    <p>This is my filing function that takes data from the file and places it in the array:</p> <pre><code>public void populate_grid_by_file() { String store_data_from_file = string.Empty; try { using (StreamReader reader = new StreamReader("data.txt")) { store_data_from_file = reader.ReadToEnd().ToString(); } } catch (Exception e) { Console.WriteLine(e.Message); } string[] line = store_data_from_file.Split(new char[] { '\n' }, StringSplitOptions.RemoveEmptyEntries); for (int i = 0; i &lt; line.Length; i++) { string[] alphabet = store_data_from_file.Split(new char[] {' '}, StringSplitOptions.RemoveEmptyEntries); for (int j = 0; j &lt; alphabet.Length; j++) { Sodoku_Gri[i, j] = alphabet[j]; } } } </code></pre> <p>Here is whats written in the file:</p> <pre>1--2--3-- 3-4-4-5-- -7-3-4--- 7--5--3-6 --7---4-- 3-2--4-5- ------3-- 2-6--7--- 4---4--3-</pre> <p>This is what I want it to print:</p> <pre>1 - - 2 - - 3 - - 3 - 4 - 4 - 5 - - - 7 - 3 - 4 - - - 7 - - 5 - - 3 - 6 - - 7 - - - 4 - - 3 - 2 - - 4 - 5 - - - - - - - 3 - - 2 - 6 - - 7 - - - 4 - - - 4 - - 3 - </pre> <p>I thought of doing it this way:</p> <pre><code>public void display_grid() { for (int row = 0; row &lt; Sodoku_Gri.GetLength(0); row++) { for (int col = 0; col &lt; Sodoku_Gri.GetLength(1); col++) { Console.Write(Sodoku_Gri[row, col]); Console.Write(" "); } Console.WriteLine(); } } </code></pre> <p>I just can't understand why the 2d array printed 9 times with additional ------------ in the last row!</p> <p>It should be a 2d array with spacing between each element like I showed the data in the file but that is without spacing.</p>

    1. COI don't understand the question: The only difference between what *is* written and what *should be* written seem to be the linebreaks, that are apparently created by your call `Console.WriteLine();`. Where are there any "additional --------"?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
