    <p>I currently have this type of code:</p> <pre><code>private void FillObject(Object MainObject, Foo Arg1, Bar Arg2) { if (MainObject is SomeClassType1) { SomeClassType1 HelpObject = (SomeClassType1)MainObject; HelpObject.Property1 = Arg1; HelpObject.Property2 = Arg2; } else if (MainObject is SomeClassType2) { SomeClassType2 HelpObject = (SomeClassType2)MainObject; HelpObject.Property1 = Arg1; HelpObject.Property2 = Arg2; } } </code></pre> <p>Assuming that SomeClassType1 and SomeClassType2 have the same set of properties that I want to assign (although they may differ in other ones), is it possible to dynamically cast MainObject to the appropriate type and then assign the value, without duplicating the code? This is what I would like to see in the end:</p> <pre><code>private void FillObject(Object MainObject, Foo Arg1, Bar Arg2) { Type DynamicType = null; if (MainObject is SomeClassType1) { DynamicType = typeof(SomeClassType1); } else if (MainObject is SomeClassType2) { DynamicType = typeof(SomeClassType2); } DynamicType HelpObject = (DynamicType)MainObject; HelpObject.Property1 = Arg1; HelpObject.Property2 = Arg2; } </code></pre> <p>And obviously C# complains about not being able to find DynamicType:</p> <blockquote> <p>The type or namespace name 'DynamicType' could not be found (are you missing a using directive or an assembly reference?)</p> </blockquote> <p>Is something like this possible in C# 2.0? If it's more messy than my current code, than I see no point in doing this, but I'm very interested to find out. Thanks!</p> <p>EDIT: Just to clarify, I perfectly understand that implementing an interface is the most appropriate and probably correct solution. That said, I'm more interested in seeing how to I could do it without implementing an interface. Thanks for great replies!</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.
