Code:

internal static byte CalculateByteStuffingLength(byte[] dataLinkLayerFrame)
{
    byte resultat = 0;

    foreach (byte b in dataLinkLayerFrame)
    {
        if ((b == WriteStartByte) || (b == ReadStartByte) || (b == Stop) || (b == Acknowledgement) || (b == Stuff))
            resultat += 2;
        else
            resultat++;
    }

    return resultat;
}

Test:

[TestMethod]
public void CalculateByteStuffingLengthTest()
{
    byte[] dataLinkLayerFrame = new byte[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    byte expected = 11; 
    byte actual = CommandBase.CalculateByteStuffingLength(dataLinkLayerFrame);

    Assert.AreEqual(expected, actual);
