c# - 如何访问 MVC .net 核心中返回的 Controller 的字段结果

Question

虽然我的 Controller 功能正常，但我在 .Name 的“Assert”行的单元测试中遇到语法错误

IAction result does not contain a definition for "Name"...

如果我在 Debug模式下将鼠标悬停在“结果”上，我可以看到数据在结果变量中(结果 > 模型 > 名称)。我试过使用 Result.Model.Name 访问它，但这也是一个语法错误。

单元测试:

    [Fact]
    public async Task TestGetNameById()
    {
        string expectedName = "Component";

        using (var context = GetContextWithData())
        using (var controller = new AssetTypesController(context))
        {
            var result = await controller.Details(2);
            Assert.Equal(expectedName, result.Name);
        }
    }

Controller Action :

   public async Task<IActionResult> Details(int? id)
    {
        if (id == null)
        {
            return NotFound();
        }

        var assetType = await _context.AssetType
            .SingleOrDefaultAsync(m => m.AssetTypeId == id);
        if (assetType == null)
        {
            return NotFound();
        }

        return View(assetType);
    }

模型

public class AssetType
{
    [DatabaseGenerated(databaseGeneratedOption: DatabaseGeneratedOption.Identity)]
    [Key]
    public int AssetTypeId { get; set; }
    [Required]
    public string Name { get; set; }
}

那是因为 IActionResult 不是 AssetType 的类型。

尝试这样的事情:

[Fact]
public async Task TestGetNameById()
{
    string expectedName = "Component";

    using (var context = GetContextWithData())
    {
        var controller = new AssetTypesController(context);
        var result = await controller.Details(2) as ViewResult;
        var assetType = (AssetType) result.ViewData.Model;
        Assert.Equal(expectedName, assetType.Name);
    }
}
