Save File as PDF Example (C#)

//--------------------------------------------------------------------------
// Preconditions:
// 1. Specified drawing document to open exists.
// 2. The folder (c:\test) to which to save
//    the PDF file exists. If it does not exist,
//    create it or change the path to one that
//    exists on your system.
//
// Postconditions:
// 1. Specified drawing document is opened.
// 2. All but the last drawing sheet are saved to an array.
// 3. The array of drawing sheets are saved to a PDF
//    file called foodprocessor.pdf.
// 4. foodprocessor.pdf opens.
