Int32.GetHashCode Method in C# with Examples

The Int32.GetHashCode() method in C# is used to return the hash code for the current instance.

Syntax

Following is the syntax −

public override int GetHashCode ();

Example

Let us now see an example to implement the Int32.GetHashCode() method −

using System;
public class Demo {
   public static void Main(){
      int val1 = Int32.MinValue;
      int val2 = 300;
      Console.WriteLine("Value1 = "+val1);
      Console.WriteLine("Value2 = "+val2);
      Console.WriteLine("Are they equal? = "+val1.Equals(val2));
      Console.WriteLine("HashCode for Value1 = "+val1.GetHashCode());
      Console.WriteLine("HashCode for Value2 = "+val2.GetHashCode());
   }
}

Output

This will produce the following output −

Value1 = -2147483648
Value2 = 300
Are they equal? = False
HashCode for Value1 = -2147483648
HashCode for Value2 = 300

Example

Let us now see another example to implement the Int32.GetHashCode() method −

using System;
public class Demo {
   public static void Main(){
      int val1 = 50;
      int val2 = 50;
      Console.WriteLine("Value1 = "+val1);
      Console.WriteLine("Value2 = "+val2);
      Console.WriteLine("Are they equal? = "+val1.Equals(val2));
      Console.WriteLine("HashCode for Value1 = "+val1.GetHashCode());
      Console.WriteLine("HashCode for Value2 = "+val2.GetHashCode());
   }
}

Output

This will produce the following output −

Value1 = 50
Value2 = 50
Are they equal? = True
HashCode for Value1 = 50
HashCode for Value2 = 50
