Get the hash code for this instance in C#
To get the hash code for this instance, the code is as follows −
Example
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 −
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
