Reflection: Cast PropertyInfo to List<obj>

Question

As the title says, then I'm trying to cast a PropertyInfo to its "original" type, which is List<obj> in my case.

I've tried the code below without luck:

(List<obj>)pInfo.GetValue(pInfo, null)

(List<obj>)pInfo.GetValue(typeof<obj>, null)

It simply throws me an exception:

TargetException was unhandled: Object does not match target type.

I'm sure that I'm overlooking something extremely simple, but I cant figure out what.

Answer 1

The first parameter is the target object:

var list = (List<object>)prop.GetValue(obj,null);

Personally, though, I might be tempted to use the non-generic API here; generics and reflection rarely mix well:

var list = (IList)prop.GetValue(obj,null);

Answer 2

This:

(List<obj>)pInfo.GetValue(pInfo, null)

is wrong, the first argument to GetValue should be the object you're reading the property of, not the PropertyInfo itself.

Answer 3

You need to pass in the object you want to get the value for and not the type. Something like this.

List<obj> object ...

(List<obj>) pInfo.GetValue( object, null );
