An article on getting field offset of struct or class object, and how to make it cross-runtime, so it works in Unity (Mono/IL2CPP) and real dotnets.

Field offsets are good stuff to read/write fields without incurring into reflection, so we can avoid TypedReferences (not supported in IL2CPP) and also we avoid GC allocations for fieldInfo.SetValue(object target, object value), if both target and value are structs that's two boxing operations!

Let's dive in!

.NET(s) Fields and their offsets

Field offsets can help you in numerous ways, first what comes in mind is that you can set fields of the struct or class instance without using TypedReference (doesn't work in IL2CPP) and without GC allocs which comes with boxing when either instance or a…
