HEX String to Chinese String

Question

I have the following code to convert from HEX to ASCII.

//Hexadecimal to ASCII Convertion
private static string hex2ascii(string hexString)
{
    MessageBox.Show(hexString);
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i <= hexString.Length - 2; i += 2)
    {
        sb.Append(Convert.ToString(Convert.ToChar(Int32.Parse(hexString.Substring(i, 2), System.Globalization.NumberStyles.HexNumber))));
    }
    return sb.ToString();
}

input hexString = D3FCC4A7B6FABBB7

output return = Óüħ¶ú»·

The output that I need is 狱魔耳环, but I am getting Óüħ¶ú»· instead. How would I make it display the correct string?

Answer 1

First, convert the hex string to a byte[], e.g. using code at How do you convert Byte Array to Hexadecimal String, and vice versa?. Then use System.Text.Encoding.Unicode.GetString(myArray) (use proper encoding, might not be Unicode, but judging from your example it is a 16-bit encoding, which, incidentally, is not "ASCII", which is 7-bit) to convert it to a string.
