StringBuilder.Equals Method is used to check whether this instance is equal to a specified object.

Syntax: public bool Equals (System.Text.StringBuilder sb); Here, sb is an object to compare with this instance, or null. Return Value: It will return true if this instance and sb have an equal string, Capacity, and MaxCapacity values; otherwise, false.

Example 1: 

csharp

// C# program to if a StringBuilder object
// is equal to another StringBuilder object
using System;
using System.Text;
 
class Geeks {
 
    // Main Method
    public static void Main(String[] args)
    {
 
        // Create a StringBuilder object
        // with a String passed as parameter
        StringBuilder st1 = new StringBuilder("GeeksforGeeks");
 
        // Checking whether st1 is
        // equal to itself or not
        Console.WriteLine(st1.Equals(st1));
    }
}

                    
Output:
True

Example 2: 

csharp

// C# program to if a StringBuilder object
// is equal to another StringBuilder object
using System;
using System.Text;
 
class Geeks {
 
    // Main Method
    public static void Main(String[] args)
    {
 
        // Create a StringBuilder object
        // with a String passed as parameter
        StringBuilder st1 = new StringBuilder("GeeksforGeeks");
 
        // Create a StringBuilder object
        // with a String passed as parameter
        StringBuilder st2 = new StringBuilder("GFG");
 
        // Checking whether st1 is
        // equal to st2 or not
        Console.WriteLine(st1.Equals(st2));
 
        // Create a StringBuilder object
        // with a String passed as parameter
        StringBuilder st3 = new StringBuilder();
 
        // Assigning st2 to st3
        st3 = st2;
 
        // Checking whether st3 is
        // equal to st2 or not
        Console.WriteLine(st3.Equals(st2));
    }
}

                    
Output:
False
True
