Get the hash code for this instance in C#

To get the hash code for this instance, the code is as follows −

Example

 Live Demo

using System; public class Demo {    public static void Main() {       string[] arr = {"tom", "amit", "kevin", "katie"};       Type t1 = arr.GetType();       Type t2 = t1.GetElementType();       Console.WriteLine("Type = "+t2.ToString());       Console.WriteLine("Hash Code = "+t1.GetHashCode());    } }

Output

This will produce the following output −

Type = System.String Hash Code = 9144789

Example

Let us see another example −

 Live Demo

using System; public class Demo {    enum Vehicle {Car, Bus, Bike, Airplane}    public static void Main() {       try {          Vehicle v = Vehicle.Bike;          Type type = v.GetType();          Console.WriteLine("Hash code = "+type.GetHashCode());          string[] str = type.GetEnumNames();          Console.WriteLine("GetEnumName() to return the constant name = " + str);          Type type2 = type.GetEnumUnderlyingType();          Console.Write("Enum Underlying type = "+type2);          Array arrObj = type.GetEnumValues();          Console.Write("Values = "+arrObj);          Console.WriteLine("
Listing constants ..");          for (int i = 0; i < str.Length; i++)             Console.Write("{0} ", str[i]);       }       catch (ArgumentException e) {          Console.WriteLine("Not an enum!");          Console.Write("{0}", e.GetType(), e.Message);       }    } }

Output

This will produce the following output −

Hash code = 44757566 GetEnumName() to return the constant name = System.String[] Enum Underlying type = System.Int32Values = Demo+Vehicle[] Listing constants .. Car Bus Bike Airplane
