Remove the first occurrence from the StringCollection in C#
To remove the first occurrence from the StringCollection, the code is as follows −
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
Example
Let us see another example −
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection stringCol = new StringCollection(); String[] arr = new String[] { "10", "20", "30", "40", "50", "60", "70", "80" }; 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("50"); stringCol.Remove("60"); stringCol.Remove("70"); Console.WriteLine("Total number of elements now = "+stringCol.Count); } }
Output
This will produce the following output −
Array elements... 10 20 30 40 50 60 70 80 Total number of elements = 8 Total number of elements now = 5
