如何将 JSON 字符串从 ASP.Net 传递到 WebAPI 获取方法？

Question

我有一个如下所示的 WebAPI Get 方法

// GET api/Employee/5
public tblEmployee GettblEmployee(int id)
{
    tblEmployee tblemployee = db.tblEmployees.Find(id);
    if (tblemployee == null)
    {
        throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotFound));
    }

     return tblemployee;
 }

我正在尝试从 ASP.NET 互联网应用程序调用它

HttpClient hc;
hc = new HttpClient();
string uriStr = "http://localhost/api/Employee/";

HttpResponseMessage response = hc.GetAsync(uriStr + "2").Result;

var obj = JsonConvert.DeserializeObject(response.Content.ReadAsStringAsync().Result);

ViewBag.Message = obj.ToString();
return View();

现在我想将 JSON 从 ASP 网站传递到 WebAPI，有人可以帮助我吗？我用谷歌搜索了很多，但我只能找到来自 JQuery 的调用

您可以使用PostAsJsonAsync

using (HttpClient hc = new HttpClient())
            {
                var myModel = new Model()
                {
                prop1 = "prop1", prop2 = 1, prop3 = "prop3"
                };
                HttpResponseMessage response = await client.PostAsJsonAsync("api/Employee/", myModel);
                if (response.IsSuccessStatusCode)
                {

                }
            }
