C# | Char.GetHashCode() Method with Examples
  • Last Updated : 19 Dec, 2019

This 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 Char.GetHashCode() Method:

Example 1:






// C# program to demonstrate
// Char.GetHashCode() Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // declaring and initializing char
        char ch1 = 'B';
  
        // checking condition
        // using Equals() Method
        int val = ch1.GetHashCode();
  
        // Display Hashcode
        Console.WriteLine("Hashcode :- {0}", val);
    }
}


Output:

Hashcode :- 4325442

Example 2:




// C# program to demonstrate
// Char.GetHashCode() Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // calling hash() Method
        hash('a');
        hash('b');
        hash('c');
        hash('x');
        hash('y');
        hash('z');
    }
  
    // Defining hash() Method
    public static void hash(char ch)
    {
        // checking condition
        // using Equals() Method
        int val = ch.GetHashCode();
  
        // Display Hashcode
        Console.WriteLine("Hashcode of " + ch +
                                " :- {0}", val);
    }
}


Output:

Hashcode of a :- 6357089
Hashcode of b :- 6422626
Hashcode of c :- 6488163
Hashcode of x :- 7864440
Hashcode of y :- 7929977
Hashcode of z :- 7995514
