问题描述

我在Mvc4工作,我想将页面重定向到选定的下拉值,我在下面使用通过视图模型的下拉菜单

public ActionResult Create()

{

var Complain = new ComplainViewModel()

{

Countries = new SelectList(db.Countries,Id,Name ,0),

EffectedStates = new SelectList(db.States,Id,Name,null),

EffectedCities = new SelectList(db.Cities, Id,Name,null),

EffectedAreas = new SelectList(db.EffectedArea,Id,Name,null),

Types = new SelectList (db.Type,Id,Name,0),

};



返回查看(投诉);

}



//

// POST:/ ComplainView / Create



[AllowAnonymous]

[HttpPost]

public ActionResult Create(ComplainViewModel抱怨)

{

试试

{



complain.Comp.country = db.Countries.Find(complain.CountryId);

complain.Comp.State = db.States.Find(complain.States);

complain.Comp.City = db.Cities.Find(complain.Cities);

complain.Comp.Area = db.EffectedArea.Find(complain.Areas);

complain.Comp.ComplainType = db.Type.Find(complain.TypeId);



投诉CV = db.Complains.Add(抱怨.Comp);

db.SaveChanges();
