C# | Remove all the strings from the StringCollection

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.Clear method is used to remove all the strings from the StringCollection.

Syntax:

public void Clear ();

Note:

• Count is set to zero, and references to other objects from elements of the collection are also released.
• This method is an O(n) operation, where n is Count.

Example:

// C# code to insert a string into
// the StringCollection at the
// specified index
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[] {"Hello", "Geeks",
                                "for", "GeeksforGeeks"};

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

        Console.WriteLine("Initially elements in StringCollection are: ");

        // Displaying elements in StringCollection
        // named myCol
        foreach(Object obj in myCol)
            Console.WriteLine(obj);

        // Removing all the elements from StringCollection
        myCol.Clear();

        Console.WriteLine("After Removing: ");

        // Displaying elements in StringCollection
        // named myCol
        foreach(Object obj in myCol)
            Console.WriteLine(obj);
    }
}

Output:

Initially elements in StringCollection are: 
Hello
Geeks
for
GeeksforGeeks
After Removing:
