.

-or-

`value` is PositiveInfinity.

-or-

`value` is NegativeInfinity.

`value` is equal to NaN.

## Examples

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

``````// Example of the TimeSpan::FromMilliseconds( double ) method.
using namespace System;
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 = String::Concat( timeInterval, "        " );

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

int main()
{
Console::WriteLine( "This example of TimeSpan::FromMilliseconds( double )\n"
"generates the following output.\n" );

## Remarks

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 throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);
``````
``````' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
