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
