TimeSpan.FromMilliseconds Method

Returns a TimeSpan that represents a specified number of milliseconds.

[Visual Basic]
Public Shared Function FromMilliseconds( _
   ByVal value As Double _
) As TimeSpan
[C#]
public static TimeSpan FromMilliseconds(
 double value
);
[C++]
public: static TimeSpan FromMilliseconds(
 double value
);
[JScript]
public static function FromMilliseconds(
   value : double
) : TimeSpan;

Parameters

value
A number of milliseconds.

Return Value

A TimeSpan that represents value.

Exceptions

Exception Type Condition
OverflowException value is less than MinValue or greater than MaxValue.
ArgumentException value is equal to Double.NaN.

Remarks

The value parameter is converted to ticks, and that number of ticks is used to intialize the new TimeSpan. Therefore, value will only be considered accurate to the nearest millisecond.

If value is Double.PositiveInfinity, MaxValue is returned. If value is Double.NegativeInfinity, MinValue is returned.

Example

[Visual Basic, C#, C++] The following code example creates several TimeSpan objects using the FromMilliseconds method.

Module FromMillisecDemo

            TimeSpan.FromMilliseconds( millisec )
        Dim timeInterval As String = interval.ToString( )

        ' Pad the end of the TimeSpan string with spaces if it 
        ' does not contain milliseconds.
        Dim pIndex As Integer = timeInterval.IndexOf( ":"c )
