将Json反序列化为C＃列表(Deserializing Json to C# list)

 我试图将JSON反序列化为C＃列表。 我有Jquery代码， 
 
    $(document).ready(function () {
        $("#btn_check").click(function () {
            var str="";
            x = $("#frm").serializeArray();
            $("#Label1").empty();
            $.each(x, function (i, field) {
              //  $("#Label1").append(field.name + ":" + field.value + " ");

                str = str + field.name + ":" + field.value + " ";

            });
            var jsonstr=JSON.stringify(str);            });
    });
 
 字符串化后，我得到一些奇怪的jsonstr = __VIEWSTATE：/ wEPDwUKLTg = __VIEWSTATEGENERATOR：172284EE __EVENTVALIDATION：/ wEWNAKauo6nDAK5rJ0YAp7D / 4IGAoPa4e0LAujww9gBAs2HpsMHArKeiK4NApe16pgDAvzLzIMJApH2i8IBAvaM7qwHAp7Dv7UBAp7Dq9oIAp7Dl / 8PAp7Dg6QHAp7Dj6IEAp7D + 8YLAp7D5 + sCAp7D05AKAp7Dn9wLAp7Di4EDAoPaoaAHAoPajcUOAoPa + ekFAoPa5Y4NAoPa8YwKAoPa3bEBAoPaydYIAoPatfsPAoPagccBAoPa7esIAujwg4sNAujw768EAujw29QLAujwx / kCAujw0 / cPAujwv5wHAujwq8EOAujwl + YFAujw47EHAujwz9YOAs2H5vUCAs2H0poKAs2Hvr8BAs2HquQIAs2HtuIFAs2HoocNAs2HjqwEAs2H + tALAs2HxpwNAs2HssEEAvCFnqIPppJbhAvF8AzSoMd / uZfiRXpzWu0 = check_0：上check_1：上check_2 ：on check_3：on check_5：on check_6：on check_7：on check_8：on check_9：on check_10：on check_11：on check_12：on check_13：on check_14：on check_15：on check_16：on check_17：on check_18：on check_19：on check_20：on check_22：on check_23：on check_24：on check_25：on check_26：on check_27：on check_28：on check_29：on check_30：on check_31：on check_32：on check_33：on check_34：on check_35：在检查 _36：on check_37：on check_39：on check_40：on check_41：on check_42：on check_43：on check_44：on check_45：on check_46：on check_47：on check_48：on check_49：on 
 
 check_0到check_1是动态创建的复选框，我想在C＃中以列表或任何形式获取它们的值来解释并将它们推送到数据库中。 
 
 asp.net： 
 
<form id="frm" runat="server">

    <asp:Panel ID="pnl_seat" runat="server">
        <asp:PlaceHolder ID="plhdr_seat" runat="server">
         checkboxes are dynamically created here
       </asp:PlaceHolder>
        <br />
        <button id="btn_check" type="button">Serialize form values</button>
        <asp:Button ID="btn_submit" runat="server" Text="Submit"  OnClick="btn_submit_Click" />
        <br />

        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />

    </asp:Panel>

</form>

 C＃代码： 
 
 using Newtonsoft.Json;
class abc // some class
{   
    protected void btn_submit_Click(object sender, EventArgs e)
    {
        List<Test> myDeserializedObjList = (List<Test>)   Newtonsoft.Json.JsonConvert.DeserializeObject(Request["jsonstr"], typeof(List<Test>));
    }
 }
 
 上面的代码我是从codeproject.com得到的。 但是在运行此代码时，我得到一个异常，即“str”为“null”。 如何将label1或str推送到服务器端？ 请帮帮我。 

I am trying to deserialize JSON to C# list. I have the Jquery code as,
 
    $(document).ready(function () {
        $("#btn_check").click(function () {
            var str="";
            x = $("#frm").serializeArray();
            $("#Label1").empty();
            $.each(x, function (i, field) {
              //  $("#Label1").append(field.name + ":" + field.value + " ");

                str = str + field.name + ":" + field.value + " ";

            });
            var jsonstr=JSON.stringify(str);            });
    });
 
after stringify, I get something weird as jsonstr= __VIEWSTATE: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 __VIEWSTATEGENERATOR:172284EE __EVENTVALIDATION:/wEWNAKauo6nDAK5rJ0YAp7D/4IGAoPa4e0LAujww9gBAs2HpsMHArKeiK4NApe16pgDAvzLzIMJApH2i8IBAvaM7qwHAp7Dv7UBAp7Dq9oIAp7Dl/8PAp7Dg6QHAp7Dj6IEAp7D+8YLAp7D5+sCAp7D05AKAp7Dn9wLAp7Di4EDAoPaoaAHAoPajcUOAoPa+ekFAoPa5Y4NAoPa8YwKAoPa3bEBAoPaydYIAoPatfsPAoPagccBAoPa7esIAujwg4sNAujw768EAujw29QLAujwx/kCAujw0/cPAujwv5wHAujwq8EOAujwl+YFAujw47EHAujwz9YOAs2H5vUCAs2H0poKAs2Hvr8BAs2HquQIAs2HtuIFAs2HoocNAs2HjqwEAs2H+tALAs2HxpwNAs2HssEEAvCFnqIPppJbhAvF8AzSoMd/uZfiRXpzWu0= check_0:on check_1:on check_2:on check_3:on check_4:on check_5:on check_6:on check_7:on check_8:on check_9:on check_10:on check_11:on check_12:on check_13:on check_14:on check_15:on check_16:on check_17:on check_18:on check_19:on check_20:on check_21:on check_22:on check_23:on check_24:on check_25:on check_26:on check_27:on check_28:on check_29:on check_30:on check_31:on check_32:on check_33:on check_34:on check_35:on check_36:on check_37:on check_38:on check_39:on check_40:on check_41:on check_42:on check_43:on check_44:on check_45:on check_46:on check_47:on check_48:on check_49:on 
 
check_0 to check_1 are the dynamically created checkboxes and I want to get their values in C# as list or in any form to interpret and push them into Database.
 
asp.net:
 
<form id="frm" runat="server">

    <asp:Panel ID="pnl_seat" runat="server">
        <asp:PlaceHolder ID="plhdr_seat" runat="server">
         checkboxes are dynamically created here
       </asp:PlaceHolder>
        <br />
        <button id="btn_check" type="button">Serialize form values</button>
        <asp:Button ID="btn_submit" runat="server" Text="Submit"  OnClick="btn_submit_Click" />
        <br />

        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />

    </asp:Panel>

</form>

    {
        List<Test> myDeserializedObjList = (List<Test>)   Newtonsoft.Json.JsonConvert.DeserializeObject(Request["jsonstr"], typeof(List<Test>));
    }
 }
 
the above code I got it from codeproject.com. But on running this code, I am getting an exception that "str" as "null". How to push the label1 or str to server side? Help me please.
