我在打印验证时遇到了一个问题在视图中输入字段

我有一个视图，希望用户在其中填写表单。以这种形式我在用户可以继续之前，需要验证输入。在我的数据库模型中我对如何验证代码设置了不同的规则。在里面我尝试使用显示错误消息的视图 Html.Validationsummary（true）

它在早期的一个项目中工作得非常好。但这次不是

下面是DbModel类

变量名是挪威语的，没关系。代码仍然有效在任何语言中都相同：）

我的控制器

那景色呢

谁能帮我找出我做错了什么

Yo创建新块try catch DbEntityValidationException：

catch (DbEntityValidationException exDbEntityValidationException)

例如：

catch (DbEntityValidationException exDbEntityValidationException)
{
   DbEntityValidationException exval = exDbEntityValidationException;

   StringBuilder sb = new StringBuilder();

   foreach (var excep in exval.EntityValidationErrors)
   {
       sb.AppendFormat("YourField: {0} {1}",((YourEntityType)excep.Entry.Entity).YourField, Environment.NewLine);

       excep.ValidationErrors.ToList().ForEach(v => sb.AppendFormat("   Field: {0} -  {1}{2}", v.PropertyName, v.ErrorMessage, Environment.NewLine));
   }

      System.Diagnostics.Debug.Print(sb.ToString());
}
