✅ Getting array values through Reflection
I'm making an "interpreter" using reflection but I don't know how to access the value of array elements. I've tried with IEnumerators this way:
But I get this error:
On the line I retrieve the value.
(also any other way of making an interpreter in unity that you can think of, please tell)
C++
//at this point splitFunction[index] should be something like "arrayName[2]"
//nestedValue is the object that contains the array
string[] splitEnumerator = splitFunction[index].Split('[');
FieldInfo field = nestedValue.GetType().GetField(splitEnumerator[0]);
int enumIndex = int.Parse(splitEnumerator[1].Replace("]", ""));
IEnumerator theEnum = ((IEnumerable)field.GetValue(nestedValue)).GetEnumerator();
theEnum.Reset();
for(int m = 0; m < enumIndex; m++)
{
theEnum.MoveNext();
}
nestedValue = theEnum.Current;
