PDFsharp & MigraDoc Forum

Hi People,

I am attempting to use PDFsharp to merge a bunch of PDF files on a sharepoint site. At this point i am not meging files from the doclib but simply a folder within the iis site. I can read and write new pdf docs, but when it comes to merge them i have an issue. I am not using PDF sharp to write the new pdf docs but ExpertPDF as i am creating HtmlToPdf documents

The trust level on the sharepoint site has a custom policy, is there anything i need to add to the policy for the pdf sharp libary? i have attached the policyfile as a txt file if anyone want to view it.

the error i am recieveing is as follows, can anyone point me in the right direction?

Hi!

No file attached.

I googled a little bit.
Maybe the ReflectionPermission is missing.

The article I found:

Hi,

Thanks for your help.

i added the ReflectionPermission to the config file and it worked? thanks for pinpointing that peice of information, much appreciated.

As i am doing this on a dev server as a proof of concept, i am going to be asked what the ReflectionPermission is used for when moving to the UAT site
And why is it needed. What does the component use it for? Can you help with any sort of answer?

<SecurityClass Name="ReflectionPermission" Description="System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

<IPermission class="ReflectionPermission" version="1" Unrestricted="true" />

PDFsharp was originally implemented with .NET 1.1.

This routine

uses reflection to find the constructor for Type type (this technique is also used in other classes).

Generics were not available yet.
Nowadays it would rather be like this:
