Create Custom Json Error in Asp.NET MVC

Question

I am using a JavaScript plug-in and if there is an error it expects format like;

{error: 'You are not allowed to upload such a file.'}

In my MVC Web API I am throwing error like;

 var error = string.Format("An error has been occured. Please try again later.");
                throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.InternalServerError, error));

and it is represented in HTTP response like below;

{"Message":"An error has been occured. Please try again later."}

how can I achieve to return in first way?

Answer 1

You can create an anonymous object

throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.InternalServerError,new { error = "your error message here!"}));
