C# Convert a string to ASCII bytes
提问by Coolguy
I have a string:
我有一个字符串：
LogoDataStr = "ABC0000"
I want to convert to ASCII bytes and the result should be:
我想转换为 ASCII 字节，结果应该是：
LogoDataBy[0] = 0x41;
LogoDataBy[1] = 0x42;
LogoDataBy[2] = 0x43;
LogoDataBy[3] = 0x30;
LogoDataBy[4] = 0x30;
LogoDataBy[5] = 0x30;
LogoDataBy[6] = 0x30;
I've tried using this way:
我试过用这种方式：
byte[] LogoDataBy = ASCIIEncoding.ASCII.GetBytes(LogoDataStr);
But the result I get is this:
但我得到的结果是这样的：
LogoDataBy[0] = 0x41;
LogoDataBy[1] = 0x42;
LogoDataBy[2] = 0x43;
LogoDataBy[3] = 0x00;
LogoDataBy[4] = 0x00;
LogoDataBy[5] = 0x00;
LogoDataBy[6] = 0x00;
Is there any wrong with my coding?
我的编码有问题吗？

This code
这段代码
class Program
{
static void Main(string[] args)
{
byte[] LogoDataBy = ASCIIEncoding.ASCII.GetBytes("ABC000");
}
}
produces expected output
产生预期输出
Double check your code and the value of the string before you read ASCII bytes.
在读取 ASCII 字节之前，请仔细检查您的代码和字符串的值。

Just throwing:
只是扔：
Encoding.ASCII.GetBytes("ABC0000").Dump();
Into LinqPAD gives an output of (decimal):
进入 LinqPAD 给出（十进制）的输出：
Byte[] (7 items)
65
66
67
48
48
48
48
字节[] (7 项)
65
66
67
48
48

So I'm not sure how you're getting 0x00...
所以我不确定你是如何得到 0x00 的...

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;
}
}
This is how i would do it. JUST IF Encoding.ASCII.GetBytes() would return wrong values.
这就是我要做的。只是如果 Encoding.ASCII.GetBytes() 会返回错误的值。
