The remove element removes a reference to an inherited sections or section groups. New sections and section groups can be added to the collection in the current configuration file by using the section and sectionGroup elements.

.
The following code example shows how to use the remove element in an application configuration file to remove a section that was previously defined in the Machine.config file.
The following Machine.config file code declares a section named sampleSection
.
<configuration>
<configSections>
<section name = "sampleSection"
type = "System.Configuration.SingleTagSectionHandler" />
</configSections>
<sampleSection setting1 = "Value1"
setting2 = "value two"
setting3 = "third value" />
</configuration>
The following example application configuration file removes the sampleSection
section. After removal, the application cannot retrieve the settings that are in sampleSection
. If a configuration file tries to use a configuration section after the handler reference is removed, ASP.NET issues the server error, "Unrecognized configuration section element_name"
.
<configuration>
<configSections>
<remove name = "sampleSection" />
</configSections>
</configuration>
