Juan,

More then likely you are having a problem because your byte array is
not full. As such every element that hasn't been assigned a byte will
be treated as 0 which messes things up when you convert the whole
array to a string.

You need to make sure whenever you do an operation on the array you
use the length of the array to limit the elements you are converting.
Example:

byte[] buffer = new byte[2048];
// Put some stuff in the buffer.
int bufferIndex = length of data placed in the buffer
string bufferString = System.Text.Encoding.ASCII.GetString(buffer, 0,
bufferIndex);

>From you code I am not sure what you are trying to do? You already
have a string but you are putting it into a byte array? If possible
you should use a StringBuilder object for string concetentaion
operations, it saves the inefficiency of creating new string objects
for each append.

Regards,

Aaron
