How to create a StringCollection in C#

Last Updated : 27 Feb, 2019

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
