Remove all the strings from the StringCollection in C#

To remove all the strings from the StringCollection, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringCollection stringCol = new StringCollection();
      String[] arr = new String[] { "100", "200", "300", "400", "500" };
      Console.WriteLine("Array elements...");
      foreach (string res in arr) {
         Console.WriteLine(res);
      }
      stringCol.AddRange(arr);
      Console.WriteLine("Does the specified string is in the StringCollection? = "+stringCol.Contains("800"));
      Console.WriteLine("Total number of elements = "+stringCol.Count);
      stringCol.Clear();
      Console.WriteLine("
We have removed all the elements now..");
      Console.WriteLine("Total number of elements now = "+stringCol.Count);
   }
}

Output

This will produce the following output −

Array elements...
100
200
300
400
500
Does the specified string is in the StringCollection? = False
Total number of elements = 5

We have removed all the elements now..
Total number of elements now = 0

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringCollection stringCol = new StringCollection();
      String[] arr = new String[] { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J" };
      Console.WriteLine("Array elements...");
      foreach (string res in arr) {
         Console.WriteLine(res);
      }
      stringCol.AddRange(arr);
      Console.WriteLine("Count of elements = "+stringCol.Count);
      stringCol.Clear();
      Console.WriteLine("
Removed all the elements now...");
      Console.WriteLine("Total number of elements now = "+stringCol.Count);
   }
}

Output

This will produce the following output −

Array elements...
A
B
C
D
E
F
G
H
I
J
Count of elements = 10

Removed all the elements now...
Total number of elements now = 0
