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
