当页面继承自IEnumerable< T>时，我可以使用LabelFor()吗? [英] Can I use LabelFor() when the page inherits from IEnumerable<T>?

问题描述

比方说，我有以下类定义:

Let's say, I've the following class definition:

public class Person
{
  [DisplayName("First Name")]
  public string FirstName { get; set; }
  [DisplayName("Last Name")]
  public string LastName { get; set; }
}

而且，我想使用 LabelFor(x => x.FirstName)，依此类推.不幸的是，页面继承自

And, I'd like to use LabelFor(x =>x.FirstName), and so on. Unfortunately, the page inherits from

IEnumerable<T>

因此无法使用lambda表达式.有工作区吗?还是我必须使用 Label(String)版本?

so there's no way to use lambda expression. Is there any workarround? Or, I do have to use the Label(String) version?

感谢您的帮助

推荐答案

@Html.LabelFor(model => model.FirstOrDefault().LastName)

这将允许您处理列表为空时的情况...非常适合列标题.您只需要检查列表为空的情况.

This will allow you to handle when the list is empty... very suitable for column headers. All you should check is for the cases when the list is null.
