Converting EBCDIC to ASCII in C#

Question

I've been trying to convert a string containing EBCDIC characters to ASCII, this is my code so far:

string data = "F2F1F0F2F2F5F4";
Encoding ascii = Encoding.ASCII;
Encoding ebcdic = Encoding.GetEncoding("IBM037");
byte[] ebcdicData = ebcdic.GetBytes(data);

// Convert to ASCII
byte[] ebcdicDataConverted = Encoding.Convert(ebcdic, ascii, ebcdicData);
string sample = ascii.GetString(ebcdicDataConverted);

But I was expecting that the variable sample contained this value: 2102254 Instead, it shows the same value as data F2F1F0F2F2F5F4

Maybe I'm not understanding how this works, or I'm just burnt out, this page contains the conversion table that:

translates 8-bit EBCDIC characters to 7-bit ASCII

Is the Enconding that I'm using the right one? Am I doing something wrong?

Thanks

Answer 1

I converted de string to byte using a for like this:

byte[] ebcdicData = new byte[data.Length / 2];
    for (int i = 0; i < ebcdicData.Length; i++)
    {
        string chunk = data.Substring(i * 2, 2);
        ebcdicData[i] = Convert.ToByte(chunk, 16);
    }

This way it worked. Idk why GetBytes() does something different, I will take a look at the documentation
