我做了一個批准或拒絕來自用戶註冊表的註冊請求的方法。批准/拒絕方法不工作在asp.net mvc
當用戶提交表單時，請求變爲掛起狀態，然後管理員有權拒絕或批准請求;但是我的方法無法正常工作，因爲沒有任何事情發生。
當我單擊拒絕或批准按鈕時，應用程序只刷新頁面。
任何人都可以告訴我我的代碼有什麼問題嗎？代碼片段如下。
這是批准控制器
public class ApprovedRegistrationController :BaseAdminController
{
// GET: Admin/ApproveRegistration
public ActionResult Index(string Status)
{ ViewBag.Status = (Status == null ? "P" : Status);
if (Status == null)
{ var register = objBs.registerBs.GetALL().Where(x => x.Approved == "P").ToList();
return View(register); }
else
{ var register = objBs.registerBs.GetALL().Where(x => x.Approved == Status).ToList();
return View(register); }}
public ActionResult Approve(int id)
{ try
{ var myRegistration = objBs.registerBs.GetByID(id);
myRegistration.Approved = "A";
objBs.registerBs.Update(myRegistration);
TempData["Msg"] = "Approved Successfully";
return RedirectToAction("Index"); }
catch (Exception e1)
{ TempData["Msg"] = "Approved Failed: " + e1.Message;
return RedirectToAction("Index");}}
public ActionResult Reject(int id)
{try
{ var myRegistration = objBs.registerBs.GetByID(id);
myRegistration.Approved = "R";
objBs.registerBs.Update(myRegistration);
TempData["Msg"] = "Rejected Successfully";
return RedirectToAction("Index");}
catch (Exception e1)
{ TempData["Msg"] = "Rejection Failed: " + e1.Message;
return RedirectToAction("Index");}}}

**Admin Base Contoller**
public class BaseAdminController : Controller
{
// GET: Admin/BaseAdmin
protected AdminBs objBs;
public BaseAdminController()
{
objBs = new AdminBs();
}
}
registerbs類是在批准控制器中使用
public class RegisterBs
{
private RegisterDb objDb;
public RegisterBs()
{
objDb = new RegisterDb();
}
public IEnumerable<Registration> GetALL()
{
return objDb.GetALL();
}
public Registration GetByID(int Id)
{
return objDb.GetByID(Id);
}
public void Insert(Registration registration)
{
objDb.Insert(registration);
}
public void Delete(int Id)
{
objDb.Delete(Id);
}
public void Update(Registration registration)
{
objDb.Update(registration);
}
}
<b>Registration db class<b>
public class RegisterDb
{
private XtechContext db;
public RegisterDb()
{
db= new XtechContext();
}
public IEnumerable<Registration> GetALL()
{
return db.Registrations.ToList();
}
public Registration GetByID(int Id)
{
return db.Registrations.Find(Id);
}
public void Insert(Registration registration)
{
db.Registrations.Add(registration);
Save();
}
public void Delete(int Id)
{
Registration registration = db.Registrations.Find(Id);
db.Registrations.Remove(registration);
Save();
}
public void Update(Registration registration)
{
db.Entry(registration).State = EntityState.Modified;
}
public void Save()
{
db.SaveChanges();
}
}
this is the interface pic then you easily understand it
不清楚你真正的問題是什麼，但是你有一個'Index（字符串狀態）'方法，當它們被重定向到時，你的'Approve（）'或'Reject 'Index（）'方法 –
你可以添加'RegisterDb.Update'的實現嗎？ – Guillaume
yes public void Update（Registration registration） db.Entry（registration）.State = EntityState.Modified; } – Mashhad
