Boolean.Equals(Boolean) Method in C#

The Boolean.Equals(Boolean) method in C# returns a value indicating whether this instance is equal to a specified Boolean object. This method compares the current Boolean instance with another Boolean value and returns true if they are equal, otherwise false.

Syntax

Following is the syntax −

public bool Equals(bool obj);

Parameters

• obj − A Boolean value to compare to this instance.

Return Value

This method returns true if obj has the same value as this instance; otherwise, false.

Example

Let us see an example to implement the Boolean.Equals(Boolean) method −

using System;

public class Demo {
    public static void Main() {
        bool b1 = false;
        bool b2 = true;
        bool res = b1.Equals(b2);
        
        if (res == true)
            Console.WriteLine("b1 equal to b2");
        else
            Console.WriteLine("b1 not equal to b2");
    }
}

The output of the above code is −

b1 not equal to b2

Using Equals() with Same Values

Here's another example showing the method when comparing equal Boolean values −

using System;

public class Demo {
    public static void Main() {
        bool b1 = true;
        bool b2 = true;
        bool b3 = false;
        bool b4 = false;
        
        Console.WriteLine("b1.Equals(b2): " + b1.Equals(b2));
        Console.WriteLine("b3.Equals(b4): " + b3.Equals(b4));
        Console.WriteLine("b1.Equals(b3): " + b1.Equals(b3));
    }
}

The output of the above code is −

b1.Equals(b2): True
b3.Equals(b4): True
b1.Equals(b3): False

Comparison with == Operator

The Equals() method produces the same result as the equality operator (==) for Boolean values −

using System;

public class Demo {
    public static void Main() {
        bool x = true;
        bool y = false;
        
        Console.WriteLine("Using Equals(): " + x.Equals(y));
        Console.WriteLine("Using == operator: " + (x == y));
        
        Console.WriteLine("Using Equals(): " + x.Equals(true));
        Console.WriteLine("Using == operator: " + (x == true));
    }
}

The output of the above code is −

Using Equals(): False
Using == operator: False
Using Equals(): True
Using == operator: True

Conclusion

The Boolean.Equals(Boolean) method provides a straightforward way to compare Boolean values. While it functions identically to the == operator for Boolean comparisons, it follows the standard Equals() pattern used across .NET types for consistency in object-oriented programming.
