Access fields of a Struct in an Object with Reflection

Question

I\'m trying to use reflection (ultimately on unknown at compile time) object which include struct. I\'ve got as far as TypedReference.MakeTypedRe

Answer 1

Frankly, there's no need whatsoever for TypedReference here - just a boxed struct should work fine:

    var amountField = obj.GetType().GetField("Amount");
    object money = amountField.GetValue(obj);
    var codeField = money.GetType().GetField("Code");
    codeField.SetValue(money, "XXX");
    amountField.SetValue(obj, money);

However! I will advise you of a few things:

• public fields instead of properties are not usually a good idea; that will often bite you later
• mutable structs (i.e. structs that can be changed after creation) are almost never a good idea, and will bite even more often, and bite harder
• combining mutable structs and public fields compounds it, but making it very problematic to change later
