Steps to creating single PDF files from a Multipage PDF File

1. Import the trial Developer License:
   
   
   License.Import(new StreamReader(@"C:\Users\Joe\license.xml"));
   
   
2. Allow multi selection of only PDF files using OpenFileDialog:
   
   
   // Create a Open File Dialog that allows you to select multiple files
   OpenFileDialog OpFile = new OpenFileDialog();
   OpFile.Multiselect = true;
   
   //show only PDF Files
   OpFile.Filter = "PDF Files (*.pdf)|*.pdf";
   
   //Do nothing if someone clicks on cancel
   if (OpFile.ShowDialog() != System.Windows.Forms.DialogResult.OK)
   {
   ...
   
   
3. Use PagesModel to split the file:
   
   
   //Create a new PagesModel object and open the selected file.
   PagesModel model = new PagesModel();
   model.OpenPDF(OpFile.FileName);
   
   
4. Create a loop with a defined int called pageIndex set to zero to count the pages:
   
   
   
   //Define a string called partsFolder to get the directory information for the selected file
   String partsFolder = Path.GetDirectoryName(OpFile.FileName);
   partsFolder = Path.Combine(partsFolder, Path.GetFileNameWithoutExtension(OpFile.FileName));
   Directory.CreateDirectory(partsFolder);
   
   if (model.Count > 1) //If the PDF has more than one page then count the pages
   {
       for (int pagelndex = 0;
       pagelndex < model.Count;
       pagelndex++ // same as saying “pagelndex = pagelndex + 1”
       )
   }
   ...
   
   }
   
   
5. Clear model of any selection and add the new pageIndex:
   
   
   model.Selection.Clear();
   model.Selection.Add(pagelndex);
   ...
   
   
6. Manage if there is only one page in the selected file:
   
   
   
   //Name the extracted pages to the source file name plus the page number it relates to using pageIndex
   String path = Path.Combine(partsFolder, Path.GetFileName(OpFile.FileName));
   path = Path.ChangeExtension(path, "." + (pageIndex + 1).ToString() + ".pdf");
   
   ...
   
   
7. Save and extract the pages:
   
   
   model.Save(path, true);
   ...
   
   
8. Just save a copy if the selected file only has one page:
   
   
   else // If there is only one page in the selected PDF File
   {
      String path = Path.Combine(partsFolder, Path.GetFileName(OpFile.FileName));
   
      path = Path.ChangeExtension(path, ".1.pdf");
   
      File.Copy(OpFile.FileName, path, true);
   
      File.SetAttributes(path, FileAttributes.Normal); // make sure the copy is not readonly
   }
   
   
9. Close Model:
   
   
   model.Close();
   ...
