asp.net-mvc-4 - 如何在 mvc4 中将 Json 字符串发送到 Controller 并反序列化 json

Question

我有如下的 json 对象

Extension = {
"BookMarks":
[{"Name":"User1","Number":"101"},
{"Name":"User2","Number":"102"},
{"Name":"User3","Number":"103"}]}

我想将此 json 字符串发送到我的 Controller Action 方法并反序列化数据

我想将数据传递给部分 View

 public ActionResult ExtensionsDialog(var data)
        {
            return PartialView(data); 
        }

任何帮助
提前致谢..

在您的 查看 :

function SendData(){
        var dataToSend = JSON.stringify(data);

        $.ajax({
            type: "POST",
            url: '@Url.Action("YourAction", "YourController")',
            dataType: "json",
            data: dataToSend,
            contentType: "application/json; charset=utf-8",

        });
}

$("#Updatebtn").click(function () {

             sendData(); 
});

在你 型号 :

public class YourModel
{
  public String Name { get; set; }
  public int Number { get; set; }
}

在您的 Controller :

[HttpPost]
public ActionResult YourAction()
        {
            var resolveRequest = HttpContext.Request;
            List<YourModel> model = new List<YourModel>();
            resolveRequest.InputStream.Seek(0, SeekOrigin.Begin);
            string jsonString = new StreamReader(resolveRequest.InputStream).ReadToEnd();
            if (jsonString != null)
            {
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                model = (List<YourModel>)serializer.Deserialize(jsonString, typeof(List<YourModel>);
            }
          //Your operations..
         }

希望这可以帮助。
