使类属性成为可选的WebAPI MVC5

Question

I am using MVC5 WebAPI and i have a class as follows:

public string Name { get; set; }
public string Sub { get; set; }
public List<Actions> Actions { get; set; }

( Actions is another custom class)

When client makes an API call they have to send the Actions property as null. Is there a way that the client may not send the actions property at all?

How could this be done?

Thanks in advance.

Answer 1

I think this public List Actions { get; set; } is optional by default. if user/client don't specify it will be null. Have you added any required field validations to it?

Answer 2

If the client doesn't post actions. Then Actions at the time of model binding would be null . So there isn't any extra work from your side. In other words, if you post only Name and Sub , then Actions would be null.
