How to programmaticaly change the web.config?

Hello group..

Is there a way to change web.config entries at runtime? I haven't
found a class for that.
I have around 20 entries in the web.config, and I want a add a
configuration menu into my app, so that the administrator can change
some of the settings, without editing the web.config directly with a
text editor.

In ASP.NET 2.0, you can use the System.Configuration classes, see
http://www.codeproject.com/KB/dotnet/mysteriesofconfiguratio n.aspx

You can also write to the web.config file in the same way as you would to
any XML file, something like (in VB.NET):
-----------------------------
Try
' Open web.config file
Dim doc As New XmlDocument()
doc.Load(Server.MapPath("web.config"))

Dim strSel As String
' Use an XPath query to look up the user element in this configuration
having
' a matching "name" attribute
strSel =
"/configuration/system.web/authentication/forms/credentials/ user[@name='" &
strUserName & "']"
Dim node As XmlNode = doc.SelectSingleNode(strSel)
' Modify the element
Dim element As XmlElement = CType(node,XmlElement)
element.SetAttribute("password",strHash)

' Save the configuration
doc.Save(Server.MapPath("web.config"))
Catch ex As Exception
Trace.Warn(ex.ToString())
End Try
------------------------------
Keep in mind that changing web.config may cause your application to restart,
thereby losing the session information for all users.

The way to go is to put all your setting that can change in a separate file.

Put this line in the section on web.config



Having done that, you can access parameteres in MySettings.xml via
ConfigurationManager.AppSettings.
