从javascript发送json到asp.net

Question

I have a web app where the backend is made in ASP.net. The ajax call is a normal get request

$.ajax({
    url: 'myurl/updatejson',
    contentType: "application/json; charset=utf-8",
    data: data,
    success: function (data) {
        // do something
    },
    error: function (xhr, status, err){
        console.error(xhr, status, err);
    }
});          

Where data is a simple key, value object correctly formatted. The C# backend is

public HttpStatusCodeResult UpdateJson(Dictionary<string, object> json){ //do something }

from this i was expecting that json in c# would be equal to key, value but instead i get key, [value] for some reason. If i declare the Dictionary as Dictionary<string, string> instead of Dictionary<string, object> everything works fine and i get the expected result, so it mean that for some reason is converting the string to object wrapping it in an array.

How can i use the dictionary<string, object> (because the value could be a string, int or boolean) without having the value wrapped in an array?

Have you tried to use dynamic type resolution ?

 public HttpResponseMessage UpdateJson([FromBody]dynamic value){
    ...
    Console.WriteLine(value["field1"]);
 }
