C# | Add an object to the end of Collection<T> (original) (raw)

Last Updated : 01 Feb, 2019

Collection<T>.Add(T) method is used to add an object to the end of the Collection<**T**>.Syntax :

public void Add (T item);

Here, item is the object to be added to the end of the Collection<**T**>. The value can be null for reference types. Below given are some examples to understand the implementation in a better way: Example 1:

CSHARP `

// C# code to add an object to // the end of the Collection using System; using System.Collections.Generic; using System.Collections.ObjectModel;

class GFG {

// Driver code
public static void Main()
{
    // Creating a collection of strings
    Collection<string> myColl = new Collection<string>();

    myColl.Add("A");
    myColl.Add("B");
    myColl.Add("C");
    myColl.Add("D");
    myColl.Add("E");

    // Displaying the number of elements in Collection
    Console.WriteLine("The number of elements in myColl are : " 
                                               + myColl.Count);

    // Displaying the elements in Collection
    Console.WriteLine("The elements in myColl are : ");

    foreach(string str in myColl)
    {
        Console.WriteLine(str);
    }
}

}

`

Output:

The number of elements in myColl are : 5 The elements in myColl are : A B C D E

Example 2:

CSHARP `

// C# code to add an object to // the end of the Collection using System; using System.Collections.Generic; using System.Collections.ObjectModel;

class GFG {

// Driver code
public static void Main()
{
    // Creating a collection of ints
    Collection<int> myColl = new Collection<int>();

    myColl.Add(2);
    myColl.Add(3);
    myColl.Add(4);
    myColl.Add(5);

    // Displaying the number of elements in Collection
    Console.WriteLine("The number of elements in myColl are : "
                                               + myColl.Count);

    // Displaying the elements in Collection
    Console.WriteLine("The elements in myColl are : ");

    foreach(int i in myColl)
    {
        Console.WriteLine(i);
    }
}

}

`

Output:

The number of elements in myColl are : 4 The elements in myColl are : 2 3 4 5
