我很难显示从列表对象模型到视图的值。

我尝试使用此代码显示它

@model IEnumerable<MVC.Models.RootObject>

@foreach (var item in @Model)
{
    <li>@item.records</li>
}


但是显示错误

传递到字典中的模型项的类型为“ MVC.Models.RootObject”,但是此字典需要模型类型为“ System.Collections.Generic.IEnumerable`1 [MVC.Models.RootObject]”的模型项。

这是我用来将数据从模型传递到视图的控制器

           var transno = "ST-100420190001";

            var client = new HttpClient();
            var httpRequestMessage = new HttpRequestMessage
            {
                Method = HttpMethod.Get,
                RequestUri = new Uri("https://myurl.com/" + transno),
                Headers = {
                { HttpRequestHeader.Accept.ToString(), "application/json" },
                { HttpRequestHeader.ContentType.ToString(), "application/json"},
                { "client-id", "client_id"},
                { "client-secret","client_secret"},
                { "partner-id","partner_id"},
                { "X-Version", "1" }
            }
            };

            var response = client.SendAsync(httpRequestMessage).Result;
            RootObject obj = JsonConvert.DeserializeObject<RootObject>(await
            response.Content.ReadAsStringAsync());

            return View(obj);


RootObject模型如下所示

public class RootObject
    {
        public List<Record> records { get; set; }
        public int totalRecords { get; set; }
    }


然后,记录模型如下所示

 public class Record
    {
        public string transferId { get; set; }
        public string type { get; set; }
        public DateTime createdAt { get; set; }
        public string dateUpdated { get; set; }
        public string state { get; set; }
        public string senderTransferId { get; set; }
    }

最佳答案

好吧,让我们看看错误消息

您的视图期望使用IEnumerableRootObject,但是您只传递了一个RootObject。

The model item passed into the dictionary is of type 'MVC.Models.RootObject', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[MVC.Models.RootObject]'.

我不确定您的API会回复什么,但是您可能需要DeserializeObjectIEnumerableRootObject而不是单个对象。您是否尝试调试这些线路?

var response = client.SendAsync(httpRequestMessage).Result;
RootObject obj = JsonConvert.DeserializeObject<RootObject>(await response.Content.ReadAsStringAsync());

return View(obj);


如果不是这种情况,并且您希望以后进行多个API调用以建立列表

像这样的东西应该可以工作,但是我建议您遵循上面的内容,因为从您发布的剃须刀来看,这似乎是您正在寻找的更多东西。

var response = client.SendAsync(httpRequestMessage).Result;
RootObject obj = JsonConvert.DeserializeObject<RootObject>(await
response.Content.ReadAsStringAsync());

IEnumerable<RootObject> list = new List<RootObject>(){ obj };

return View(list);
