c# - mvc3 RedirectToAction

Question

为什么这不起作用。当我在我的 Create 方法中重定向时，它一直告诉我编辑需要一个 EditStudyModel。重定向应该执行 get，对吗？

    public ViewResult Create()
    {
        var createStudyModel = new CreateStudyModel();
        return View(createStudyModel);
    }

    [HttpPost]
    public ActionResult Create(CreateStudyModel createStudyModel)
    {
        try
        {
            //TODO: Send CreateStudyCommand
            return RedirectToAction("Edit", new { scientificStudyId = new Guid("{1C965285-788A-4B67-9894-3D0D46949F11}") });
        }
        catch
        {
            return View(createStudyModel);
        }
    }

    [GET("ScientificStudy/Create/{scientificStudyId}")]
    public ActionResult Edit(Guid scientificStudyId)
    {
        //TODO: Query real model
        var model = new EditStudyModel() {StudyNr = "T01", StudyName = "Test"};
        return View(model);
    }

    [HttpPost]
    public ActionResult Edit(EditStudyModel editStudyModel)
    {
        try
        {
            //TODO: Send UpdateStudyCommand
            return RedirectToAction(""); //TODO: Terug naar Studie lijst
        }
        catch
        {
            return View(editStudyModel);
        }
    }

Answer 1

您正在返回一个带有 URL 作为字符串的重定向， Controller 无法解析 GUID 并将其转换回 guid 对象，因此它无法解析要使用的正确方法签名。将其更改为:

return RedirectToAction("Edit", new { scientificStudyId = "{1C965285-788A-4B67-9894-3D0D46949F11}" });

和

public ActionResult Edit(string scientificStudyId)
