TimeSpan.GetHashCode Method

Returns a hash code for this instance.

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

public override int GetHashCode()

Return Value

Type: System.Int32
A 32-bit signed integer hash code.

Two TimeSpan objects might have the same hash code even though they represent different time values.

The following code example generates the hash codes of several TimeSpan objects using the GetHashCode method.


// Example for the TimeSpan.GetHashCode( ) method.
using System;

class Example
{
   static void DisplayHashCode(System.Windows.Controls.TextBlock outputBlock, TimeSpan interval)
   {
      // Create a hash code and a string representation of 
      // the TimeSpan parameter.
      string timeInterval = interval.ToString();
      int hashCode = interval.GetHashCode();

      // Pad the end of the TimeSpan string with spaces if it 
      // does not contain milliseconds.
      int pIndex = timeInterval.IndexOf(':');
      pIndex = timeInterval.IndexOf('.', pIndex);
      if (pIndex < 0) timeInterval += "        ";

      outputBlock.Text += String.Format("{0,22}   0x{1:X8}, {1}",
          timeInterval, hashCode) + "\n";
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += String.Format(
          "This example of TimeSpan.Example( ) generates " +
          "the following \noutput, which displays " +
          "the hash codes of representative TimeSpan \n" +
          "objects in hexadecimal and decimal formats.\n") + "\n";
      outputBlock.Text += String.Format("{0,22}   {1,10}",
          "TimeSpan        ", "Hash Code") + "\n";
      outputBlock.Text += String.Format("{0,22}   {1,10}",
          "--------        ", "---------") + "\n";

      DisplayHashCode(outputBlock, new TimeSpan(0));
      DisplayHashCode(outputBlock, new TimeSpan(1));
      DisplayHashCode(outputBlock, new TimeSpan(0, 0, 0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(0, 1, 0));
      DisplayHashCode(outputBlock, new TimeSpan(1, 0, 0));
      DisplayHashCode(outputBlock, new TimeSpan(36000000001));
      DisplayHashCode(outputBlock, new TimeSpan(0, 1, 0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(1, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(1, 0, 0, 0));
      DisplayHashCode(outputBlock, new TimeSpan(864000000001));
      DisplayHashCode(outputBlock, new TimeSpan(1, 0, 0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(1, 0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(100, 0, 0, 0));
      DisplayHashCode(outputBlock, new TimeSpan(100, 0, 0, 0, 1));
      DisplayHashCode(outputBlock, new TimeSpan(100, 0, 0, 1));
   }
}
