Reading Regex and strings from app.config

Question

I am trying to read regex from app.config file

if I try to read strings it is working fine but, if I try to get the regex Pattern it is not accepting my pattern

Here my code is

<appSettings>
<add key="regex" value=@"^(?<TicketNum>\w{3}-\d+)\s+(?<Message>.+?)$"></add>
<add key="getString" value="siva"/>;
</appSettings>

Am I missed anything?

Answer 1

You need to escape < and > in your xml, try this:

<appSettings>
    <add key="regex" value="^(?&lt;TicketNum&gt;\w{3}-\d+)\s+(?&lt;Message&gt;.+?)$"/>
</appSettings>

Escaping XML Data. Here:

Also no need for the @ sign.
