asp.net mvc 3剃须刀从IEnumerable获取一个元素 [英] asp.net mvc 3 razor get one element from IEnumerable

问题描述

我的视图模型(LIST)如下:

I my view model(LIST) looks like this:

public class ConversationModel 
    {
        public int ID { get; set; }
        public string Body { get; set; }
        public DateTime Datetime { get; set; }
        public string Username { get; set; }
        public string ImgUrl { get; set; }
        public string ToUserID{ get; set; }
    }

这是我的观点

@model IEnumerable<NGGmvc.Models.ConversationModel>

如何在当前位置获取ToUserID?像这样的东西

how i can get ToUserID on current postion? something like this

@Model [0] .ToUserID

@Model[0].ToUserID

谢谢

推荐答案

您应该可以:

@Model.First().ToUserID

请注意，您可能想先检查可枚举中是否有任何项目，就像没有一样，然后First()将返回null

Note, you may want to check whether there are any items in the enumerable first as if there aren't, then First() will return null

(注意，因为您的问题中有@Model [0]，所以我假设您正在专门尝试获取第一个值.我可能杆子的末端错了，在这种情况下，雅库布的答案应该可以解决您的问题！ )

(Note, because you had @Model[0] in your question, I assume you are specifically trying to get the first value. I may have the wrong end of the stick, in which case Jakub's answer should sort you out!)
