using (var context = new BirdHousesEntities()) // Line A.
{
var birdHouses = context.SortBirdHousesByName(); // Line B.
foreach (SortBirdHousesByName_Result bh in birdHouses) // Line C.
{
birdHouseListBox.Items.Add(bh.ID.ToString("000") + " " +
bh.BirdHouseName + " " + bh.Price.ToString("C"));
}

}
}
catch (Exception ex)
{
statusLabel.Text = "Display sort by name error: " + ex.Message + " " +
ex.GetType().ToString();
}
}
Explain line A.
Explain line B.
Explain the foreach loop that begins on line C.
Line A: here we are creating the object for the
BirdHousesEntities()
Line B: sorting the names by name
Line C: as we sorted and stored in birdHouses so we are
iterating
through each object and adding the name and price to the items
list

Please provide the full code...the skeleton is down below: Note: Each file must contain an int at the beginning, stating the number of records in the file. Afterwards, the number of records in the file will follow. Each record that follows will consist of a last name (String), and a gpa (double). However, to test the error handling of your program, the number of records will not always match the int value. All possible combinations should be tested. 1.) Prompt...
