TimeSpan Constructor (Int64)

May 11, 2014

Initializes a new TimeSpan to the specified number of ticks.

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

public TimeSpan(
	long ticks
)

Parameters

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

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.
using System;

class Example
{
   // Create a TimeSpan object and display its value.
   static void CreateTimeSpan(System.Windows.Controls.TextBlock outputBlock, long ticks)
   {
      TimeSpan elapsedTime = new TimeSpan(ticks);

      // Format the constructor for display.
      string ctor = String.Format("TimeSpan( {0} )", ticks);

      // Pad the end of a TimeSpan string with spaces if
      // it does not contain milliseconds.
      string elapsedStr = elapsedTime.ToString();
      int pointIndex = elapsedStr.IndexOf(':');

      pointIndex = elapsedStr.IndexOf('.', pointIndex);
      if (pointIndex < 0) elapsedStr += "        ";

      // Display the constructor and its value.
      outputBlock.Text += String.Format("{0,-33}{1,24}", ctor, elapsedStr) + "\n";
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text +=
          "This example of the TimeSpan( long ) constructor " +
          "\ngenerates the following output.\n" + "\n";
      outputBlock.Text += String.Format("{0,-33}{1,16}", "Constructor", "Value") + "\n";
      outputBlock.Text += String.Format("{0,-33}{1,16}", "-----------", "-----") + "\n";

      CreateTimeSpan(outputBlock, 1);
      CreateTimeSpan(outputBlock, 999999);
      CreateTimeSpan(outputBlock, -1000000000000);
      CreateTimeSpan(outputBlock, 18012202000000);
      CreateTimeSpan(outputBlock, 999999999999999999);
      CreateTimeSpan(outputBlock, 1000000000000000000);
   }
}
