Question

How does one obtain programmatically a reference to the object of which a FieldInfo object is a field?

For example, I’d like something like this:

myFieldInfo.GetOwner(); // returns the object of which myFieldObject is a field

Answer 1

Unfortunately you can’t because the relationship works the opposite way. A FieldInfo object represents metadata that is independent of any instance. There is 1 FieldInfo for every instance of an object’s field.

This is true in general about all Metadata objects such as Type, FieldInfo, MethodInfo, etc … It is possible to use the metadata objects to manipulate an instance of an object. For instance FieldInfo can be used to grab an instance value via the GetValue method.

FieldInfo fi = GetFieldInfo();
object o = GetTheObject();
object value = fi.GetValue(o);

But a metadata object won’t ever be associated with an instance of the type.
