Boolean.ToString(IFormatProvider) Method in C#

Boolean.ToString(IFormatProvider) Method is used to convert the value of the current instance to its equivalent string representation that is either “True” or “False”

Syntax:

public string ToString (IFormatProvider provider);

Parameters: This method takes an object of type IFormatProvider which is reserved.

Return Value: This method returns the TrueString if the value of this instance is true, or FalseString if the value of this instance is false.

Example:

// C# program to demonstrate
// Boolean.ToString(IFormatProvider)
// Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // declaring and initializing
        // Boolean value
        bool s1 = true;

        // creating and initializing
        // the object of CultureInfo
        CultureInfo provider = new CultureInfo("en-us");

        // Using the method
        string str = s1.ToString(provider);

        // Display the value
        Console.WriteLine("The Value is {0} and provider is {1}",
                                             str, provider.Name);
    }
}

Output:

The Value is True and provider is en-US

Note: The provider parameter is reserved as it will not contribute anything in the execution of this method. This means this method, unlike most methods with a provider parameter, does not reflect culture-specific settings.
