I have managed to resolve this. See below.
StreamWriter sfw = new StreamWriter(@"W:\CTS Product\Mobile_Email_Updates\mob_email_" + DateTime.Today.ToString("ddMMyyyyhhmm") + ".txt", false);
DataTable dt = m_dtMobEmail;
foreach (DataRow dr in dt.Rows)
{
if (dr["Exported"].ToString() == "0")
{
sfw.WriteLine(dr["HolderRef"].ToString() + dr["DateConf"].ToString() + dr["MobileNum"].ToString().PadRight(20) +
dr["EmailAdd"].ToString().PadRight(80) + dr["Comms"].ToString() + dr["Confirmed"].ToString() + dr["Via"].ToString() +
dr["DateConf"].ToString());
}
}
sfw.Close();

I'd like to include a list of values in my app.config file that has no specific length.
I don't want to use "Setting 1" "Setting 2" etc. for obvious reasons.
I could define a type that wraps a List<string> for example and use this as the type for a custom section...
However this seems a little over the top. I am also dealing with a distributed system that has various components, and so I would like to avoid having to make that type available to in all of them.
Does anybody know a lightweight way of achieving this that is already part of the framework / System.Configuration namespace?
Thanks

I use a settings datatable based on an XML file, easy to maintain, easy to manage and you have complete control of it.

Hi,
Thanks for the suggestion.
Unfortuantely using a database is not really viable for this particular problem, as some of the components involved are deployed at customers' premises. I don't want to add the complexity of deploying a database engine etc.
Thanks,
Rob.

Ahhh...
I've just re-read your post. Properly this time 
Do you think it is possible to use a datatable as a Type for a custom config section?
The solution is quite committed to using app.config and System.Configuration. I wouldn't want to have to have a second xml file containing the serialised datatable - so I'd need to get it into app.config somehow...
Thanks again,
Rob.

LINQ to XML would work, and you could write/read your own file without worrying about messing up or dealing with multiple app.config files.
I'd probably create a class lib project that you can use in multiple assemblies. Shouldn't be too hard to come up with something usable and flexible.

Thanks for all your suggestions.
I have decided on the following:
Declare a section in app.config ilke this:
<section name="LogMessageReceiverConfig" type="RealTimeDelivery.Common.Logging.LogMessageReceiverConfigHandler, LogMessageReceiver"/>
The section then utilised like this:
<SecondaryIdentifiersSect>
<setting name="aaa" serializeAs="String">
<value>a1</value>
</setting>
<setting name="bbb" serializeAs="String">
<value>b1</value>
</setting>
<setting name="ccc" serializeAs="String">
<value>c1</value>
</setting>
</SecondaryIdentifiersSect>
and then accessed in code like this:
System.Configuration.ClientSettingsSection sect = (System.Configuration.ClientSettingsSection)System.Configuration.ConfigurationManager.GetSection("SecondaryIdentifiersSect");
foreach (System.Configuration.SettingElement e in sect.Settings)
{
System.Diagnostics.Debug.WriteLine(e.Name);
System.Diagnostics.Debug.WriteLine(e.Value.ValueXml.InnerText);
}

Is this HOmework? A little bit of effort won't kill you. Try first and see what you come up with. If you get stuc along the way then somebody here will be more than happy to help but people here don't take kindly to guys looking for somebody to do their homework for them.

NO THIS IS NOT a homework .i just need it for learning .

In which case you need the alternative site, rentacoder.com where people provide complete solutions - for a price 
The alternative is to do your own homework.

I am encrypting the web.config using RSA technique, and using aspnet_regiis command to do this. I successfully encrypted the <connectionstrings> and <appsettings> tags. However I got the following error while encrypting the <sessionstate> tag:-
The configuration section 'sessionState' was not found.
Failed!
The command that I used is:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regiis <br />
-pe "sessionState" -app "/LiveOne" -prov "LOProvider"
Kindly tell me a successful way to do this.

Encryption is used to encrypt sections - not individual tags. Why you would want to encrypt the sessionState tag is beyond me.

Hi,
can anyone tell me the c# way to get the log4net root logger?
background:
there's a dll wich executes any code specified via xml (dest. assembly path, dest. method, etc.). within this dll, log4net is correctly configured and works fine.
now i want to use the same logger from any of my dest. dlls. calling LogManager.GetRepository() and navigating through some public and private fields via visual studio tells that both appenders (configured in base dll) are available. But how to access them?

hello everybody,
i have a datatable wich i want it to be attached in an email as excel(.xls)
in order to do that:
1. i'm exporting the datatable into an excel file.
2. i'm saving it in a specific folder.
3. i'm attaching it.
is there any way to directly attach the datatable to an email as excel file directly without exporting and saving or at lest not saving because it's working on a server an i don't want to use its space
kind regards

Not that I can think of. An attachment has to be a physical file rather than an abstraction in memory, unless you write the data into the body of the email (rather a silly solution actually).
Why not clean up the attachment file after it has been sent? You could even clean out the attachment folder prior to sending the next email or have a job that periodically cleans the attachments, there are many options here.

Sorry to ask such a basic question, actually I'm new to C#.
I want to have a non-editable combo-box on my form (where user can choose from the items, but can not edit/type a new item into the combo. The .net 2005 forms editor gives me 2 choices (i) Create a list-box, which I don't want, as I need a drop-down (ii) Create a Combo-box, but that is always editable.
In VS6, we could create a combo and then in its properties we could choose the type to be list box, but I could not find any such property in C#. Any help is appreciated.
It's better to know some of the questions than all of the answers.
