How to convert Byte[] into String?

[EOS]

Hi,

I would like to ask on how to convert array of bytes, Byte[] into String?

I tried StringIwant = System.Convert.ToString(byteData);

but it actually return "System.Byte[]" rather than convert the data I wanted
into string.

I guess it should be a rather simple question.

By the way, I am using compact framework for PDA.

Thanks in advance. : )

You actually want:

string StringIWant = BitConverter.ToString(byteData);

Hi,

It's very simple, you have to use one of the encoding classes provided in
the framework. You see, depending of how you generated the bytes[] from the
original string you get a different set of data, UNICODE are stored as two
bytes, where ASCII are encoded as 1 byte.

Once you know this you use osmething like ASCIIEncoding.GetString( byte[] );

cheers,

If you need something more complex that takes into account different
encoding such as ascii vs. unicode, then use something like
Encoding.GetString(...).

You actually want:

string StringIWant = BitConverter.ToString(byteData);

Actually what I wanted is rather simple.

In C/C++, it is;

byte byteData[500] = .....

CString szMyString = (CString) byteData

It is that simple and straight forward because what is inside the byte array
is exactly the same char[]. Even a simple memcpy will work.

Any ideas on how to implement these simple object convertion in C#?

By the way, I am develope on Compact .NET which is on PDA.

Hi,

It's as simple in C#:

byte byteData[500] = ...

string s = Encoding..ASCII.GetString( byteData);

Hmm... that sounds unlikely, as a byte array has one byte per entry,
but a char array has two bytes per entry in .NET.

It's all a case of working out what encoding you're using. I suspect
that Encoding.Default.GetString(data) is what you want (or possibly the
overload which takes an index and size, if your byte array is longer
than the "real" data in it; you don't want to include the null
terminator, for instance).
