消费JSON POST到MVC控制器

Question

I built the CSharp class Visual Studios "Paste Special" --> Json to Classes. I would post the jsonData but it is fairly large and dont want to waste your time. I'm guessing my cihForm.cs needs a constructor class but that didn't seem like the right way to go about consuming the data.

The problem seems to be that the cihForm class is not consuming the json data correctly. I assume it is because of the cihForm structure.

View Ajax call:

var jsonData = JSON.stringify(data);

$.ajax({
    url: '/Forms/Create_Post',
    type: 'POST',
    dataType: 'json',
    data: jsonData,
    contentType: 'application/json; charset=utf-8',
    success: function (data) {
        // get the result and do some magic with it
        var message = data.Message;
        console.log(message);
    }
});

Controller Action:

<HttpPost>
<ActionName("Create")>
Function Create_Post(jsonData As Rootobject) As JsonResult
  //jsonData seems to be blank
  // immediate window debug below
  //?jsonData
  //{CIH.Library.CSharp.cihForm}

End Function

Csharp Class:

namespace CIH.Library.CSharp
{

        public class Rootobject
        {
            public Theform theForm { get; set; }
        }

        public class Theform
        {

Answer 1

It was an issue with how i was passing the class into my controller function.

This is how i went about fixing it.

1) Create JSON template using this website -- http://www.objgen.com/json

2) Create C# classes using this website -- http://json2csharp.com/

3) Create <script> tag on view page that does ajax call with json data

   <button type="button" onclick="submitForm()">Save</button>

    <script type="text/javascript">
        function submitForm() {

            var data = //paste JSON template created in step #1 here
            var jsonData = JSON.stringify(data);

        $.ajax({
            url: '/Forms/Create_Post',
            type: 'POST',
            dataType: 'json',
            data: jsonData,
            contentType: 'application/json; charset=utf-8',
            success: function (data) {
                // get the result and do some magic with it
                var message = data.Message;
                console.log(message);
            }
        });
    </script>

3) I pasted the classes created in step 2 into a class file.

4) in my controller i then passed in RootObject

   <HttpPost>
    <ActionName("Create")>
    Function Create_Post(jsonData As RootObject) As ACtionResult

        Dim json As New RootObject()
        json = JsonConvert.DeserializeObject(Of RootObject)(jsonData.ToString())


    End Function
