Зарегистрировать данные из HTML-таблицы на SQL Server

Question

Я использую Visual Studio 2017 с C #, у меня есть таблица HTML, и я хочу импортировать данные из SQL Server.

Код представляет собой таблицу HTML, в которую пользователь будет вводить только цифрыи в конце суммируется, затем при нажатии кнопки сохранения данные должны быть сохранены в таблице SQL Server.

<table id="tablaConsultaSocial"  class="table table-borderless table-responsive  table-hover " >
     <thead class=" p-3 mb-2 bg-primary text-white table-bordered  table-hover  " .bg-primary>
        <tr >
         <th class="text-center" scope="col"  colspan="7" >TIPO CONSULTA</th>
        <td  class="text-center  " rowspan="2"><p class="verticalText">CÓDIDO</p></td>
       <th scope="col"  class="text-center " colspan="4">CONSULTA SOCIAL</th>
