Check if the specified string is in the StringCollection in C#

CsharpServer Side ProgrammingProgramming

To check if the specified string is in 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"));
   }
}

Output

This will produce the following output −

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

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[] { "John", "Tim", "Kevin", "Bradman", "Katie", "Tom", "Nathan" };
      Console.WriteLine("String 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("Katie"));
   }
}

Output

This will produce the following output −

String array elements...
John
Tim
Kevin
Bradman
Katie
Tom
Nathan
Does the specified string is in the StringCollection? = True
