How to print a document using PrintDialog in C#

问题

Here is my Sample code . But its printing an Empty page

            printDocument1.DocumentName = "C:\a.pbf";// PrintDocument printDocument1
            printDialog1.Document = printDocument1;
            printDialog1.AllowPrintToFile = true;
            printDialog1.AllowSelection = true;
            printDialog1.AllowSomePages = true;
            printDialog1.PrintToFile = true;
            if (printDialog1.ShowDialog() == DialogResult.OK)
                printDocument1.Print();

Whats wrong with this?. Please help me

You need to handle the PrintPage event to actually provide the contents; MSDN has a full example. The DocumentName is purely something to show to the user - it is not the path of an existing file to magically print.

For printing an existing PDF, maybe look at this question
