Ok, but how can i inherit then from datarow?

Mex,

You are trying to call a constructor which is marked internal. Since
your code doesn't reside in the System.Data.dll assembly, the constructor
isn't available to you.

Redivivus,

Well, you would have to declare your constructor as internal, private,
or protected. Then, you can call the base constructor, passing along the
DataRowBuilder, if you have one available to you.

Oh, and I should note that the constructor is available to you, just in
calling it, you can't elevate the accessibility.

Consider this alternative. Create a strongly-typed dataset, add your tables
and then have a look at the "YourDataSet.Designer.cs" file. You'll see a
"DataRow" derivative for each table you created as well as a "DataTable"
derivative. Each class has some useful functions noting that the "DataRow"
derivatives in particular have a property wrapping each field (column) in
your tables (very clean to use in code). These are "partial" classes and you
can easily extend them with your own partial class.
