TimeSpan.FromMilliseconds Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Returns a TimeSpan that represents a specified number of milliseconds.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Function FromMilliseconds ( _
value As Double _
) As TimeSpan
public static TimeSpan FromMilliseconds(
double value
)
Parameters
- value
Type: System.Double
A number of milliseconds.
Return Value
Type: System.TimeSpan
An object that represents value.
Exceptions
| Exception | Condition |
|---|---|
| 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. |
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
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);
Examples
The following code example creates several TimeSpan objects using the FromMilliseconds method.

Module Example
Sub GenTimeSpanFromMillisec(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal millisec As Double)
' Create a TimeSpan object and TimeSpan string from
' a number of milliseconds.
Dim interval As TimeSpan = _
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)
pIndex = timeInterval.IndexOf("."c, pIndex)
If pIndex < 0 Then timeInterval &= " "
outputBlock.Text &= String.Format("{0,21}{1,26}", millisec, timeInterval) & vbCrLf
