Boolean.GetHashCode() Method in C# with Examples

Boolean.GetHashCode() Method is used to return the hash code for this instance.

Syntax: public override int GetHashCode ();

Return Value: This method returns a 32-bit signed integer hash code.

Below programs illustrate the use of Boolean.GetHashCode() Method:

Example 1:

// C# program to demonstrate the
// Boolean.GetHashCode() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring and initializing value1
        bool value1 = true;

        // getting the HashCode
        // using GetHashCode() method
        int value = value1.GetHashCode();

        // Display the HashCode
        Console.WriteLine("HashCode is {0}", value);
    }
}

Output:

HashCode is 1

Example 2:

// C# program to demonstrate the
// Boolean.GetHashCode() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() method
        get(true);
        get(false);
    }

    // defining get() method
    public static void get(bool value1)
    {

        // getting the HashCode
        // using GetHashCode() method
        int value = value1.GetHashCode();

        // Display the HashCode
        Console.WriteLine("HashCode is {0}", value);
    }
}

Output:

HashCode is 1
HashCode is 0
