C# | Check if two StringCollection objects are equal Last Updated : 01 Feb, 2019 Comments Improve Suggest changes Like Article Like Report Equals(Object) Method which is inherited from the Object class is used to check if a specified StringCollection object is equal to another StringCollection object or not. Syntax: public virtual bool Equals (object obj); Here, obj is the object which is to be compared with the current object. Return Value: This method return true if the specified object is equal to the current object otherwise it returns false. Below programs illustrate the use of above-discussed method: Example 1: CSharp // C# code to check if two // StringCollections are equal or not using System; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // creating a StringCollection named myCol StringCollection myCol = new StringCollection(); // Adding elements in StringCollection myCol.Add("A"); myCol.Add("B"); myCol.Add("C"); myCol.Add("D"); myCol.Add("E"); // Checking whether myCol is // equal to itself or not Console.WriteLine(myCol.Equals(myCol)); } } Output: True Example 2: CSharp // C# code to check if two // StringCollections are equal or not using System; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // creating a StringCollection named my1 StringCollection my1 = new StringCollection(); // Adding elements in StringCollection my1.Add("GFG"); my1.Add("Noida"); my1.Add("DS"); my1.Add("Geeks"); my1.Add("Classes"); // Creating a StringCollection named my2 StringCollection my2 = new StringCollection(); my2.Add("Australia"); my2.Add("Belgium"); my2.Add("Netherlands"); my2.Add("China"); my2.Add("Russia"); my2.Add("India"); // Checking whether my1 is // equal to my2 or not Console.WriteLine(my1.Equals(my2)); // Creating a new StringCollection StringCollection my3 = new StringCollection(); // Assigning my2 to my3 my3 = my2; // Checking whether my3 is // equal to my2 or not Console.WriteLine(my3.Equals(my2)); } } Output: False True Note: If the current instance is a reference type, the Equals(Object) method checks for reference equality.
