Windsor Castle - Null constructor argument

Question

How to pass null constuctor argument using Castle Windsor? I thought the following would work

<parameters> <repository>null</repository> <message>null</message> </parameters>` 

Answer 1

If you want them to be empty, that means they are non-essential dependencies. Having them as arguments to ctor, you suggest something else. You must redesign your class to have a different constructor that accepts only significant dependencies if you want them not to change throughout the entire life cycle of an object (read-only) or display them as properties.

In Windsor, you cannot force it to skip zeros for the reasons stated in another answer.

Answer 2

Wouldn't it be better just to have an additional public constructor that does not accept these parameters, then you will not need to register the parameters in the config?

Answer 3

This was discussed some time ago in the list of letters, and at that time I was looking at the code. Zero values ​​are intentionally filtered out (mainly due to the resolution of the complicating type type).

I could not find an easy way to make a special case to add them.
