foreach(DataColumn myCol in myDataTable.Columns)

Console.Write(myRow[myCol]+"\t");
}
Console.WriteLine();

}
finally

Public Sub UseDataTable(ByVal myDataTable As DbDataTable, ByVal myCommand As DbCommand, ByVal myConnection As DbConnection)
myDataTable.Connection = myConnection
myCommand.CommandText = "SELECT * FROM Test.Dept"
myDataTable.SelectCommand = myCommand
