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:

   // 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:

   // 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.
