Question

I am trying to use a set of conditional statements that will set up an enumeration attributed with [Flags]. However, the compiler complains that ‘m’ is unassigned. How can I rewrite the following to achieve my intended functionality?

Media m; if (filterOptions.ShowAudioFiles)     m = m | Media.Audio; if (filterOptions.ShowDocumentFiles)     m = m | Media.Document; if (filterOptions.ShowImageFiles)     m = m | Media.Image; if (filterOptions.ShowVideoFiles)     m = m | Media.Video; 

Answer 1

You need to initialize m. Create a ‘None’ flag that has value 0 then:

Media m = Media.None; 

Then the rest of your code.
