Cannot convert lambda expression to type 'object' because it is not a delegate type

Question

I have a base class that has a bool property which looks like this:

public abstract class MyBaseClass
{
     public bool InProgress { get; protected set; }
}         


        

Answer 1

Best would be to have the dictionary strongly typed, but if you assign the lambda to a specific lambda (delegate) first, it should work (because the compiler then knows the delegate format):

Action inp = InProgress => base.InProgress = InProgress;
dict.Add("InProgress", inp);

Or by casting it directly, same effect

dict.Add("InProgress", (Action)(InProgress => base.InProgress = InProgress));

Of course having such a dictionary format as object is discussable, since you'll have to know the delegate format to be able to use it.
