Web API2中返回错误

Question

I need to return error from my Web API. That means after validation. I have custom error model will send as a json. How can I send this? Like BadRequest(Model); IHTTPActionResult is using. If using HttpresponseMessage, We can pass. But in IHTTPActionResult how Can I pass custom error model with BadRequest.

Answer 1

Just return an internal server error. It has an overload to return an exception with a message.

public IHttpActionResult YourMethod()
{
    try
    {

    }
    catch
    {
        return InternalServerError();
        //or
        return this.BadRequest(JsonConvert.SerializeObject(yourModel));
    }
}
