How to declare an array of Custom Type in C#

Introduction

In this article we will see that how we can create arrays of custom types. We can achieve it by using custom types.We all know that array is a reference type i.e. memory for an array is allocated in a heap.Sometimes we need to declare arrays of custom types rather than arrays of predefined types ( int or string etc).

Following are the steps to declare an array of custom type,

Step 1 :

Start a new console application project

Step2:

Create a class Employee as shown below

class Employee
    {public string empName { set; get; }public string empAddress { set; get; }
    }

 Step3:

Declare the array of two employees in the same way as we are declaring it for predefined datatype.

Employee[] newEmployee = new Employee[2];

Here new employee is the array of Employee. Here we have given the size of this array as 2 so it will create two reference types. Each will point to Employee class.

Complete Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace UsingRefTypeInArray
{class Program
    {static void Main(string[] args)
        {
            Employee[] newEmployee = new Employee[2];
            newEmployee[0] = new Employee { empName = "Ravish", empAddress = "Haryana" };
            newEmployee[1] = new Employee { empName = "Nihar", empAddress = "Udisa" };
            Console.WriteLine("Employee Details");foreach (var v in newEmployee)
            {
                Console.WriteLine("NAme:" + v.empName + " Address: "+  v.empAddress +"\nNext\n");
            }
            Console.Read();
        }
    }class Employee
    {public string empName { set; get; }public string empAddress { set; get; }
    }
}

 When we execute it than we will get the output in the below format: 

In this way we can create an array of custom types and retrieve the value from it.that's all enjoy.
