我将返回DTO包裹在Htt的presponseMessage如下：

 返回this.Request.CreateResponse（的HTTPStatus code.OK，分支机构）;
 

DTO /视图模型将使只发送所需的属性。

Htt的presponseMessage允许发送附加状态code，例如在输入无效的情况下，我们可以发送状态code precondition失败。

 如果（model.EventDate == NULL）
            {
                VAR responseMessage =新的Htt presponseMessage（）;
                responseMessage.Status code =的HTTPStatus code preconditionFailed。
                responseMessage.ReasonPhrase =请输入有效的EVENTDATE输入;
                返回responseMessage;            }
 

I'm working on a webapi, EF5, Windsor Castle in a MVC 4 project, and I have a question...should I return the Entity (or DTO) in the Get method or Should I return an HttpResponseMessage? What's the better way and more standard way to do it?

So, Is it this?

[System.Web.Http.HttpGet]
public HttpResponseMessage GetById(long id)
{
    var branch = Uow.Branches.GetById(id);
    if (branch != null)
    {
        Request.CreateResponse(HttpStatusCode.OK, branch);
    }

    throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound));
}

Or this?

[System.Web.Http.HttpGet]
public Branch GetById(long id)
{
    var branch = Uow.Branches.GetById(id);
    if (branch != null) return branch ;
    throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound));
}

I will return DTO wrapped in HttpResponseMessage as below:

return this.Request.CreateResponse(HttpStatusCode.OK, branch);

DTO/ViewModel will enable to send only required properties.

HttpResponseMessage allow to send additional status code, for example in case of invalid input, we can send statusCode precondition failed.

if (model.EventDate == null)
            {
                var responseMessage = new HttpResponseMessage();
                responseMessage.StatusCode = HttpStatusCode.PreconditionFailed;
                responseMessage.ReasonPhrase = "Please enter valid EventDate input";
                return responseMessage;

            }
