C# | Get the number of strings in StringCollection

Last Updated : 01 Feb, 2019

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. StringCollection.Count property is used to get the number of strings contained in the StringCollection. Syntax:

public int Count { get; }

Return Value: It returns the number of strings contained in the StringCollection. Note: Retrieving the value of this property is an O(1) operation. Below programs illustrate the use of StringCollection.Count Property: Example 1:

CSHARP

// C# code to get the number of strings
// contained in the StringCollection
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // creating a StringCollection named myCol
        StringCollection myCol = new StringCollection();

        // creating a string array named myArr
        String[] myArr = new String[] { "First", "Second", "Third",
                                        "Fourth", "Fifth" };

        // Copying the elements of a string
        // array to the end of the StringCollection.
        myCol.AddRange(myArr);

        // To get number of Strings contained
        // in the StringCollection
        Console.WriteLine("Number of strings in myCol are : " + myCol.Count);
    }
}

Output:

Number of strings in myCol are : 5

Example 2:

CSHARP

// C# code to get the number of strings 
// contained in the StringCollection
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // creating a StringCollection named myCol
        StringCollection myCol = new StringCollection();

        // creating a string array named myArr
        String[] myArr = new String[] {};

        // Copying the elements of a string
        // array to the end of the StringCollection.
        myCol.AddRange(myArr);

        // To get number of Strings contained
        // in the StringCollection
        Console.WriteLine("Number of strings in myCol are : " 
                                              + myCol.Count);
    }
}
