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
