Question

I am looking to write the Oracle function rawtohex in C#.
I am looking at existing code that has been written and would like to be confirm if it is accurate.

public static string AsHexString1(this char[] chars)
{
    StringBuilder sb = new StringBuilder();

    foreach (var ch in chars)
    {
        int lowNibble = (int)ch % 16;
        int highNibble = (int)ch / 16;

        sb.Append(highNibble <= 9 ? highNibble.ToString() : ((char)('A' + (highNibble - 10))).ToString());
        sb.Append(lowNibble <= 9 ? lowNibble.ToString() : ((char)('A' + (lowNibble - 10))).ToString());
    }

    return sb.ToString();
}

Thanks.

As far as I know, RawToHex should be something similar to this:

public static string RawToHex(byte[] data)
{
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < data.Length; i++)
        sb.AppendFormat("{0:X2}", data[i]);
    return sb.ToString();
}

I’m not sure why you’re using a char array as input, since it’s RAW data…
