It’s not legal to have a struct that contains itself as a member. This is because a struct has fixed size, and it must be at least as large as the sum of the sizes of each of its members. Your type would have to have 8 bytes for the two floats, at least one byte to show whether or not info
is null, plus the size of another info
. This gives the following inequality:
size of info >= 4 + 4 + 1 + size of info
This is obviously impossible as it would require your type to be infinitely large.
You have to use a reference type (i.e. class). You can make your class immutable and override Equals
and GetHashCode
to give value-like behaviour, similar to the String
class.
