Как добавить комментарий в файл web.config во время выполнения в asp.net

---

Дорогие Все,

Привет, я хочу добавить некоторые комментарии в свой файл web.config во время выполнения.
Значит например

оригинальный веб.файл конфигурации:

<pre lang="xml"><?xml version="1.0"?>
<!--
    Note: As an alternative to hand editing this file you can use the
    web admin tool to configure settings for your application. Use
    the Website->Asp.Net Configuration option in Visual Studio.
    A full list of settings and comments can be found in
    machine.config.comments usually located in
    \Windows\Microsoft.Net\Framework\v2.x\Config
-->
<configuration>
    <appSettings>
  <add key="customsetting1" value="Some text here" />
  <add key="myKey" value=",1,1,1,1,1,1" />
  <add key="RemoveTCPError" value="1,1" />
 </appSettings>
    <connectionStrings>
  <add name="myDatabaseName" connectionString="whatever" />
 </connectionStrings>
    <system.web>
        <!--
            Set compilation debug="true" to insert debugging
            symbols into the compiled page. Because this
            affects performance, set this value to true only
            during development.
        -->
        <compilation debug="true"/>
        <!--
            The <authentication> section enables configuration
            of the security authentication mode used by
            ASP.NET to identify an incoming user.
        -->
        <authentication mode="Windows"/>

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
            <error statusCode="403" redirect="NoAccess.htm" />
            <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>

    </system.web>
</configuration>

На какой-то кнопке нажмите,после того как она изменена, как :

<?xml version="1.0"?>

    <system.web>
        <!--

        <compilation debug="true"/>

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
            <error statusCode="403" redirect="NoAccess.htm" />
            <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>

    </system.web>
</configuration>

или в любом месте, где в файле web.config должны быть добавлены комм-сети или в любой комментируемой части должен быть добавлен текст.
Возможно ли это?
Пожалуйста,помогите мне.

Заранее всем спасибо.
