why is " remove key="myAdminTool" / " added while adding key to webconfig

i used a snippet of code from internet it resulted in the next web.config appsettings . another snipped of code only added the setting

Sub config()
        Dim conf As Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")


        
        Dim myAdminKeyVal As KeyValueConfigurationElement
        myAdminKeyVal = New KeyValueConfigurationElement("myAdminTool", "admin.aspx")

        conf.AppSettings.Settings.Add(myAdminKeyVal)

        conf.Save(System.Configuration.ConfigurationSaveMode.Modified)


    End Sub


the web config:

 <appSettings>
    <remove key="myAdminTool" />
    <add key="myAdminTool" value="admin.aspx,admin.aspx,admin.aspx" />
    <add key="NewKey0" value="vrijdag 25 november 2011 11:26:43" />
    <add key="NewKey1" value="vrijdag 25 november 2011 11:26:50" />
    <add key="NewKey2" value="vrijdag 25 november 2011 11:30:30" />

back slash indicates end of that particular configuration, in your case each key.

i mean , i understand the code add the element < add key="myadmintool" etc / > but why also the eleement <remove key "admintools" />

is that to remove all other keys with the attribute "admintools" preceding this remove key ?

<remove key="myAdminTool" />

It will remove all the previouse values for the 'myAdmingTool" key before assigning the new values. Kind of a reset thing.
