How to create a StringCollection in C#?

To create a StringCollection in C#, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      StringCollection strCol = new StringCollection();
      String[] strArr = new String[] { "A", "B", "C", "D", "E", "F", "G", "H" };
      Console.WriteLine("StringCollection elements...");
      foreach (string str in strArr){
         Console.WriteLine(str);
      }
      strCol.AddRange(strArr);
      Console.WriteLine("Element at 5th index = "+strCol[5]);
      Console.WriteLine("Count of strings in StringCollection = " + strCol.Count);
   }
}

Output

This will produce the following output −

StringCollection elements...
A
B
C
D
E
F
G
H
Element at 5th index = F
Count of strings in StringCollection = 8

Example

Let us now 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[] { "100", "200", "100", "400", "500" };
      Console.WriteLine("Array elements...");
      foreach (string res in arr){
         Console.WriteLine(res);
      }
      stringCol.AddRange(arr);
      Console.WriteLine("Total number of elements = "+stringCol.Count);
      stringCol.Remove("100");
      Console.WriteLine("Total number of elements now = "+stringCol.Count);
   }
}

Output

This will produce the following output −

Array elements...
100
200
100
400
500
Total number of elements = 5
Total number of elements now = 4
