    <p>I'm bone new to generics in C#, and I'm attempting to create a method that will use generics. I tripped across the where keyword when attempting to create a local variable, so I'm sure that it will be part of the solution.</p> <p>The reason for this is I have several different enum variables but the method would do the same to each (given a string that is one of the enum's defined values, toggle it on, using the enum like a bit field).</p> <p>I have most of this together, the part I'm now stuck at is being able to tell the generic method it's ok to allow "|=" as I'm certain any type passed in will support the operator.</p> <p>I would like to be able to maintain generality, if possible, so could either be an enum or a List and I would execute different code paths depending on the type.</p> <p>Example of what I'm taking about</p> <pre><code>enum someType { value1 = 1&lt;&lt;0, value2 = 1&lt;&lt;1, value3 = 1&lt;&lt;2 }; // and so on // some more enums private T someMethod&lt;T&gt;(string myIdentifyers) where T: new() { // suppose myIdentifiers is 1 more more of the valid enum options // assume that the correct strings and enum combinations will be passed T retval = new T(); while () { // assume a loop with a method call that parses off one identifyer at a time // if I have to convert the enum to an int first, so be it, but // at this point I can't tell it that a cast to int exists retval |= (T)System.Enum.Parse( typeof(T), oneIdentifyer, false ); } return retval; } </code></pre>

    1. COThe enum `someType` should be marked with the `[Flags]` attribute if your using it as a set of bitflags.

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.
