How to create a StringCollection in C#?
To create a StringCollection in C#, the code is as follows −
Example
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 −
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
