我想在RedirectToAction中传递对象.这是我的代码:
RouteValueDictionary dict = new RouteValueDictionary();
dict.Add("searchJob", searchJob);
return RedirectToAction("SearchJob", "SearchJob", dict);
其中searchJob是SearchJob的实例.但我没有得到SearchJob动作方法的数据.相反,我得到searchJob = Entity.SearchJob的查询字符串.请帮我.我究竟做错了什么？
我想重定向到其他Controller中的一个动作,但它在这里不起作用我的ProductManagerController中的代码:
[HttpPost]
public ActionResult RedirectToImages(int id)
{
return RedirectToAction("Index","ProductImageManeger", new { id=id });
}
这在我的ProductImageManagerController中:
[HttpGet]
public ViewResult Index(int id)
{
return View("Index",_db.ProductImages.Where(rs=>rs.ProductId == id).ToList());
}
它没有参数很好地重定向到ProductImageManager/Index(没有错误)但是使用上面的代码我得到这个:
参数字典包含"... Controllers.ProductImageManagerController"中方法"System.Web.Mvc.ViewResult Index(Int32)"的非可空类型"System.Int32"的参数"ID"的空条目.可选参数必须是引用类型,可空类型,或者声明为可选参数.参数名称:参数
我想使用redirectToAction()方法传递多个对象.下面是我要重定向到的动作结果.
public ActionResult GetEmployees(Models.Department department, Models.Category category, Models.Role role)
{
return View();
}
我想做类似下面的事情
public ActionResult test()
{
Models.Department dep = new Models.Department();
Models.Category cat.......etc
return RedirectToAction("GetEmployees", dep, cat, role); }
任何帮助将不胜感激 - 谢谢
更新
我可以使用类似的东西吗？
Models.Department dep = new Models.Department() { DepId = employee.DepartmentId };
Models.Category cat = new Models.Category() { CatId = employee.JobCategoryId };
Models.Role title = new Models.Role() { RoleId = employee.JobTitleId };
return RedirectToAction("GetEmployees", new { department = dep, category = cat, role = title });
There are two page one is Edit page and the other is Main Detail page which is combined data of some entities In edit page : after edit done and I posted the data to API as below
public async Task<IActionResult> OnPostAsync(Guid id)
{
ManufacturerAuthorizedPerson.Id = id;
ManufacturerAuthorizedPerson.ManufacturerId = GetManufacturerId(id);
if (!ModelState.IsValid)
{
await OnGetAsync(id);
return Page();
}
HttpResponseMessage = await httpSystemApi.PutAsync("ManufacturerAuthorizedPersons", ManufacturerAuthorizedPerson);
if (HttpResponseMessage.IsSuccessStatusCode)
{
return RedirectToPage("../Detail", ManufacturerAuthorizedPerson.ManufacturerId);
}
else
{
await OnGetAsync(id);
return Page();
}
}
The ID …
调试我的MVC程序时遇到问题,我想访问名为"UserActivity"的数据库.在浏览器上,它说"localhost页面不起作用
localhost重定向了你太多次了."
但没有显示具体的错误位置.
这是我的UserActivtyController,GET/UserActivity/Index代码:
public class UserActivityController : BaseController
{
//GET /UserActivity/Index
public ActionResult Index(string returnUrl, int page = 1, string sort = "Id", string sortDir = "ASC", string filter = null)
{
String query = @"
SELECT Id
,CreatedBy
,CreatedOn
,ModifiedBy
,ModifiedOn
,ContactId
,EntityName
,EntityId
,ActivityType
,ActivityStatus
,DueDate
,ActualEndDate
,MasqueradeOn
,MasqueradeBy
FROM UserActivity
-- ORDER BY CreatedOn DESC
-- OFFSET (@PageNumber -1) * 30 ROWS
-- FETCH NEXT 30 ROWS ONLY
";
//string countQuery = @""
List<UserActivityModels> userActivity = …我在控制器中有一个名为"Registration"的动作方法
public ActionResult Facility(int id = 0, int contractId = 0)
当我从url调用这个方法时
/Registration/Facility/0?contractId=0
它工作正常.现在,当我尝试在另一种方法中构建上面的url时
return RedirectToAction("Facility/0?contractId="+ model.ContractId);
它不起作用,浏览器中的网址构造不好就像它
/Registration/Facility/0%3fcontractId%3d0
任何人都可以告诉我,我在这里做错了什么？
我想知道是否有一种优雅的方法可以将一组复杂类型添加到RouteValueDictionary或兼容类型？
例如,如果我有一个类和一个动作:
public class TestObject
{
public string Name { get; set; }
public int Count { get; set; }
public TestObject()
{
}
public TestObject(string name, int count)
{
this.Name = name;
this.Count = count;
}
}
public ActionResult Test(ICollection<TestObjects> t)
{
return View();
}
然后我知道如果我通过URL"/Test?t[0].Name=One&t[0].Count=1&t[1].Name=Two&t[1].Count=2"调用此动作,MVC将映射那些查询字符串参数自动返回ICollection类型.但是,如果我使用Url.Action()在某处手动创建链接,并且我想传递参数的RouteValueDictionary,当我向RouteValueDictionary添加ICollection时,Url.Action只是将其呈现为类型,如&t = System.Collections.Generic.List.
例如:
RouteValueDictionary routeValDict = new RouteValueDictionary();
List<TestObject> testObjects = new List<TestObject>();
testObjects.Add(new TestObject("One", 1));
testObjects.Add(new TestObject("Two", 2));
routeValDict.Add("t", testObjects);
// Does not properly create the parameters for the List<TestObject> collection.
string …我知道你可以从一个动作重定向到另一个动作,如:
public ActionResult Index() {
return View();
}
public ActionResult OtherAction(){
return RedirectToAction("Index");
}
好.我没有找到我的问题的解决方案:如何重定向到具有参数的操作？例如:
public ActionResult Index(string v1, int i1) {
return View();
}
public ActionResult OtherAction(string value, int size){
return RedirectToAction("Index", // here need some adjustements or another trick);
}
对不起,但我没有在这里找到任何相关的问题,也许我不知道使用搜索:)
