system.configur ation net 2.0 - save

[Andrzej Kaczmarczyk]

Hello,

I am having troubles saving configuration file.

I did the folloing: inherited from ConfigurationSe ction,
ConfigurationCo llection, ConfigurationEl ement to define my own element in
config file.

If I do the following:

using System.Configur ation;

System.Configur ation.Configura tion configFile;
this.configFile =
ConfigurationMa nager.OpenExeCo nfiguration(Con figurationUserL evel.None);
DatabaseConnect ionSection dcs;
dcs = new DatabaseConnect ionSection();
DatabaseConnect ionSettings cn = new DatabaseConnect ionSettings();
cn.Name = "connectionName ";
dcs.Connections .Add(cn);
this.configFile .Sections.Add(D atabaseConnecti onSection.Name, dcs);
this.configFile .Save(Configura tionSaveMode.Fu ll);

everything works fine, I can save and load the settings on the next run.

Hoever I'd like to store the section in separate file.
So after dcs instantiation I did:
dcs.SectionInfo rmation.ConfigS ource = "DatabaseConnec tions.config";

on execution of the last line in above I get an exception "Object reference
not set to an instance of an object."
the config file has this file added:
<DatabaseConnec tions configSource="D atabaseConnecti ons.config" />

But the file itself isn't created and the application can't start on the
next run because of this.

I think, the problem is in the filePath or there is something else I need to
set in SectionInformat ion, but the docs aren't clear about that
