Does TableAdaper.Fill() call Connection.Close() internally?

=?iso-8859-1?B?0A==?=

The Microsoft online help is full of TableAdapter examples like

customersTableAdapter1.Fill(northwindDataSet1.Customers);

I would expect the next line to be something like

customersTableAdapter1.Connection.Close();

But I haven't seen that in the code samples, and VS doesn't generate it.
 
Fill automatically opens and closes the Connection.

The tableadapter closes a connection if it has self opened that.

The tableadapter opens a connection it that is not already open.
