原文:https://www . geesforgeks . org/c-sharp-char-gethashcode-method-with-examples/

此方法用于返回此实例的哈希代码。

语法:

public override int GetHashCode ();

返回值:这个方法返回一个 32 位有符号整数哈希码。

以下程序说明了字符的使用。GetHashCode() 方法:

例 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

例 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
