Question

TableAdapter is a wrapper for DataAdapter. It’s impossible to use TableAdapters in generic way (bacause they inherit Component class). Is it possible to get the wrapped DataAdapter out of TableAdapter?

Answer 1

As Brian pointed out, a table adapter is a partial class. If you want to expose the DataAdapter you can achieve that by the following code. (assuming you have a TableAdapter class MyTableAdapter.

public partial class MyTableAdapter
{
    public DbDataAdapter Adapter
    {
        get { return this._adapter; }
    }
}

Alternatively, you could write some general purpose method (or extension method) that returns the private adapter using reflection. That way you wouldn’t have to “touch” every table adapter you create.
