TimeSpan.FromMinutes Method

Returns a TimeSpan that represents a specified number of minutes, where the specification is accurate to the nearest millisecond.

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

'Declaration
Public Shared Function FromMinutes ( _
	value As Double _
) As TimeSpan

Parameters

value
Type: System.Double
A number of minutes, accurate to the nearest millisecond.

Return Value

Type: System.TimeSpan
An object that represents value.

ExceptionCondition
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 milliseconds, which 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.FromMinutes(TimeSpan.MaxValue.TotalMinutes)


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


' Example of the TimeSpan.FromMinutes( Double ) method.

Module Example

   Sub GenTimeSpanFromMinutes(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal minutes As Double)

      ' Create a TimeSpan object and TimeSpan string from 
      ' a number of minutes.
      Dim interval As TimeSpan = _
          TimeSpan.FromMinutes(minutes)
      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}", minutes, timeInterval) & vbCrLf
   End Sub

   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      outputBlock.Text &= "This example of " & _
          "TimeSpan.FromMinutes( Double )" & _
          vbCrLf & "generates the following output." & vbCrLf & vbCrLf
      outputBlock.Text &= "{0,21}{1,18}", _
          "FromMinutes", "TimeSpan" & vbCrLf
      outputBlock.Text &= "{0,21}{1,18}", _
          "-----------", "--------" & vbCrLf

      GenTimeSpanFromMinutes(outputBlock, 0.00001)
      GenTimeSpanFromMinutes(outputBlock, 0.00002)
      GenTimeSpanFromMinutes(outputBlock, 0.12345)
      GenTimeSpanFromMinutes(outputBlock, 1234.56789)

      GenTimeSpanFromMinutes(outputBlock, 1440)
