What is the difference between this code
And this code
Almost nothing, just a little FileAccess.Read !
But this little thing makes a big difference when you run your software in a secured environment.
The application with this piece of code was deployed to a customer reporting that the application was crashing at a the point of reading the settings. Weird, really weird. After getting back the log and I finally discovered that using juste FileMode.Open needs modify rights and that’s was the issue because the customer deploy the settings file on a folder in which the user doesn’t have the modify rights.
