C# - Array of Class object

Array of Class object in C#

An array of class objects in C# is a collection that allows you to store multiple instances of a class. This is useful when you need to manage multiple objects of the same type.

Example

Defining a Class

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Department { get; set; }

    public Employee(int id, string name, string department)
    {
        Id = id;
        Name = name;
        Department = department;
    }
}

Declaring and Initializing an Array of Objects
1.Using Object Initializers

Employee[] employees = new Employee[]
{
    new Employee(1, "John Doe", "HR"),
    new Employee(2, "Jane Smith", "Finance"),
    new Employee(3, "Mike Brown", "IT")
};

2.Assigning Values After Declaration

Employee[] employees = new Employee[3]; // Declare an array with a size of 3

employees[0] = new Employee(1, "John Doe", "HR");
employees[1] = new Employee(2, "Jane Smith", "Finance");
employees[2] = new Employee(3, "Mike Brown", "IT");

3. Accessing Array Elements

You can access elements of the array using their index:

Console.WriteLine($"Employee Name: {employees[0].Name}, Department: {employees[0].Department}");

4. Iterating array

// foreach

foreach (var employee in employees)
{
    Console.WriteLine($"ID: {employee.Id}, Name: {employee.Name}, Department: {employee.Department}");
}


//for loop
for (int i = 0; i < employees.Length; i++)
{
    Console.WriteLine($"ID: {employees[i].Id}, Name: {employees[i].Name}, Department: {employees[i].Department}");
}
