Directory.CreateDirectory not working.

Question

I want make a program to transfer files from iPhone to my pc.

I use Directory.CreateDirectory to create the directory.

But for the directory name end with "__", Directory.CreateDirectory not working.

No exception raised!, and the directory not created!

I have do some test.

Directory.CreateDirectory("E:\photos\202305\202305_"); => worked.

Directory.CreateDirectory("E:\photos\202305\202305__"); =>not worked!

Directory.CreateDirectory("E:\photos\202305\202305___"); => worked.

Directory.CreateDirectory("E:\photos\202305\202305__a"); => worked.

Why the Directory.CreateDirectory can not work for the directory end with double underscore ?

Hello there,

Could you check the Capabilities in your package.appxmanifest to see if there is <rescap:Capability Name="runFullTrust" /> under it ? When you package your WPF as a desktop bridge app, this capability need be added under the Capabilities . runFullTrust is a capabilities which allows apps to run at the full trust permission level on the user's machine.

Hope this resolves your Query !!
