this is kind of tough. Currently we do have the limitation that we cannot add an edge flange to a curved edge. Therefore I was using a swept flange in order to be able to unfold a curved base flange with an edge flange attached:
The warning message at the swept flange feature tells me that SOLIDWORKS cannot use the assigned k-factor and that the sketched path is used instead. So nothing to worry about. You could still use an extruded base flange in order to get the developed length that has to be applied to the path in order to get the correct developed length for the swept flange.
In the next step I removed some material and patterned the cut:
Added the slot holes on top of the remaining flanges (to be honest I did not check the correct angle for the pattern so it might be off) and the cuts close to the remaining flanges:
Now you should be able to unfold the sheet metal body:
Hope this helps.

Yes， of course
Can you attach your *.sldprt file here?
What version of SolidWorks are you using?
The slots in the flat pattern are not correct, radius is not the same top and bottom of slot. How would you correct that?
the slots in the flat pattern take the deformation of the flange into account. In theory the flange gets compressed in order to match the folded state. In order to have the slots compressed to the right size the slots would have to be bigger in order to match the desired size in the bent state.
In the flat pattern the flange is rectangular (at least visually and I have not verified if it really is):
In the folded state the flange the length of the flange gets compressed:
And the compression gets also applied to the slot, respectively the slots gets bigger in the flat pattern.
I guess the only thing you can do is to alter the flat pattern manually in order to apply the desired size of the slots.
