Array, ArrayList, List and Dictionary in ASP.Net

Array, ArrayList, List and Dictionary all represent a collection of data but each are designed to satisfy differnt requirements. This article attempts to explain them with very basic examples; once you go this article I hope the next time you will feel a little more comfortable deciding what to choose and why.

Array
dataType[] myArray = new dataType[size];

Fixed number of array size
Strictly type-safe
Collection of elements of the same data type only
Elements are accessed by zero-based index
Array class is in the System Namespace (in other words, it is automatically available)
Values are assigned by assignment operator as in the following:
int[] intArray = new int[5];
intArray[0] = 2;
intArray[1] = 4;
intArray[2] = 6;

intArray[3] = 8;

intArray[4] = 10;
intArray[5] = 12; //Run time errorintArray[6] = "Hello";//Compile time errorforeach (int i in intArray)
{

Console.WriteLine("From array " + i);

}
Console.WriteLine("From array " + intArray[6]); //Run time error

ArrayList
ArrayList myArrayList = new ArrayList();

Size varies as required
Not type-safe
Collection of elements of the same or various data types
Reverse, Contains, Sort and a few other usefull methods are available that we don't get with Arrays
Useful when you are not sure about the size of the collection or you may need to have more than one data type in the collection
Elements are accessed by zero-based index
The data type of an ArrayList is an object type
Dictionary classes are in the System.Collections Namespace
Values are assigned by calling the Add method as in the following:

ArrayList myArrayList = new ArrayList();

myArrayList.Add(2);

myArrayList.Add("OOPS");

foreach (object obj in myArrayList)

{

Console.WriteLine("From arrayList " + obj.ToString());

}

Console.WriteLine("-------");

List
List<T> myList = new List<T>(); // T for data type

Size varies as required
Strictly type-safe
Collection of elements of the same data type only
Reverse, Contains, Sort and a few other useful methods are available that we don't get with Arrays
Useful if you want to have the features of both Array and ArrayList
Elements are accessed by zero-based index
Dictionary classes are in the System.Collections.Generic Namespace
Values are assigned by calling the Add method as in the following:

List<int> intList = new List<int>();

intList.Add(2);

intList.Add(8);

intList.Add(4);

intList.Add(6);

foreach (int i in intList)

{

Console.WriteLine("From List " + i);

}

Dictionary
Dictionary<keyDataType, valueDataType> myCollection = new Dictionary<keyDataType, valueDataType>();

Size can vary
Can't have mixed data types, type-safe
The Collection is defined as a key-value pair
All of the keys must be of the same data type
All of the values must be of the same data type
Useful to deal with custom data type
Elements are accessed based on key
Dictionary classes are in the System.Collections.Generic Namespace
Key-Values are assigned by calling the Add method as in the following:

Dictionary<string,Employee> Employees =new Dictionary<string,Employee>();

Employee emp1 = new Employee("Emp01","Employee1");

Employee emp2 = new Employee("Emp02","Employee2");

Employee emp3 = new Employee("Emp03","Employee3");

Employee emp4 = new Employee("Emp04","Employee4");

Employee emp5 = new Employee("Emp05","Employee5");

Employees.Add(emp1.empID, emp1);

Employees.Add(emp2.empID, emp2);

Employees.Add(emp3.empID, emp3);

Employees.Add(emp4.empID, emp4);

Employees.Add(emp5.empID, emp5);

Console.WriteLine(Employees["Emp05"].getNameAndID());

foreach (KeyValuePair<string,Employee> emp in Employees)

{

   Console.WriteLine(emp.Key +" >>>>> " + emp.Value.empName);

   Console.WriteLine(emp.Value.ToString());

}

    public class Employee

    {

        public string empID;

        public readonly string empName;

        public Employee(string empID, string name)

        {

            this.empID = empID;

            this.empName = name;

        }

    }
