ASP.NET MVC DropDownList SelectedValue转换为ViewBag？

Question

I have this drop down list:

@{ var listItems = new List<MVC_WebUI.Models.SelectedListItems> 
                { new MVC_WebUI.Models.SelectedListItems { Text = "---Select---", Value = "0" }, 
                       new MVC_WebUI.Models.SelectedListItems { Text = "Answer 1", Value = "1" }, 
                       new MVC_WebUI.Models.SelectedListItems { Text = "Answer 2", Value = "2" }, 
                       new MVC_WebUI.Models.SelectedListItems { Text = "Answer 3", Value = "3" }, 
                        new MVC_WebUI.Models.SelectedListItems { Text = "Answer 4", Value = "4" }                        
                       }; 
                     }
@Html.DropDownList("Answer", new SelectList(listItems, "Value", "Text"), new { onchange = "getAlldata()" }) 

Can you please explain, how to get the selected value into a Viewbag variable? Thank You!!

Why u need it in view bag Just try like below

Note : In below i have mention ControllerName that must the Name of your controller.

@using (Html.BeginForm("MethodName", "ControllerName", FormMethod.Post))
{
    @{ var listItems = new List<MVC_WebUI.Models.SelectedListItems> { 
                   new MVC_WebUI.Models.SelectedListItems { Text = "---Select---", Value = "0" }, 
                   new MVC_WebUI.Models.SelectedListItems { Text = "Answer 1", Value = "1" }, 
                   new MVC_WebUI.Models.SelectedListItems { Text = "Answer 2", Value = "2" }, 
                   new MVC_WebUI.Models.SelectedListItems { Text = "Answer 3", Value = "3" }, 
                   new MVC_WebUI.Models.SelectedListItems { Text = "Answer 4", Value = "4" }                        
            }; 
      }

 @Html.DropDownList("Answer", new SelectList(listItems, "Value", "Text"), new { onchange = "getAlldata()" }) 
        <input type="submit" value="Click" />

}

And your Action method bust be like below.

Then you can able to get it in the below method.

[HttpPost]
    public ActionResult MethodName(String Answer)
    {
        return RedirectToAction("ViewName");
    }
