how to refer to web.config from external class library dll?

[Stimp]

I've created a dll that I placed in my web application's 'bin'
directory.

I want to access the web.config file from this dll so that I can
retrieve a node value.

e.g.

Dim oDoc As XmlDocument = New XmlDocument

oDoc.Load("../web.config")

sOutput = oDoc.SelectSingleNode("//constring").Value


but it searches for the file in the system32 folder (or windows folder
in this case)

How can I get it to retrieve the file that is in the subdirectory?

thanks.

unfortunately I can't seem to use Server.Mappath with the dll...

Hi Stimp,

If you need to read some of the settings in web.config you can use

string value = ConfigurationManager.AppSettings[key]; // for appsettings
values
string value = ConfigurationManager.ConnectionStrings[key]; // for
connection strings

This works for all code running in the web application, including external
libraries.
For further info on how to read web.config check out the
System.Configuration namespace.

Indeed.

If you are using the .NET 1.1 Framework

connstr=ConfigurationSettings.AppSettings["constring"] will do the job.

Include System.Web in your dll and try using HttpContext.Current.Server.Mappath
