Can I assign a null value to an anonymous type property? [duplicate]

Question

I have the following in WebAPI that is converted to a JSON string and sent to the client:

return Ok(new     {         Answer = "xxx",         Text = question.Text,         Answers = question.Answers.Select((a, i) => new         {             AnswerId = a.AnswerId,             AnswerUId = i + 1,             Text = a.Text         })     }); 

Now I realize that I would like to assign the value null to Answer. However this gives me a message saying

cannot assign <null> to anonymous type property.  

Is there a way I can do this without having to define a class just so I can assign the null?

Answer 1

Absolutely - you just need to cast the null value to the right type so that the compiler knows which type you want for that property. For example:

return Ok(new {     Answer = (string) null,     Text = ...,     ... });
