    <p>I have a method like this:</p> <pre><code>private static double ComputePercentage(ushort level, ushort capacity) { double percentage; if(capacity == 1) percentage = 1; // do calculations... return percentage; } </code></pre> <p>Is it possible to make it of a generic type like "type T" where it can return either decimal or double, depending on the type of method expected (or the type put into the function?)</p> <p>I tried something like this and I couldn't get it to work, because I cannot assign a number like "1" to a generic type. I also tried using the "where T :" after <code>ushort capacity)</code> but I still couldn't figure it out. </p> <pre><code>private static T ComputePercentage&lt;T&gt;(ushort level, ushort capacity) { T percentage; if(capacity == 1) percentage = 1; // error here // do calculations... return percentage; } </code></pre> <p>Is this even possible? I wasn't sure, but I thought <a href="https://stackoverflow.com/questions/828807/what-is-the-base-class-for-c-numeric-value-types/828820#828820">this post</a> might suggest that what I'm trying to do is just plain impossible. </p> <hr> <p><strong>EDIT</strong></p> <p>Thanks to all who responded, many good answers. As <a href="https://stackoverflow.com/questions/2925441/how-to-create-a-generic-c-method-that-can-return-either-double-or-decimal/2925554#2925554">Tomas</a> pointed out, this is probably best done in two separate methods. As pointed out by both <a href="https://stackoverflow.com/questions/2925441/how-to-create-a-generic-c-method-that-can-return-either-double-or-decimal/2925470#2925470">TreDubZedd</a> and <a href="https://stackoverflow.com/questions/2925441/how-to-create-a-generic-c-method-that-can-return-either-double-or-decimal/2925592#2925592">TcKs</a>, the best way to get the functionality I would want is to use an implicit conversion that could return either a double or decimal implicitly. </p>

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.
