Dear All,

Hi, I want add some comments in my web.config file at runtime.
Means for example

original Web.config file is:

C#

<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>

Have a look at the WebConfigurationManager class[^]. This class in turn provides access to another class[^], Configuration which will allow you to work and edit config files.

Possible, Yes! But I would not suggest to do it at all.

Web.Config is a configuration file based on which your website is running. Allowing anyone(even admin) to edit/update config file would need a restart of your application pool which would be an issue if someone is connected to your app at the same time somewhere else. Further, adding a "comment" to config file does not sounds anywhere important or necessary feature.

If you think otherwise, just find/locate the config file, and find the node and update it just as a normal XML. Do make sure, you have permission to edit/update the file.
