Int64.GetHashCode Method in C# with Examples

The Int64.GetHashCode() method in C# is used to return the hash code for this instance.

Syntax

Following is the syntax −

public override int GetHashCode ();

Example

Let us now see an example to implement the Int64.GetHashCode() method −

using System;
public class Demo {
   public static void Main(){
      long val1 = 8768768768;
      long val2 = 7889765555;
      Console.WriteLine("Value1 = "+val1);
      Console.WriteLine("Value2 = "+val2);
      Console.WriteLine("Are they equal? = "+val1.Equals(val2));
      Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode());
      Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
   }
}

Output

This will produce the following output −

Value1 = 8768768768
Value2 = 7889765555
Are they equal? = False
Value1 (HashCode) = 178834178
Value2 (HashCode) = -700169038

Example

Let us now see another example to implement the Int64.GetHashCode() method −

using System;
public class Demo {
   public static void Main(){
      long val1 = 0;
      long val2 = Int64.MaxValue;
      Console.WriteLine("Value1 = "+val1);
      Console.WriteLine("Value2 = "+val2);
      Console.WriteLine("Are they equal? = "+val1.Equals(val2));
      Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode());
      Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
   }
}

Output

This will produce the following output −

Value1 = 0
Value2 = 9223372036854775807
Are they equal? = False
Value1 (HashCode) = 0
Value2 (HashCode) = -2147483648
