Convert char[] to byte[] and vice versa

What is the best way to convert char[] to byte[] in C# 2010?

Please note that we do not know in advance the format of a single char. It can either be ASCII or Unicode or UTF-8 or UTF-16.

Is there one universal conversion to overcome this?

And what is the vice versa conversion in this case, say to Unicode?

What is C# 2010? There is no such thing! .NET has version numbers as in 1.1, 2.0, 3.0, 3.5, 4.0 etc.

Solution 3

There are more solutions.
The first is:

C#

byte[] byteArray = Encoding.yourEncoding.GetBytes(charArray1);

More information about this method:

The second is:

C#

byte[] byteArray = Convert.FromBase64CharArray(charArray1,0,charArray1.Length);

More information about this method: http://msdn.microsoft.com/en-us/library/system.convert.frombase64chararray.aspx[^]

Hope this helps.

For the third time, I have no information about the type of encoding the array has. Anyway, the issue has been resolved. Cheers!

You can try all encodings, and then
you'll see what's the best.

That approach works only if you know the type of encoding, which I don't, as I clearly stated. I decided to re-post the problem that I'm having closer to what it actually is: CLOB: char[] serialization

Solution 2

Turns out I didn't need it after all. I was trying to serialize char[] via a string, for which I could simply call:

Serialization:

- Convert char[] to String using String(char[]) constructor;

De-serialization:

- Call String.ToCharArray();
