C#-ASCII,unicode---ShinePans

ASCII碼與Unicode碼的區別

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace AsciiText
{
    class Program
    {
        static void Main(string[] args)
        {
            //默認的是 unicode編碼
            String str = "I live in 中國!";  //Unicode 
            Encoding uni_str = Encoding.Unicode;  //獲取Unicode編碼
            byte[] uni_byte = uni_str.GetBytes(str);
            Console.WriteLine("Unocode:");
            for(int i=1;i{0}", uni_str.GetString(uni_byte));
            //ASCII 編碼
            Encoding ascii_str = Encoding.ASCII;   //獲取ACSII編碼
            byte[] ascii_byte = ascii_str.GetBytes(str);
            Console.Write("ASCII:");
            for(int i=0;i{0}", ascii_str.GetString(ascii_byte));
            Console.ReadLine();
        }
    }
}

結果輸出:

Unocode:
0-32-0-108-0-105-0-118-0-101-0-32-0-105-0-110-0-32-0-45-78-253-86
n 中國!
ASCII:73-32-108-105-118-101-32-105-110-32-63-63-33->I live in ??!

1.

byte [] intBuff = BitConverter.GetBytes(i); // 將 int 轉換成字節數組

2.

byte [] doubleBuff = BitConverter.GetBytes(x); // 將 double 轉換成字節數組

3.

lob.Write(doubleBuff, 0, 8);

x = BitConverter.ToDouble(doubleBuff, 0); // 從字節數組轉換成 double

4.

lob.Write(intBuff, 0, 4);
i = BitConverter.ToInt32(intBuff, 0); // 從字節數組轉換成 int
