Share AppSettings configuration between a service Web and an asp.net web application

[Oriane]

Hi there,
In a web service (A), I would like to read and modify a web site (B)
configuration file. My goal is only to modify the appSettings section.

In order to avoid mistakes, I would like not to have these settings in the
default web.config file but, say, in a "settings.config" file, located in
the webservice virtual directory.

On IIS6, my webservice A is a web application from the B web site. So, the A
source files are in a (virtual) subdirectory of the B source files
directory.

Does it seem possible ?
___________________________________________________________________________________________________
Now, for a start, I've tried to read the settings in the web.config file of
A:

<?xml version="1.0"?>
<Configuration>
<...>
<appSettings>
<add key="a" value="aaa"/>
</appSettings>
<connectionStrings>
<clear/>
<add name="Stibil" connectionString="Server=.\sql2008..."/>
</connectionStrings>

I use this code:

System.Configuration.Configuration rootWebConfig1 =
WebConfigurationManager.OpenWebConfiguration(null);
if (rootWebConfig1.AppSettings.Settings.Count > 0)
{
KeyValueConfigurationElement customSetting =
rootWebConfig1.AppSettings.Settings[param];
if (customSetting != null)
return customSetting.Value;
}
return "Nothing";

And the fact is that "rootWebConfig1.AppSettings.Settings.Count" returns
0...
However,
"rootWebConfig1.AppSettings.ConnectionStrings..ConnectionStrings.ConnectionStrings.Count"
is 1.

I can't see where is my mistake...

__________________________________________________________________________________________________
Now if I want to read a config file (in my web service or in my web site),
which is not the default "web.config" file, possibly located in a virtual
subdirectory, what parameter do I need in the "OpenWebConfiguration" method
?

Best regards

Hi Oriane,

From your description, you want to use code to open the Web.config file of
the IIS root site and modify the AppSettings section in it, correct?

Based on my research, the WebConfigurationManager class can only open
"web.config" file, so if you use your own custom config file, it will not
work with it. And to open the web.config file for the IIS root site, you
only need to supply the root site virutal path which is simply "/"

Here is a test function which open & modify web.config file in IIS site
root(from an ASP.NET application/virtual directory under the site root):

==================

public partial class ConfigTestPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnAddEntry_Click(object sender, EventArgs e)
{
Configuration config =
WebConfigurationManager.OpenWebConfiguration("/");
config.AppSettings.Settings.Add("Item_" + DateTime.Now.Ticks,
"Value_" + DateTime.Now.Ticks);
Response.Write("<br/>Physical path: " + config.FilePath);
config.Save(ConfigurationSaveMode.Modified);
}
}
=================

Sincerely,

Steven Cheng
