How to disable the properties of pdf files using C#.. Here i want to disable print, save properties of pdf file

If you want to disable print, you need to set permission for your PDF document.

I don't have a direct solution, but the following code I use can meet your requirement. 

  doc.Security.Permissions = PdfPermissionsFlags.EditContent;

Through using the above code, besides editing, all the other functions, print, copy etc. will be disabled. 

(The above code is based on a .NET PDF component)

The following image shows properties of my PDF.
