Asp.net 为什么我的C#web服务没有获取我的JSON数组数据？

我使用AJAX将JSON数组传递给.NETWeb服务。Stringified JSON数组在发送时是正确的-我在JS警报中显示内容-但是当我在web服务中输出它时，它只显示空值

救命啊

JS是这样的：

                var listitems = [];
                $('#job-item-list').children('.iamalistitem').each(function () {
                    listitems.push({ "title": $(this).find('.job-item-title').text(), "price": $(this).find('.job-item-price').text().replace("£","").replace("£","") });
                });
                alert(JSON.stringify({ ListItems: listitems }));

                $.ajax({
                    type: "POST",
                    url: "/ld_jobs.asmx/putJobItems",
                    // The key needs to match your method's input parameter (case-sensitive).
                    data: JSON.stringify({ ListItems : listitems }),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (response) {
                        var responseObjTwo = JSON.parse(response.d);
                        //showUserMessage(responseObjTwo.Message, false);
                        showUserMessage(response.d, false);
                    },
                    error: function (response) {
                        var responseObj = JSON.parse(response.responseText);
                        showUserMessage(responseObj.Message, true);
                    }
                });

接收服务如下所示：

    public class ListItem
    {
        public string itemTitle { get; set; }
        public decimal itemPrice { get; set; }
    }

    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string putJobItems(ListItem[] ListItems)
    {
        // Add to DB
        int errorNumber = 0;
        try
        {
            // check if on DB already
            string returnstring = "";
            errorNumber++; //1
            foreach (ListItem item in ListItems)
            {
                errorNumber++; //2,3,4
                returnstring += "Desc: " + item.itemTitle + "; Price: " + item.itemPrice.ToString() + "; ";
            }
            errorNumber++; //5
            return "{ \"Status\" : \"Success\", \"Message\" : \"Your request has been successfully posted.  Well done you.  Go put the kettle on and be lazy! \", \"input\" : \"" + returnstring + ": " + errorNumber.ToString() +  "\" }";
        }
        catch (Exception ex)
        {
            Exception newEx = new Exception("Well this is quite embarassing.  It seems the badgers have escaped! (Actual error: " + ex.Message + "; error: " + errorNumber.ToString() + ")");
            throw newEx;
        }
    }

进入的严格化现场是：

{"ListItems":[{"title":"(Groceries) 4 pints of milk","price":"2.00"},{"title":"(Groceries) 2 loafs of bread","price":"3.00"},{"title":"(Subway) Foot Long BMT","price":"3.00"}]}

答复d返回为：

{ "Status" : "Success", "Message" : "Your request has been successfully posted. Well done you. Go put the kettle on and be lazy! ", "input" : "Desc: ; Price: 0; Desc: ; Price: 0; Desc: ; Price: 0; : 5" }

非常感谢您的帮助。谢谢。

您在客户端使用

title

和

price

属性名称，但在服务器上使用

itemttitle

和

itemPrice

。调整它们以使用相同的名称。

是否调试并检查是否在web服务中的listItem中获取数据？我有，但值不存在，但我无法确定的是，它在listItem[]数组中始终具有正确的项数，但是它们都是空的…我不明白为什么它不会收到实际的数据，但是列表中仍然有正确的项目数？正如你发布的那样，我已经知道了！新手失误！谢谢现在一切正常！**有点尴尬**
