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

Initializes a new TimeSpan to the specified number of ticks.

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

Syntax

'Declaration
Public Sub New ( _
    ticks As Long _
)

public TimeSpan(
    long ticks
)

Parameters

ticks
Type: System.Int64
A time period expressed in 100-nanosecond units.

Examples

The following code example creates several TimeSpan objects using the constructor overload that initializes a TimeSpan to a specified number of ticks.

' Example of the TimeSpan( Long ) constructor.

Module Example

   ' Create a TimeSpan object and display its value.
   Sub CreateTimeSpan(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal ticks As Long)

      Dim elapsedTime As New TimeSpan(ticks)

      ' Format the constructor for display.
      Dim ctor As String = _
          String.Format("TimeSpan( {0} )", ticks)

      ' Pad the end of a TimeSpan string with spaces if
      ' it does not contain milliseconds.
      Dim elapsedStr As String = elapsedTime.ToString()
      Dim pointIndex As Integer = elapsedStr.IndexOf(":"c)

      pointIndex = elapsedStr.IndexOf("."c, pointIndex)
      If pointIndex < 0 Then elapsedStr &= "        "

      ' Display the constructor and its value.
      outputBlock.Text &= String.Format("{0,-33}{1,24}", ctor, elapsedStr) & vbCrLf
   End Sub

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

      outputBlock.Text &= _
          "This example of the TimeSpan( Long ) constructor " & _
          vbCrLf & "generates the following output." & vbCrLf & vbCrLf
      outputBlock.Text &= String.Format("{0,-33}{1,16}", "Constructor", "Value") & vbCrLf
      outputBlock.Text &= String.Format("{0,-33}{1,16}", "-----------", "-----") & vbCrLf

      CreateTimeSpan(outputBlock, 1)
