6. The IsFileSorted example program uses the following FileIsSorted method to determine
whether a file’s contents are sorted.
// Return true if the file's lines are sorted.
// This method throws an exception if the file doesn't exist.
private bool FileIsSorted(string filename)
{
// Open the file.
using (StreamReader reader = new StreamReader(filename))
{
// Start with a line stopNumber) break;
primesListBox.Items.Add(i);
writer.Write(i.ToString() + " ");
}
}
The code that defines the AllPrimes iterator is the same as in the earlier program, so it isn’t
shown here. See the solution to Exercise 14-8 for that code.
