Question

I’m trying to open a stream to a file.

First I need to save a file to my desktop and then open a stream to that file.

This code works well (from my previous project) but in this case, I don’t want to prompt the user to pick the save location or even the name of the file. Just save it and open the stream:

Stream myStream;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
    if ((myStream = saveFileDialog1.OpenFile()) != null)
    {
        PdfWriter.GetInstance(document, myStream);

Here’s my code for the newer project (the reason for this question):

namespace Tutomentor.Reporting
{
    public class StudentList
    {
        public void PrintStudentList(int gradeParaleloID)
        {
            StudentRepository repo = new StudentRepository();
            var students = repo.FindAllStudents()
                               .Where(s => s.IDGradeParalelo == gradeParaleloID);

            Document document = new Document(PageSize.LETTER);
            Stream stream;

            PdfWriter.GetInstance(document, stream);
            document.Open();
            foreach (var student in students)
            {
                Paragraph p = new Paragraph();
                p.Content = student.Name;
                document.Add(p);
            }

        }
    }
}

Use Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) to get the desktop directory.

string fileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory),
                               "MyFile.pdf");
using(var stream = File.OpenWrite(fileName))
{
    PdfWriter.GetInstance(document, stream);
}
