Pass array to WebMethod using jQuery AJAX and save array value in Database using C# in ASP.Net

I am trying to save array of data in database how to achieve it. Here I have a form where three inputs PRODUCT_ID, TDC_NO, REVISION are there along with array list of values generated dynamically(sizeMin ,sizeMax ,tolMin ,tolMax ).I want to store those dynamically generated values in “Prop_detail” whose structure I have mentioned at below and PRODUCT_ID, TDC_NO, REVISION values in “tdcProduct1” table whose structure I designed below.how to pass those array list of values from server side to database and how to store further in database.

<script type="text/javascript">
    $(document).on("click", "[id*=btnFrmSubmit]", function () {  
        var user = {};
        user.PRODUCT_ID = 1;
        user.TDC_NO = $("[id*=Tdc_No]").val();
        user.REVISION = $("#Revision").text();
        /* Creating Array object as WireDimDetails to add in user object*/
        var WireDimDetails = new Array();
        $("#WireDimTbl tbody tr").each(function () {
            var row = $(this);
            /* Declare and sets the WireDimDetail object with the property which will add in WireDimDetails array object*/
            var WireDimDetail = {};
            var sizeMin = row.find("[id^=SizeMin]").val();
            /* Checking if control exist or not else assign empty value in sizeMax*/
            var sizeMax = row.find("[id^=SizeMax]") != "undefined" ? row.find("[id^=SizeMax]").val() : "";
            var tolMin = row.find("[id^=TolMin]").val();
            var tolMax = row.find("[id^=TolMax]").val();
            /*Sets the Values of controls */
            WireDimDetail.SizeMin = sizeMin;
            WireDimDetail.SizeMax = sizeMax;
            WireDimDetail.TolMin = tolMin;
            WireDimDetail.TolMax = tolMax;
            /*Add WireDimDetail object in WireDimDetails Array object*/
            WireDimDetails.push(WireDimDetail);
        })
        /*Add WireDimDetails array of object to user object*/
        user.WireDimDetails = WireDimDetails;
        $.ajax({
            type: "POST",
            url: "TDC.aspx/SaveFrmDetails",
            data: JSON.stringify({ user: user, }),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (response) {
                alert("Data has been added successfully.");
                window.location.reload();
            },
            error: function (response) { alert(response.responseText); }
        });
</script>

Server side

[WebMethod]
public static void SaveFrmDetails(User user)
{
    string connectionString = ConfigurationManager.ConnectionStrings["conndbprodnew"].ConnectionString;
    using (OracleConnection con = new OracleConnection(connectionString))
    {
        using (OracleCommand cmd = new OracleCommand("INSERT INTO TDC_PRODUCT1(PRODUCT_ID,TDC_NO, REVISION) VALUES (:PRODUCT_ID,:TDC_NO,:REVISION )", con))
        {
            cmd.CommandType = CommandType.Text;
            List<WireDimDetail> wireDimDetails = user.WireDimDetails;
            for (int i = 0; i < wireDimDetails.Count; i++)
            {
                WireDimDetail wireDimDetail = wireDimDetails[i];
                string sizeMin = wireDimDetail.SizeMin;
                string sizeMax = !string.IsNullOrEmpty(wireDimDetail.SizeMax) ? wireDimDetail.SizeMax : "0"; // set default value
                string tolMin = wireDimDetail.TolMin;
                string tolMax = wireDimDetail.TolMax;
            }

            cmd.Parameters.AddWithValue(":PRODUCT_ID", user.PRODUCT_ID);
            cmd.Parameters.AddWithValue(":TDC_NO", user.TDC_NO);
            cmd.Parameters.AddWithValue(":REVISION", user.REVISION);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
}

Table structure For saving data and array list of data “tdcProduct1” table consist of three rows Productid|Tdc_no|Revision

second table “Prop_detail” Tdc_no|Tdc_property

My concern is how to store array of data in “Prop_detail” table at the same time while storing data in “tdcProduct1” using SaveFrmDetails.

Any idea would be appreciated.
