c# - 通过 Entity Framework Core 将列表传递给 View

Question

我想将产品列表传递给我的 View 。但我不知道我在这里错过了什么。当我运行它时，我遇到了这个异常

InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'System.Runtime.CompilerServices.AsyncTaskMethodBuilder1+AsyncStateMachineBox1[System.Collections.Generic.IList1[DataLayers.Models.mymodel],DataLayers.Services.Repository+d__2]', but this ViewDataDictionary instance requires a model item of type 'System.Collections.Generic.IEnumerable`1[DataLayers.Models.mymodel]'.

这是我的IRepository

Task<IList<mymodel>> GetAllProductsAsync();

这是我的Repository(为简单起见省略了上下文注入(inject))

public async Task<IList<mymodel>> GetAllProductsAsync()
    {
        return await _context.mymodel.ToListAsync();
    }

这是MyController

private readonly IRepository _IRepository;
public MyController(IRepository ThisController)
{
      _IRepository = ThisController;
}


public IActionResult Products()
{
  return View(_IRepository.GetAllProductsAsync());
}

最后这是 myView

@model IEnumerable<DataLayers.Models.mymodel>
<table>
    @foreach (var item in Model)
        {
            <tr class="table-row">
                <td>
                    <img src="@Html.DisplayFor(m => item.DishImg)">
                </td>
                <td>
                    <p>@Html.DisplayFor(m => item.Productname)</p>
                </td>
                <td>
                    <p>@Html.DisplayFor(m => item.ProductInfo)</p>
                </td>
                <td>
                    <p>@Html.DisplayFor(m => item.ProductPrice)</p>
                </td>
            </tr>
        }
</table>

考虑改变:

public IActionResult Products()
{
  return View(_IRepository.GetAllProductsAsync());
}

收件人:

public async Task<IActionResult> Products()
{
  return View(await _IRepository.GetAllProductsAsync());
}
