Octal To ASCII

This algorithm converts octal numbers to ASCII code.

									public static string OctalToASCII(string oct)
{
	string ascii = string.Empty;

	for (int i = 0; i < oct.Length; i += 3)
	{
		ascii += (char)OctalToDecimal(oct.Substring(i, 3));
	}

	return ascii;
}

private static int OctalToDecimal(string octal)
{
	int octLength = octal.Length;
	double dec = 0;

	for (int i = 0; i < octLength; ++i)
	{
		dec += ((byte)octal[i] - 48) * Math.Pow(8, ((octLength - i) - 1));
	}

	return (int)dec;
}

Example

									string data = "120162157147162141155155151156147040101154147157162151164150155163";
string value = OctalToASCII(data);
