如何从WebAPI返回字典?

我有一个MVC项目,该视图从一个视图上传一个或多个文件到服务器, 然后,当我单击“提交”时,将撤回一个证明的Web服务,并传递一组文件进行上传。 上载工作正常,但从webapi表单中,我有一个我要返回的对象(类Store)。

我不知道从网络api返回“原始”对象是错误还是读取错误。

这是我的模特

    public class Store
    {
        public IDictionary<string, string> dictionaryOfStores = new Dictionary<string, string>();
        public string CodeText { get; set; }
    }

这是我的网络api方法:

public async Task<ActionResult<Store>> UploadAsync()
        {
            dictStores = new Store();
            foreach (var formFile in form.Files)
                    {

                        dictStores.dictionaryOfStores.Add(formFile.FileName, codefilename);
                        // also CodeText is filled here
                    }
                }
            }

            // return dictionary
            //

            return dictStores;
        }

这是我的MVC控制器,可调用私有Web服务

  public async Task<IActionResult> Upload(List<IFormFile> files)
        {

                    using (var client = new HttpClient())
                    {

                            var model = new FilesViewModel();
                            MultipartFormDataContent multiContent = new MultipartFormDataContent();
                            foreach (var formfile in files)
                            {
                                client.BaseAddress = new Uri(BaseAddress);
                                byte[] data;
                                using (var br = new BinaryReader(formfile.OpenReadStream()))
                                    data = br.ReadBytes((int)formfile.OpenReadStream().Length);
                                ByteArrayContent bytes = new ByteArrayContent(data);

                                multiContent.Add(bytes, "file", formfile.FileName);
                                model.Files.Add(new FileDetails { Name = formfile.GetFilename() });
                            }
                            var result = await client.PostAsync("api/Load/Upload", multiContent); // 
                            // here i have try to read result.Content but doesn't have my data
                            var res = await result.Content.ReadAsStreamAsync();
                            // here i have to put res in my model
                            return View("Summary", model);

                    }

也许是这样

IDictionary<MyClass, int> resource = new Dictionary<MyClass, int> 
{
  { new Class {Property1="1"}, 1 },
  { new Class {Property1="11"}, 1 }
};

return Ok(resource);

我通过看到答案来解决:How to get object using Httpclient with response Ok in Web Api 我能够读取数据:

await result.Content.ReadAsAsync<Store>()
