Question

Short question: How can I modify individual items in a List? (or more precisely, members of a struct stored in a List?)

The problem you are having in your foreach is that structs are value types, and as a result, the loop iteration variable isn't actually a reference to the struct in the list, but rather a copy of the struct.

My guess would be the compiler is forbidding you change it because it most likely would not do what you expect it to anyway.

subItems.Clear() is less of a problem, because altho the field may be a copy of the element in the list, it is also a reference to the list (shallow copy).

The simplest solution would probably be to change from a struct to a class for this. Or use a completely different approach with a for (int ix = 0; ix < ...; ix++), etc.
