How to determine encoding of a string.

Frank Rizzo

I read a string out of a database, which contains serialized objects.
How can I determine the encoding of the string?

Thanks

Hi,

AFAIK there is no way to determine the encoding of a string, you will have
to save the encoding when you save the string in the first place.

If the datatype that you're using in .Net is a string, then the encoding is
UTF-16. By definition, all .Net strings are UTF-16 encoded.

The only way you can have a different encoding is if you're reading the data
out of the database as a byte array. If you're looking at a byte array, I
don't know of any definitive way to tell the encoding.

I agree. By design, all the strings in .NET is Unicode. The strings can
only be encoded to byte array with other formats. If you need to maintain
the encoding information, you can try to add some bytes at the beginning of
the array.

If anything is unclear, please feel free to let me know.

I don't know exactly how to do this, so I was hoping for some pointers! Another possibility is to encrypt the string using MD5, which would tend to shorten it, but MD5 doesn't produce a number-only...
