Hi All,

I'm trying to retrieve a SQLServer connection string form my app.config file in my Windows Service project written in C# 4.

I've put at the top...
using System.Configuration;

then I try in my start event...

C#

protected override void OnStart(string[] args)
 {
     try
     {
         cStr = ConfigurationManager.AppSettings["ConnectionString"].ToString();


     }
     catch (Exception e)
     {
         File.AppendAllText(Environment.CurrentDirectory + "\\ServiceMessages.txt", "\r\nOn start Error - " + e.Message);
     }
 }

cStr is an instance string declared earlier.
But it wont compile and my intellisence highlights the ConfigurationManager word saying it doesn't exist in the current context.

What am I doing wrong here?
Thanks.

Have you tried defining the full namespace:

C#

cStr = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"].ToString();

or defining

C#

using System.Configuration;

You need to use the namespace System.Configuration and also have to add the reference to the assembly System.Configuration.dll

hope it helps :)
