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:
csharp
// 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 GetHashCode() Method
int val = ch1.GetHashCode();
// Display Hashcode
Console.WriteLine("Hashcode :- {0}", val);
}
}
Output:
Hashcode :- 4325442
Example 2:
csharp
// 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 GetHashCode() 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
