TimeSpan.FromTicks Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns a TimeSpan that represents a specified time, where the specification is in units of ticks.

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

Syntax

'Declaration
Public Shared Function FromTicks ( _
    value As Long _
) As TimeSpan

public static TimeSpan FromTicks(
    long value
)

Parameters

value
Type: System.Int64
A number of ticks that represent a time.

Return Value

Type: System.TimeSpan
An object that represents value.

Remarks

This is a convenience method with the same behavior as the TimeSpan.TimeSpan(Int64) constructor.

Examples

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

' Example of the TimeSpan.FromTicks( Long ) method.

Module Example

   Sub GenTimeSpanFromTicks(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal ticks As Long)

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

          "FromTicks", "TimeSpan" & vbCrLf
      outputBlock.Text &= "{0,21}{1,18}", _
          "---------", "--------" & vbCrLf
