ASP.Net 4.5 WebForms返回重定向到URL(ASP.Net 4.5 WebForms Return Redirect to URL)

ASP.Net 4.5 WebForms返回重定向到URL(ASP.Net 4.5 WebForms Return Redirect to URL)

有没有办法像在MVC中一样将重定向返回到WebForms中的URL。 我有一个简单的函数，如果列表为空则返回null，如果列表中有项目则返回列表。 如果列表为空，我希望能够重定向到同一网站中的另一个页面。

这是功能

BillContext _context = new BillContext(); public List<Models.Bill> GetBills() { var bills = from b in _context.Bills where b.UserName == HttpContext.Current.User.Identity.Name select b; if (bills.ToList().Count() < 1) { return null; } else { return bills.ToList(); } }

而不是返回null，我想返回这样的东西

return Response.Redirect("~bills/create

但这不起作用，它给了我一条不会消失的红色线条。 这是VS2012 ASP.net WebForms项目

Is there a way to return a redirect to URL in WebForms the same way you can in MVC. I have a simple function that returns a null if the list is empty and returns the list if there are items in the list. I want to be able to redirect to another page in the same website if the list is null.

Here is the function

BillContext _context = new BillContext(); public List<Models.Bill> GetBills() { var bills = from b in _context.Bills where b.UserName == HttpContext.Current.User.Identity.Name select b; if (bills.ToList().Count() < 1) { return null; } else { return bills.ToList(); } }

Instead of returning null, I want to return something like this

return Response.Redirect("~bills/create

But this is not working, it is giving me a red squigly line that will not go away. This is VS2012 ASP.net WebForms Project

最满意答案

您可以重定向到这样的另一个aspx页面

Response.Redirect("mypage.aspx");

您需要提供最终扩展名为.aspx的页面名称，而不像MVC中那样需要提供URL。

编辑：

public List<Models.Bill> GetBills() { var bills = from b in _context.Bills where b.UserName == HttpContext.Current.User.Identity.Name select b; if (bills.ToList().Count() < 1) { HttpContext.Current.Response.Redirect("mypage.aspx"); return null; } else { return bills.ToList(); } }

You can redirect to another aspx page like this

Response.Redirect("mypage.aspx");

you need to provide your page name with .aspx extension in end unlike that in MVC where you needed to provide the URL.

Edited :

public List<Models.Bill> GetBills() { var bills = from b in _context.Bills where b.UserName == HttpContext.Current.User.Identity.Name select b; if (bills.ToList().Count() < 1) { HttpContext.Current.Response.Redirect("mypage.aspx"); return null; } else { return bills.ToList(); } }
