问题 In my API, I'd like to have routes like GET /api/v1/widgets/1,2,3 and GET /api/v1/widgets/best-widget,major-widget,bob-the-widget public class WidgetsController : MyApiController { public ActionResult Show(IEnumerable<int> ids) { } public ActionResult Show(IEnumerable<string> names) { } } I've got routes set up to get me to the action, but I can't figure out how to turn 1,2,3 into new List<int>(){1, 2, 3} and so on. Of course, I could just take a string and parse it in my action, but I'd like

问题 Is there a way in Entity Framework 4 (using CTP4 and Code First if that matters) to change the conventions used to automatically identify primary and foreign keys? I'm trying to use EF with a legacy database that uses a "pk/fk" prefix rather than an "id" suffix to mark keys. Also, it's not uncommon to have multiple foreign keys to an Address table, for example, called "fkAddressHome" and "fkAddressWork". I would prefer a method for changing this behavior in a systematic way so that I don't

问题 I'm trying to add a search box to a master page in an ASP.Net MVC web app. What's confusing me is how to properly implement it in the master page. So the user types in data into this search box, how should the data be handled from an MVC perspective?? I know I could use he master page's code behind, but I shouldn't. I'm currently trying to use a user control for this, but I'm not sure how to properly implement it and online resources seem to be limited. Would creating an HTML helper be best??

问题 So I was calling the Controller in MVC2 like this and I accessed the classic querystrings just fine. Please notice that the second parameter thing2 is URLEncoded already and again retrieving the URLEncoded querystring and URLDecoding is no problem. My example looks like this... http://mydomain.com/controller?thing1=1544&thing2=somethingURLEncoded Now I try to move to the MVC2 ASP.Net way of handling parameters and make myself a nice custom MapRoute. I test it to see that it works with a

问题 I have a custom Model, which contains another custom object (Objects1.Object2), I am correctly populating the object prior to display in the view and <%: Model.Object1.Name %> displays the data correctly yet <%: Html.TextBoxFor(model => model.Object1.Name) %> displays no data. I am new to MVC and would love to get around this issue as it is a stopping point to creating custom data model. Any info is greatly appreciated. 回答1: Are you trying to modify this in a POST action? If you are then note

问题 I need to add class attribute to the body tag from a view file (.aspx), but the tag is in the master file. How can I access the body tag from a view? 回答1: In your view output you could just add a jQuery client script to do it which will run once your page is pieced together: $('body').addClass('yourClass'); Another method would be to store the class data in your controller like: ViewData["MasterPageBodyClass"] = "yourClass"; Then in your MasterPage view you could check for the existance of

问题 I'm using a generated class as a model, and I wish to add DataAnnotation attributes to some of its properties. As it's a generated code, I don't want to add the annotations directly. Is there another way to attach them to a property? I'd considered making the model an interface, and using a partial class to get the generated class to subscribe to it. Is there a less elaborate solution, assuming that would even work? 回答1: Yes there is. You have to create metadata class that will have the same
