接續之前關於PackBCD格式的介紹，利用Convert.ToString強大的功能，將數值資料轉為2進制輸出，觀察PackBCD格式與一般數值格式的差異

輸入資料>=10開始出現差異，因為10被拆成1與0，1被儲存於高四位，0被儲存於低四位
Convert.ToString(1,2).PadLeft(8,'0')
"00000001"
Convert.ToString(9,2).PadLeft(8,'0')
"00001001"
Convert.ToString(10,2).PadLeft(8,'0')
"00001010"
Convert.ToString(PackBCDConverter.ToPackBCD(1),2).PadLeft(8,'0')
"00000001"
Convert.ToString(PackBCDConverter.ToPackBCD(9),2).PadLeft(8,'0')
"00001001"
Convert.ToString(PackBCDConverter.ToPackBCD(10),2).PadLeft(8,'0')
"00010000"

98被拆成9與8，9被儲存於高四位，8被儲存於低四位
Convert.ToString(8,2).PadLeft(8,'0')
"00001000"
Convert.ToString(9,2).PadLeft(8,'0')
"00001001"
Convert.ToString(98,2).PadLeft(8,'0')
"01100010"
Convert.ToString(PackBCDConverter.ToPackBCD(98),2).PadLeft(8,'0')
"10011000"

單元測試正常

在不穩定的網路環境上，收到的資料可能會發生位元錯誤(bit errors)，或稱為封包錯誤(packet error)，此時也會把原始資料轉為16進制(Convert.ToString(X,16))或2進制(Convert.ToString(X,2))輸出，觀察尋找發生錯誤的位址
