Use of Configurationse ttings or XMLDocument class ????

[serge calderara]

Dear all,

I have define a configuration file for my application with
different section groups and settings belonging to each
individual group like as follow :

=============== =============== =============== ========
<?xml version="1.0" encoding="utf-8" ?>
<configuratio n>
<configSections >
<!-- Definition of the User Management section -->
<sectionGroup name="UserManag ement">
<section name="settings"

type="System.Co nfiguration.Nam eValueSectionHa ndler" />
</sectionGroup>

<!-- Definition of the Configuration Mangement
section -->
<sectionGroup name="Configura tionManagement" >
<section name="settings"

type="System.Co nfiguration.Nam eValueSectionHa ndler" />
<section name="database"

type="System.Co nfiguration.Nam eValueSectionHa ndler" />
</sectionGroup>

<!-- Definition of the Language Management section -->

</sectionGroup>

<!-- Definition of the HMI builder Management section --

<sectionGroup name="HMIBuilde r">
<section name="settings"

type="System.Co nfiguration.Nam eValueSectionHa ndler" />
</sectionGroup>
</configSections>

<!-- Definition of the User management assembly setting

UserMangement -->
<UserManagement >
<settings>
<add key="LastLoginN ame"
value="calderar a" />
<add key="RememberEn try" value="1" />
</settings>
</UserManagement>

<!-- Definition of the Configuration management

</ConfigurationMa nagement>

<!-- Definition of the Language management assembly setting

<add key="LogFilePat h" value="C:" />
</appSettings>
<!-- Definition of the tracing operation

should be trace based
on TraceLevel (none, info, warning,fatal, verbose =

Note that a value of 3 will trace also level 1 and
2 -->
<system.diagnos tics>
<switches>
<add name="Enabled" value="1" />
<add name="TraceSeve rity" value="1" />
</switches>
</system.diagnost ics>
</configuration>

What is the best way to access and return those different
settings ?
Should I go with ConfigurationSe ttings class or use of
XMLDocument class ?

If A request is send to retrive parameter for a group I
should be able to rertreve all entry at once even if it
has different section.

thanks for your comments

Hi Serge,

Go for the ConfigurationSe ttings class, e.g.

NameValueCollec tion userManagement;
userManagement = ConfigurationSe ttings.GetConfi g("UserManageme nt")
as NameValueCollec tion;

and dereference like this:

userManagement["LastLoginN ame"]...

I think this is easier than using the XMLDocument class.
If A request is send to retrive parameter for a group I
should be able to rertreve all entry at once even if it
has different section.

Through the collection above you can retrieve any value in that group.

Thanks for your answer,

I go with Configurationse tting class for the time beeing.
But then I have one question:

How to know if the request parameter is valid ?

Exaemple:
userManagement = ConfigurationSe ttings.GetConfi g("UserManageme nt")

I need first to be sure that the section "UserMangem ent is still present
and if not return an error
or by this :

userManagement["LastLoginN ame"]...

I need toi be sure first that LastLoginname is really present and if not
return an erro as well.

What is the way to identify that a section or group is present?

thanks for your answer

Well, you could check for a null and for extra safety use a try..catch
handler.
