C＃将字符串转换为ASCII字节

Question

我有一个字符串：

LogoDataStr = "ABC0000"

我想转换为ASCII字节，结果应为：

LogoDataBy[0] = 0x41;
LogoDataBy[1] = 0x42;
LogoDataBy[2] = 0x43;
LogoDataBy[3] = 0x30;
LogoDataBy[4] = 0x30;
LogoDataBy[5] = 0x30;
LogoDataBy[6] = 0x30;

我尝试过这种方式：

byte[] LogoDataBy = ASCIIEncoding.ASCII.GetBytes(LogoDataStr);

但我得到的结果是：

LogoDataBy[0] = 0x41;
LogoDataBy[1] = 0x42;
LogoDataBy[2] = 0x43;
LogoDataBy[3] = 0x00;
LogoDataBy[4] = 0x00;
LogoDataBy[5] = 0x00;
LogoDataBy[6] = 0x00;

我的编码有什么问题吗？

Answer 1

此代码

class Program
{
    static void Main(string[] args)
    {
        byte[] LogoDataBy = ASCIIEncoding.ASCII.GetBytes("ABC000");
    }        
}

产生预期产出

在读取ASCII字节之前仔细检查代码和字符串的值。

Answer 2

扔掉：

Encoding.ASCII.GetBytes("ABC0000").Dump();

进入LinqPAD会得到（十进制）的输出：

  

Byte []（7项）
  65个
  66个
  67个
  48个
  48个
  48个
  48

所以我不确定你是怎么得到0x00 ......

Answer 3

    class CustomAscii
    {
        private static Dictionary<char, byte> dictionary;

        static CustomAscii()
        {
            byte numcounter = 0x30;
            byte charcounter = 0x41;
            byte ucharcounter = 0x61;
            string numbers = "0123456789";
            string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            string uchars = "abcdefghijklmnopqrstuvwxyz";
            dictionary = new Dictionary<char, byte>();
            foreach (char c in numbers)
            {
                dictionary.Add(c, numcounter++);
            }
            foreach (char c in chars)
            {
                dictionary.Add(c, charcounter++);
            }
            foreach (char c in uchars)
            {
                dictionary.Add(c, ucharcounter++);
            }
        }

        public static byte[] getCustomBytes(string t)
        {
            int iter = 0;
            byte[] b = new byte[t.Length];
            foreach (char c in t)
            {
                b[iter] = dictionary[c];
                //DEBUG: Console.WriteLine(b[iter++].ToString());
            }

            return b;
        }
    }

我就是这样做的。 JUST IF Encoding.ASCII.GetBytes（）会返回错误的值。
