传递给WEb API Action时，在JSON中丢失值(Losing values in JSON when passing to WEb API Action)

 我有一个具有一些属性的对象（A），其中一个属性是一个较低类型的列表（B）。 
 
 我有一个Web API Action，它接受一个A对象作为参数。 
 
 我只是测试我可以通过JSON儿子传递这个对象我有一个带有一些Javascript的webform，如下所示....... 
 
    var tmpData = {
        lid: "f8fdb980-ccb8-4a54-9b83-b73dd2d569ca",
        aid: "8f6efc68-d747-42a4-b7d4-218951b66a97",
        bid: "e9f5e5d2-5d3d-41ac-89dc-7586ec2a5286",
        ps: []
    };
    tmpData['ps'].push({ "cid": "5a664dcc-8281-41f1-b81c-ae49499e12b8", "d": 5, "q": 2 });
    tmpData['ps'].push({ "cid": "4e9a30e0-c741-4708-88d7-8db4941c17cc", "d": 10, "q": 2 });

    var myJSON = JSON.stringify(tmpData);

    //Call the action to get the list in JSON format
    url = "http://localhost:64878/home/TakeTestBasketAddItemsRequest";
    $.ajax({
        url: url,
        type: 'POST',
        cache: false,
        data: myJSON,
        success: function (resultantData) {
            var s = resultantData;
            pResults.innerHTML = s;
        }
    });
 
 这将导致操作OK，并且对象在“ps”属性中有2个项目。 然而，这两个项目中的值丢失了，我留下了零/未初始化的值。 
 
 我是否丢失了列表项的值？ 
 
 为清楚起见 - 这里也是我的行动。 
 
    [HttpPost]
    public ActionResult TakeTestBasketAddItemsRequest(ECodeBasketRequest model)
    {
        try
        {
            var sb = new StringBuilder();
            sb.AppendLine(String.Format("LocationBridgeId: {0}{1}", model.lid, Environment.NewLine));
            sb.AppendLine(String.Format("ApplicationBridgeId: {0}{1}", model.aid, Environment.NewLine));
            sb.AppendLine(String.Format("BasketId: {0}{1}", model.bid, Environment.NewLine));
            foreach (var p in model.ps)
            {
                sb.AppendLine(String.Format("CategoryBridgeId: {2} Denomination: {0} Quantity: {1}{3}", p.d, p.q, p.cid, Environment.NewLine));
            }
            return Content(sb.ToString());
        }
        catch (Exception ex)
        {
            return Content(string.Format("Problem: {0}", ex.ToString()));
        }
    }
 
 正如我所说的那样，我现在只是在测试，所以我希望能够深入了解这一点。 感谢先生，Ant 

I have an object (A) with a few properties, one of which is a LIST of abother type (B).
 
I have a Web API Action that takes in an A object as a parameter.
 
I am just testing that I can pass this object via JSON son I have a webform with some Javascript on it as follows.......
 
    var tmpData = {
        lid: "f8fdb980-ccb8-4a54-9b83-b73dd2d569ca",
        aid: "8f6efc68-d747-42a4-b7d4-218951b66a97",
        bid: "e9f5e5d2-5d3d-41ac-89dc-7586ec2a5286",
        ps: []
    };
    tmpData['ps'].push({ "cid": "5a664dcc-8281-41f1-b81c-ae49499e12b8", "d": 5, "q": 2 });
    tmpData['ps'].push({ "cid": "4e9a30e0-c741-4708-88d7-8db4941c17cc", "d": 10, "q": 2 });

    var myJSON = JSON.stringify(tmpData);

    //Call the action to get the list in JSON format
    url = "http://localhost:64878/home/TakeTestBasketAddItemsRequest";
    $.ajax({
        url: url,
        type: 'POST',
        cache: false,
        data: myJSON,
        success: function (resultantData) {
            var s = resultantData;
            pResults.innerHTML = s;
        }
    });
 
This gets to the action OK and the object has 2 items in the "ps" property. Howeverm the values in these 2 items are lost and I am left with zeros / uninitialised values.
 
Whay am I losing the values of the list items?
 
For clarity - here is my Action also. 
 
    [HttpPost]
    public ActionResult TakeTestBasketAddItemsRequest(ECodeBasketRequest model)
    {
        try
        {
            var sb = new StringBuilder();
            sb.AppendLine(String.Format("LocationBridgeId: {0}{1}", model.lid, Environment.NewLine));
            sb.AppendLine(String.Format("ApplicationBridgeId: {0}{1}", model.aid, Environment.NewLine));
            sb.AppendLine(String.Format("BasketId: {0}{1}", model.bid, Environment.NewLine));
            foreach (var p in model.ps)
            {
                sb.AppendLine(String.Format("CategoryBridgeId: {2} Denomination: {0} Quantity: {1}{3}", p.d, p.q, p.cid, Environment.NewLine));
            }
            return Content(sb.ToString());
        }
        catch (Exception ex)
        {
            return Content(string.Format("Problem: {0}", ex.ToString()));
        }
    }
 
As I said, I am just testing at the moment so would love to get to the bottom of this. Thanks in advace, Ant
