Hallo, being completely new in ASP.Net I do not know how to pass the data from a simple SELECT into the Attributes of an Object. The Class has similar attributes to those of the DB-Table. Is there already a standard (Microsoft's ?) procedure for such a process?

Thanks in advance.

There are several.

Here's a good starting point:

What you're talking about, specifically, would be the responsibility of the business logic layer in standard application models.
