    <p>I have the following class sample:</p> <pre><code>public class ExceptionOne : BaseException { //Define the error bit the exception represents public static int ErrorBitNumber = 1234; public ExceptionOne() { //Do something in the ctor } } </code></pre> <p>(<em>There is no relevant functionality in <code>BaseException</code> so its not necessary to show the code ;)</em> )</p> <p>Further there are other exception classes with the property called <code>ErrorBitNumber</code> but with other values for the property <code>ErrorBitNumber</code>. Each exception class represents an errorbitnumber - so there is always one class for one errorbitnumber.</p> <p>As i never know which errorbitnumber i receive (<em>if i receive one</em>) i want to implement the following --></p> <ul> <li>Go thru each existing class which derives from <code>BaseException</code> and look for the received error bit number</li> <li>If class is found, create an instance of the specific class (<em>fill some further properties or something</em>)</li> <li>Throw it</li> </ul> <p>I know that this should be possible to implement by using reflection - but truly i don't know how. Further i think using the <code>ErrorBitNumber</code> as <code>public static</code> should be the right approach. If not, feel free to correct me.</p> <p><strong>Update 1:</strong></p> <p>For understanding: We have header files which will be parsed. In this header files there are errors defined. For each error a exception class with the specific errorbitnumber will be created. So on the lowest tier in the architecture i receive an error bit number and have to throw the specific exception which represents the specific errorbitnumber</p>

    1. CODon't look for a reflection hack for this. The proper pattern to use here is the Factory pattern. Simple and clean.

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.
