Urgent: Correcting a basic syntax error

Can anyone find why the following error is occuring in the following piece of C# code:

private ArrayList tot = new ArrayList(20);
private ArrayList data = new ArrayList(20);

private void tokenizeline(String line,int i)
      tot[i] = line;
      StringTokenizer tk = new StringTokenizer(tot[i].ToString(),"\t");
      data[i] = new String[tk.CountTokens()];
      for(int j=0;tk.HasMoreTokens();j++)
            data[i][j] = tk.NextToken();

Error at data[i][j]: Cannot apply indexing with [] to an expression of type 'object'

Try to use casting, something like this:

((String[])data[i])[j] = tk.NextToken();

Yess...it works.......and what I did is somethin a little bit longer:

String[] temp = new String[tk.CountTokens()];
for(int j=0;tk.HasMoreTokens();j++)
      temp[j] = tk.NextToken();
data[i] = temp;

Yours is better....Thanks!!!
