au3 如何校验某个文件的crc16值啊非crc32值

today2004

如题如果校验某个文件的crc值啊 请注意是crc16值 不是crc32值  感谢

today2004

高手出现啊

貌似crc没有具体的值，crc32、crc16等才是具体的值

today2004

就是要crc16的

rchockxm

Dim $avTest[5] = ["Test line 1.", "abcdefghijklmnopqrstuvwxyz01234567890", 0xFEDCBA98, "", StringToBinary("Binary test.")]
$sMsg = ""
For $n = 0 To UBound($avTest) - 1
    $sMsg &= $avTest[$n] & " CRC16 = " & _StringCrc16($avTest[$n]) & @CRLF
Next
MsgBox(64, "StringCrc16 Test", $sMsg)
