How to create a StringCollection in C#

StringCollection() constructor is used to initializing a new instance of the StringCollection class. StringCollection class is a new addition to the .NET Framework class library that represents a collection of strings. StringCollection class is defined in the System.Collections.Specialized namespace.

Syntax:

public StringCollection ();

Example 1:

// C# Program to illustrate how
// to create a StringCollection
using System;
using System.Collections;
using System.Collections.Specialized;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // sc is the StringCollection object
        // StringCollection() is the constructor
        // used to initializes a new
        // instance of the StringCollection class
        StringCollection sc = new StringCollection();

        // Count property is used to get the
        // number of elements in StringCollection
        // It will give 0 as no elements
        // are present currently
        Console.WriteLine("Number of elements: "+
                                      sc.Count);
    }
}

Output:

Number of elements: 0

Example 2:

// C# Program to illustrate how
// to create a StringCollection
using System;
using System.Collections;
using System.Collections.Specialized;

class Geeks {

    // Main Method
    public static void Main(String[] args)
    {

        // sc is the StringCollection object
        // StringCollection() is the constructor
        // used to initializes a new
        // instance of the StringCollection class
        StringCollection sc = new StringCollection();

        Console.Write("Before Add Method: ");

        // Count property is used to get the
        // number of elements in StringCollection
        // It will give 0 as no elements
        // are present currently
        Console.WriteLine(sc.Count);

        Console.Write("After Add Method: ");

        // Adding elements in StringCollection
        sc.Add("A");
        sc.Add("B");
        sc.Add("C");
        sc.Add("D");
        sc.Add("E");

        // Count property is used to get the
        // number of elements in ld
        Console.WriteLine(sc.Count);
    }
}

Output:

Before Add Method: 0
After Add Method: 5
