Check If Two StringCollection Objects Are Equal in C#

To check if two StringCollection objects are equal, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringCollection strCol1 = new StringCollection();
      strCol1.Add("Accessories");
      strCol1.Add("Books");
      strCol1.Add("Electronics");
      Console.WriteLine("StringCollection1 elements...");
      foreach (string res in strCol1) {
         Console.WriteLine(res);
      }
      StringCollection strCol2 = new StringCollection();
      strCol2.Add("Accessories");
      strCol2.Add("Books");
      strCol2.Add("Electronics");
      Console.WriteLine("StringCollection2 elements...");
      foreach (string res in strCol1) {
         Console.WriteLine(res);
      }
      Console.WriteLine("Both the String Collections are equal? = "+strCol1.Equals(strCol2));
   }
}

Output

This will produce the following output −

StringCollection1 elements...
Accessories
Books
Electronics
StringCollection2 elements...
Accessories
Books
Electronics
Both the String Collections are equal? = False

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringCollection strCol1 = new StringCollection();
      strCol1.Add("Accessories");
      strCol1.Add("Books");
      strCol1.Add("Electronics");
      Console.WriteLine("StringCollection1 elements...");
      foreach (string res in strCol1) {
         Console.WriteLine(res);
      }
      StringCollection strCol2 = new StringCollection();
      strCol2.Add("Accessories");
      strCol2.Add("Books");
      strCol2.Add("Electronics");
      Console.WriteLine("StringCollection2 elements...");
      foreach (string res in strCol1) {
         Console.WriteLine(res);
      }
      Console.WriteLine("Both the String Collections are equal? = "+strCol1.Equals(strCol2));
      StringCollection strCol3 = new StringCollection();
      strCol3 = strCol2;
      Console.WriteLine("Is StringCollection3 equal to StringCollection2? = "+strCol3.Equals(strCol2));
   }
}

Output

This will produce the following output −

StringCollection1 elements...
Accessories
Books
Electronics
StringCollection2 elements...
Accessories
Books
Electronics
Both the String Collections are equal? = False
Is StringCollection3 equal to StringCollection2? = True
