通过Process写入文件夹-ASP.NET和Windows Server 2008 R2

Question

I generate PDF files from HTML page through wkhtmltopdf (using Process from C#).

On local system (Windows 7) it's works, but on Windows Server 2008 R2 I have "System.IO.FileNotFoundException". wkhtmltopdf executed by Process (C#) not have enough permission to write file.

I tested a lot of folders (in example: "APPDIR/Content/temp"), but I have no idea what should I do.

Answer 1

The process your application runs as, has to have sufficient permissions to write to a folder.

Your (most likely judging by ASP.NET tag) website can be configured to run as any user you want in IIS management console.

By default the application pool runs as ApplicationPoolIdentity and to grant access permissions to it you would use: IIS AppPool\\ApplicationPoolName account.

You can also change the application pool to run as another account and configure folder permissions for that account instead.

You will have to type the full account name in the box as search is an Active Directory feature and doesn't work as expected for local accounts (In Select Users or Groups dialog)
