What is the bet way to determine if successive MonoObject * pointers refer to

Currently I use mono_object_hash(monoObject).
Is that the best approach?
My unmanaged code triggers and receives events.

Rather that wrestling with the embedded API on this it might be better
In my ObjC - Mono bridge I do something like:
MonoObject *monoObject = [self getMonoProperty:"FloatNullable”];
The question is what is the precise encoding required of the property
identifier?
A C# identifier is defined here :

What is the recommended way to create an instance of a nullable type, such as
System.Nullable?
I would prefer a method that used the embedded API as opposed to a C# helper
method.

Sorry. I was trying to imply that, as in mono_field_get_value_object, that

Is it the case that calling a static field via the embedded API does not cause
the static constructor to be run?
This seems to be the behaviour I am observing.
In the example below setting the static MetaDataXXX fields (before any other
static access) does not cause the static constructor to be

There is mono_class_inflate_generic_method() but this requires a
