<?xml version="1.0" encoding="UTF-8"?>
<Root>
 <Item id="1" type="province" value="Province A">
   <Item id="101" type="district" value="District A">
     <Item id="10101" type="precinct" value="Precinct A" />
     <Item id="10102" type="precinct" value="Precinct B" />
     <Item id="10103" type="precinct" value="Precinct C" />
   </Item>
   <Item id="102" type="district" value="District B">
     <Item id="10201" type="precinct" value="Precinct D" />
     <Item id="10202" type="precinct" value="Precinct E" />

                ModelState.AddModelError("", "Failed!");
            }
        }
        return View(model);

    }

这是我的RegisterModel.cs

    public class RegisterModel
{
    [Key]
    public long ID { set; get; }     
    [Required(ErrorMessage = "Do not Skip this")]
    public string UserName { set; get; }
