    <p>I am trying to get 2D array representing distances between specific cities using LINQ. It is up to me to pick proper XML representation of the problem. At first, I used MatLAB-style array to represent dependencies, which looked like this:</p> <pre><code>&lt;cityMap&gt; [-, 2, 3, 4, 5, 6, 7, 8; 1, -, 3, 4, 5, 6, 7, 8; 1, 2, -, 4, 5, 6, 7, 8; 1, 2, 3, -, 5, 6, 7, 8; 1, 2, 3, 4, -, 6, 7, 8; 1, 2, 3, 4, 5, -, 7, 8; 1, 2, 3, 4, 5, 6, -, 8; 1, 2, 3, 4, 5, 6, 7, -] &lt;/cityMap&gt; </code></pre> <p>It was very convenient to get this matrix from single LINQ query and parse it in C#, but from the XML point of view it was rather not correct (multiple data in one tag). Now I am trying something like this:</p> <pre><code>&lt;salesman&gt; &lt;salesmanNumber&gt;10&lt;/salesmanNumber&gt; &lt;cities&gt; &lt;city id="1"&gt; &lt;headquarter&gt;1&lt;/headquarter&gt; &lt;distance toCity="2"&gt;2&lt;/distance&gt; &lt;distance toCity="3"&gt;3&lt;/distance&gt; &lt;distance toCity="4"&gt;4&lt;/distance&gt; &lt;distance toCity="5"&gt;5&lt;/distance&gt; &lt;distance toCity="6"&gt;6&lt;/distance&gt; &lt;/city&gt; &lt;city id="2"&gt; &lt;headquarter&gt;1&lt;/headquarter&gt; &lt;distance toCity="1"&gt;1&lt;/distance&gt; &lt;distance toCity="3"&gt;3&lt;/distance&gt; &lt;distance toCity="4"&gt;4&lt;/distance&gt; &lt;distance toCity="5"&gt;5&lt;/distance&gt; &lt;distance toCity="6"&gt;6&lt;/distance&gt; [....] &lt;/cities&gt; &lt;/salesman&gt; </code></pre> <p>And two questions emerge: 1. Is this correct form of representing an array? 2. How to read this data with LINQ query so that I will be able to parse it to array?</p>

    2. COThere is nothing wrong by representing an array as an element value with comma separated values on multiple line too. You just need to format/parse the value by using `string.Join()` and `string.Split()` methods

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.
