c# – 如何遍历从JsonResult方法返回的Dictionary？

我有一个 JavaScript方法,它对控制器方法进行AJAX调用.
此控制器方法是一个JsonResult方法,它将字典对象返回给我的JavaScript.但是我对这个对象做的任何事情(比如,dictionaryObject.count,dictionaryObejct [i] .value等)给了我“undefined”.有关如何使用此对象的任何想法？

function MakeControllerMethodCallFunction(stringParam1,stringParam2) {
    // Remove all rows from table so that table can have latest data
    $('#TableModal tr').each(function (i,row) {
        var $row = $(row);

        $row.remove();
    });

    $("#TableModal thead").append("<tr><th>" + stringParam1+ " Details " + "</th></tr>");

    //Resolving the server side method URL
    var websitePath = GetRootWebSitePath();
    var getUrl = websitePath + "/Home/GetDetails";

    //Creating parameters for Ajax call
    var params = "{"ParamOne" : "" + stringParam1+ "","ParamTwo" : "" + stringParam2+ "" }";

    //AJAX Call
    $.ajax({
        url: getUrl,type: 'POST',dataType: 'json',contentType: 'application/json; charset=utf-8',data: params,success: MakeControllerMethodCallFunction_Success,error: function (xhr,status,thrownError) {
            alert("Get Details error");
        }
    });
}

//On Success of MakeControllerMethodCallFunction() this will be hit and values will be bind to the table
function MakeControllerMethodCallFunction_Success(dictionaryObject) {
    var Size = 0;
    if (dictionaryObject!= null) {

        Size = (dictionaryObject!= null) ? dictionaryObject.count : 0;
    }

    if (Size != null) {

        for (var i = 0; i < Size; i++) {

            var newRow = "<tr>";

            if (dictionaryObject!= null && dictionaryObject.count> 0 && dictionaryObject[i] != null) {
                newRow += "<td>" + dictionaryObject[i].name + "</td>" + "<td>" + dictionaryObject[i].value + "</td>";

            }
            else {
                newRow += "<td></td>";
            }
            newRow += "</tr>";
            $("#TableModal tbody").append(newRow);
        }
    }
}

public ActionResult GetDetails()
{
    var result = new Dictionary<string,string>
    {
        { "key1","value1" },{ "key2","value2" },{ "key3","value3" },};

    return Json(result,JsonRequestBehavior.AllowGet);
}

{"key1":"value1","key2":"value2","key3":"value3"}

function MakeControllerMethodCallFunction_Success(dictionaryObject) {
    for (var key in dictionaryObject) {
        if (dictionaryObject.hasOwnProperty(key)) {
            var value = dictionaryObject[key];
            alert(key + " -> " + value);
        }
    }
}
