Hi all,

I have been trying to use a double array for a simple iteration, however, I seem to have trouble setting values to particular indices. Below, is the code I used. I am getting index out of range exception at the highlighted LOC.

C#

byte[] utf8Bytes = Encoding.Convert(unicode,
                                                utf8,
                                                unicodeBytes);

           
           int k = 1;
         
           int[,] d = new int[k, 3];
           int i = 0;
           int flag = 0;
           foreach (byte b in utf8Bytes)
           {
              
               
               d[k, i] = Convert.ToInt32(b);
               i++;
               if (k < 3)
               {
                   k++;
                   continue;
               }

              

              
           }

what is it that I am doing wrong?

Look at your code, and pay attention to every use of k:

C#

int k = 1;

int[,] d = new int[k, 3];
    d[k, i] = Convert.ToInt32(b);
    if (k < 3)
        k++;

So you start with k = 1, allocate an array with one row by three columns...and then try to access the second row...
C# array indices are zero based: so the array you declared had three elements at [0, 0], [0, 1], and [0, 2]

Quote:
index out of range exception

This error message tells you that you try to use your array with an index out of range.

This is the typical kind of problem easily solved by using a debugger.

- set a breakpoint on the offending line
- run your program in debugger mode
- check the value of variables used to access your array, and compare against the size of your array.
- soon, a bell should start to ring in your mind.
