How to add a stringformat in app.config

[Spippo]

Hi,

I want to create a string with string.format, but the format must be editable.
Therefor i want to add the format in app.config and read it from the program and enter the correct values in it.

This is my app.config-file:

<?xml version="1.0" encoding="utf-16" ?>
<configuration>
  <appSettings>
    <!-- SimpleMailAddin settings -->
         <!-- MailSender, SMTPServer and MailBodyFormat are required -->
    <add key ="MailSender" value ="[e-mail]"/>
    <add key ="SMTPServer" value ="VMEXCH.mydomain.com"/>
         <!-- This is the foSystermatstring of the body of the message. Usable values : {0} = Event_ID  {1} = Event_Name  {2} = Event_StartDate  {3} = Event_EndDate  {4} = Event_Description -->
    <add key="MailBodyFormat" value="Event Reminder\n\nEvent       : {1} ({0})\nStartdate   : {2}\nEnddate     : {3}\n\n{4}"/>    
  </appSettings>
</configuration>
 

My code tries to fill in the string like this:

string body = System.Configuration.ConfigurationManager.AppSettings["MailBodyFormat"];
body = string.format(body, Event_ID, Event_Name, Event_StartDate, Event_EndDate, Event_Description);
 

If I run this code, my string "body" still is "Event Reminder\n\Event : {1} ...." and not {Event Reminder\n\nEvent : My event ..."

Any way to solve this?

Is it giving any error?
I did something like this it works fine

<appSettings>
<add key="MyConnectionString" value="Driver={SQL Server};Server=myServerAddress;Database=myDataBase ;Uid={0};Pwd={1};"/>
</appSettings>

string myConnectionString = string.Empty;

myConnectionString = ConfigurationManager.AppSettings["MyConnectionString"];

myConnectionString = string.Format(myConnectionString, myUserId, myPassword);

Hi,

Thanks for the quick reply.
It did work correctly, I made a mistake in my program.

I did have a problem with the newline '\n', this was just display as the text "\n" and not as a newline.
I solved this by replacing '\n' with {5} and set the sixth parameter as "\n".

Thanks
