I checked the code from link Trying to save array of data in database using c#.

And mofofied the code as per the given table structure.

Refer the below code and implement it as per your code logic.

C#

[WebMethod]
public static void SaveFrmDetails(User user)
{
    string tdcProduct1Query = "INSERT INTO TDC_PRODUCT1(PRODUCT_ID,TDC_NO, REVISION) VALUES (@PRODUCT_ID,@TDC_NO,@REVISION)";
    SqlParameter[] tdcProduct1Parameters = new SqlParameter[]
    {
    new SqlParameter("@PRODUCT_ID", user.PRODUCT_ID),
    new SqlParameter("@TDC_NO", user.TDC_NO),
    new SqlParameter("@REVISION", user.REVISION)
    };
    // Insert record into tdcProduct1
    InsertRecords(tdcProduct1Query, tdcProduct1Parameters);

    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;
        InsertPropertyDetails(user, PropertyText.SizeMin, i + 1, wireDimDetail.SizeMin);
        if (!string.IsNullOrEmpty(wireDimDetail.SizeMax))
        {
            InsertPropertyDetails(user, PropertyText.SizeMax, i + 1, wireDimDetail.SizeMax);
        }
        InsertPropertyDetails(user, PropertyText.TolMin, i + 1, wireDimDetail.TolMin);
        InsertPropertyDetails(user, PropertyText.TolMax, i + 1, wireDimDetail.TolMax);
    }
}

private static void InsertPropertyDetails(User user, string propertyName, int rowNo, string tdcProperty)
{

    string propDetailQuery = "INSERT INTO Prop_detail(TDC_NO,RowNo,Prop_Name,Tdc_Property) VALUES (@TDC_NO,@RowNo,@Prop_Name,@Tdc_Property)";
    SqlParameter[] propDetailParameters = new SqlParameter[]
        {
        new SqlParameter("@TDC_NO", user.TDC_NO),
        new SqlParameter("@RowNo", rowNo),
        new SqlParameter("@Prop_Name", propertyName),

        };
    InsertRecords(propDetailQuery, propDetailParameters);
}

{
    string connectionString = ConfigurationManager.ConnectionStrings["dbpik"].ConnectionString;
    using (SqlConnection con = new SqlConnection(connectionString))
