NodeModuleLevelStruct[] is already IEnumerable<nodemodulelevelstruct>

Also, you should not use a struct in this case AFAICS.

I slightly disagree with Leppie on this one.

Take the Size struct as an example. It's not immutable, but a struct makes perfect sense and using it within your own struct would be good too.

NodeModuleLevelStruct temp;<br />
temp = theArray[42];<br />
temp.IsActive = true;<br />
theArray[42] = temp;

I can work on the copy, make any changes I like and then just forget the whole thing if I don't want/need to commit them. If it's a class, to have that flexibility you have to implement some sort of cloning method and work on the clone, then you still have to remember to reassign.

a large struct requires a loop to copy the memory area each time.

It's easier to use a struct for cloning instead of implementing proper cloning for a class, but you get worse performance.
