System.Text.Encoding 的用法 - 字串與 byte 互轉

 

C# 範例為

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = "a";

            byte[] b = System.Text.Encoding.GetEncoding(950).GetBytes(input);
            foreach (var item in b)
            {
                Console.WriteLine(item);
            }
            string output = System.Text.Encoding.GetEncoding(950).GetString(b);
            Console.WriteLine("output = " + output);

            Console.WriteLine();
            byte[] d = System.Text.Encoding.Default.GetBytes(input);
            foreach (var item in d)
            {
                Console.WriteLine(item);
            }
            string output2 = System.Text.Encoding.Default.GetString(d);
            Console.WriteLine("output2 = " + output2);

            Console.ReadKey();
        }
    }
}

 

VB.NET 範例為

Module Module1

    Sub Main()
        Dim abData() As Byte

        Dim Str As String

        Dim i As Long

        Str = "Hello world!"

        ' Convert string to bytes

        abData = System.Text.Encoding.Default.GetBytes(Str)

        For i = 0 To UBound(abData)

            Console.WriteLine(Hex(abData(i)) & "='" & Chr(abData(i)) & "'")

        Next

        ' Convert bytes to string

        Str = System.Text.Encoding.Default.GetString(abData)

        Console.WriteLine("'" & Str & "'")

        Console.ReadKey()
    End Sub

End Module
