Question

所以我在标题中收到错误消息，但我不明白为什么。

此处介绍了如何在视图中引用模型

@model IEnumerable<Lowflix.Models.LendingIndexModel>

此foreach中出现的错误

 @foreach (var item in Model)

由于我什至宣布了IEnumerable，因此我无法向自己解释这个错误。它包含多个对象。

这是错误消息：

foreach statemetn cannot operate on variables
of type "Models" because "Models" does not 
contain  a public instance of GetEnumerator

- 型号：

using Lowflix.Core.Entities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace Lowflix.Models
{
    public class LendingIndexModel
    {
        public LendingIndexModel()
        {
        }
        public Guid LendingId { get; set; }
        public Guid CustomerId { get; set; }
        public Guid CopyId { get; set; }

        public String Title { get; set; }


        public DateTime StartDate { get; set; }
        public DateTime? ReturnDate { get; set; }


        public virtual Movie Movie { get; set; }
        public virtual Customer Customer { get; set; }
        public virtual Copy Copy { get; set; }

}

调试模型：型号：

    +       Model   {System.Linq.Enumerable.WhereSelectListIterator
<Lowflix.Core.Entities.Lending,
 Lowflix.Models.LendingIndexModel>} System.Collections.Generic.IEnumerable
<Lowflix.Models.LendingIndexModel> 

{System.Linq.Enumerable.WhereSelectListIterator
<Lowflix.Core.Entities.Lending, 
Lowflix.Models.LendingIndexModel>}

Answer 1

请尝试以下代码。

@model List<Lowflix.Models.LendingIndexModel>

在“查看”页面中，将IEnumerable更改为List。
