Convert from byte array to string and Split String

Question

Let's say I have a byte array

Byte[] arr;

Then I will convert the array to string 1st.

String inputString = "";
foreach (Byte b in arr)
{
   if (b != 0)
      inputString += (Char) b;
   else inputString += " ";
}

Let's say the string is:

inputString  = @"C:\Program Files\Test C:\Users\User A\AppData\Local\Temp C 32323 C:\Program Files\Test\Temp";

I want it to be split into 4 strings that look like below:

C:\Program Files\Test \\position 0 = test folder
C:\Users\User A\AppData\Local\Temp \\position 1 = windows temp folder
C 32323 \\position 2 = a name. It can be C2313 or C 2312 or whatever string
C:\Program Files\Test\Temp \\position 3 = temp for test folder
\\ position can change by me...

every string in between will be split by space. That's mean I can use .Split(' '). However, as you know some of the path has space in between, 'C:\Program Files\Test' is an example.

How can I get the values I want?

Are you sure the original byte[] didn't have a \0 between the various paths? Try changing inputString += " " to inputString += "|" — xanatos

substrings C:\Users\User A\AppData\Local\Temp and C 32323? following the pattern, it should be C:\Users\User A\AppData\Local\Temp C 32323 folder, isn't it? — ASh

Sorry, this doesn't make it any clearer. If any string can be considered as valid, how can you decide if Files\Test is a part of C:\Program Files\Test or if it's a standalone string (and so is C:\Program)? — Zohar Peled

Try doing this:

byte[] arr = ...

string[] inputStrings = Encoding.GetEncoding("iso-8859-1").GetString(arr).Split('\0');

And see the result.

the array inputStrings contains a lot of empty strings.

Try posting the result array... I can't debug with this informations.

@kingjia You could post the base64 version of the byte[] arr: string arrToString = Convert.ToBase64String(arr)

Problem solved. Thanks for your advise to use inputString += "|".

Here is my answer. Thanks @xanatos for the advise.

String inputString = "";
bool isRepeat = false;
foreach (Byte b in arr)
{
   if (b != 0)
   {
      inputString += (Char)b;
      isRepeat = false;
   }
   else
   {
      if (!isRepeat)
      {
         inputString += "|";
         isRepeat = true;
      }
   }               
}
