c# - 如何在 View 中处理列表、集合或 IEnumerable

Question

大家好谁能帮我...我对 c# 和 mvc 很陌生

模型是:

public class CatagoryModel {
    public int Id { get; set; }
    public string  CName { get; set; }
}

Controller 是:

   public ActionResult catagory() {
        var c = new CatagoryModel();
        var URL="";

        HttpWebRequest req = WebRequest.Create(URL)
                   as HttpWebRequest;
        string result = null;
        using (HttpWebResponse resp = req.GetResponse()
                                      as HttpWebResponse)
        {
            StreamReader reader =
                new StreamReader(resp.GetResponseStream());
            result = reader.ReadToEnd();
        }


        var categories = JsonConvert.DeserializeObject<List<CatagoryModel>>(result);

        return View(categories);
      }

像这样的 View

@model MvcApplication1.Models.CatagoryModel
<ul>
@foreach(var k in Model){
   <li>@k.Id</li> 
    <li>@k.CName</li>

}

我不知道出了什么问题...
它在渲染 View 时显示错误..

好吧，如果你的模型是Enumerable，那么在你看来，它一定是可枚举的!

@model IEnumerable<MvcApplication1.Models.CatagoryModel>
