What is the best way to convert a bytearray into a string ?

I thought I could do it using the code below, but is there anything
faster/easier than this? Thanks!

Chris



int aLength = 100000;
byte[] myByteArray = new byte[aLength ];
string myString = "";


for (int i=0; i<aLength ; i++)
{
myString += (char) myByteArray;
}

//work with this new string: cut out every char=='A'
myString.split('A');

....
 
I've been doing this is VC# Express 2005 Beta:

ASCIIEncoding AE = new ASCIIEncoding();
string TextString = AE.GetString(byte-array);

Don't know if it works in other versions, so you'll need to check in your
specific VS release.

Chris,

Do you know the encoding of the string? If so, then use the appropriate
encoder class (AsciiEncoder, UnicodeEncoder, etc, etc).

You would just call the GetString method on the encoder class at that
point.

Hope this helps.
 
First of all you are assuming that your array of bytes is an array of
chars, which might be risky.

However, String has a constructor that takes an array of characters.

That all depends on the source of the byte array. What kind of data
does it represent? If it's text data, what encoding was used to encode
it? If it's arbitrary binary data (eg an mp3 file) you need to use
something like base64.

By the way, concatenating strings in a loop like that is a
performance-killer. See

information.
