Body
Any method that has a type other than void must return an object of that type. So DisplayHeaders must return an integer array. <pre><code>private static int[] DisplayHeaders(string[] headers) </code></pre> <code>private</code> - access modifier; indicates this method can only be called from within the class <code>static</code> - static modifier; this method does not need an instance to be called <code>int[]</code> - return type; this is the type of the object that this method will return <code>DisplayHeaders</code> - method name; this is how you refer to this method <code>(string[] headers)</code> - parameters; this indicates which arguments you need to pass to the method We can infer from the method summary that its implementation may look something like this: <pre><code> /// <summary> /// Displays the column headers /// </summary> /// <returns>returns an array of column widths</returns> private static int[] DisplayHeaders(string[] headers) { // builds a new int array with the same // number of elements as the string array parameter int[] widths = new int[headers.Length]; for (int i = 0; i < headers.Length; i++) { Console.WriteLine(headers[i]); // displays each header in the Console widths[i] = headers[i].Length; // populates the array with the string sizes } // the return keyword instructs the program to send the variable // that follows back to the code that called this method return widths; } </code></pre> I would continue reading the chapter. More than likely the author fills in the implementation details of that method later on.

Guidance

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.
