C# | Byte。GetHashCode()方法

原文:https://www . geesforgeks . org/c-sharp-byte-gethashcode-method/

此方法用于返回给定字节的哈希代码。语法:

public override int GetHashCode ();

返回值:该方法返回当前字节的哈希码。下面的程序说明了字节的使用。GetHashCode() 方法: 例 1:

c sharp . c sharp . c sharp . c sharp

// C# program to demonstrate
// Byte.GetHashCode Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring and initializing val
        long val = 83935;

        // converting long array into bytes
        byte[] bytes = BitConverter.GetBytes(val);

        // getting hashcode
        // using GetHashCode() method
        for (int i = 0; i < bytes.Length; i++) {

            // getting hash code of a single byte
            int j = bytes[i].GetHashCode();

            Console.WriteLine("Hashcode: {0}", j);
        }
    }
}

Output:

Hashcode: 223
Hashcode: 71
Hashcode: 1
Hashcode: 0
Hashcode: 0
Hashcode: 0
Hashcode: 0
Hashcode: 0

例 2:

c sharp . c sharp . c sharp . c sharp

// C# program to demonstrate
// Byte.GetHashCode Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        check((long)8543, "long");
        check((int)8543, "int");
        check((byte)85, "byte");
    }

    // Defining the check method
    public static void check(long val, string name)
    {

        // converting long array into bytes
        byte[] bytes = BitConverter.GetBytes(val);

        // getting hashcode
        // using GetHashCode() method
        Console.Write(name + " hashcode:- ");
        for (int i = 0; i < bytes.Length; i++) {

            // getting hash code of a single byte
            int j = bytes[i].GetHashCode();
            Console.Write("{0} ", j);
        }
        Console.WriteLine("");
    }

    // Defining the check method
    public static void check(int val, string name)
    {

        // converting long array into bytes
        byte[] bytes = BitConverter.GetBytes(val);

        // getting hashcode
        // using GetHashCode() method
        Console.Write(name + " Hashcode: ");
        for (int i = 0; i < bytes.Length; i++) {

            // getting hash code of a single byte
            int j = bytes[i].GetHashCode();
            Console.Write("{0} ", j);
        }
        Console.WriteLine("");
    }

    // Defining the check method
    public static void check(byte val, string name)
    {

        // converting long array into bytes
        byte[] bytes = BitConverter.GetBytes(val);

        // getting hashcode
        // using GetHashCode() method
        Console.Write(name + " hashcode:- ");
        for (int i = 0; i < bytes.Length; i++) {

            // getting hash code of a single byte
            int j = bytes[i].GetHashCode();
            Console.Write("{0} ", j);
        }
        Console.WriteLine("");
    }
}

Output:

long hashcode:- 95 33 0 0 0 0 0 0 
int Hashcode: 95 33 0 0 
byte hashcode:- 85 0
