Remove all the strings from the StringCollection in C#
To remove all the strings 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", "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 −
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
