I tried hours but I could not make it out so I want to ask you about using Invoke method to add element to Arraylist.
As you can see in below, I configured ArrayList(and List, I used to tried) as TargetObject of Invoke method, but error happens with message like this.
Main has thrown an exception
Source: Invoke method
Message: Value cannot be null.
Parameter name: TargetObject
I looked for “invoke method” in offical activity guide so I cannnot find out how can I use.
Could you tell me how to add element into arraylist or list ?(If the way using invoke method, it could be good)
