Question

I have created a settings class where I added some parameters that are shown in the app.config below.

I want to access the connectionStrings and the usersettings inside my class but my attempts are not successful.

I’ve tried for example :

ConfigurationManager.ConnectionStrings['Alerter.AlerterSettings.ConnectionString']

But it doesnt work.

Here is the app.config:

<connectionStrings>
    <add name="Alerter.AlerterSettings.ConnectionString"     connectionString="DefaultEndpointsProtocol=https;sometext" />
</connectionStrings>
<userSettings>
    <Alerter.AlerterSettings>
        <setting name="TableName" serializeAs="String">
            <value>table5</value>
        </setting>
        <setting name="EmailUser" serializeAs="String">
            <value>user</value>
        </setting>
        <setting name="EmailPass" serializeAs="String">
            <value>pass</value>
        </setting>
    </Alerter.AlerterSettings>
</userSettings>

Don’t use ' – it is that character delimiter in C#, not a string delimiter:

ConfigurationManager.ConnectionStrings["Alerter.AlerterSettings.ConnectionString"]

You will also need to access the ConnectionString property of thee returned value:

string theConnectionString = 
            ConfigurationManager.ConnectionStrings["whatever"].ConnectionString;

Note on naming:

Alerter.AlerterSettings.ConnectionString is rather verbose – it is not very readable in my opinion, and this is not needed for a configuration option – in particular as it is in the connectionStrings section. AlerterSettings to my eyes is much more appropriate.
