We may require small or medium changes in our code to run it in different machines and differnt configurations, Recompailing and Regenerating .exe files / dlls are a not a good practice. So we are using configuration files or settings files. Web.config is an example of such type file in web application. In Winforms or Windows application we need to use App.Config to achive the goal.

Here is an example to store and retreive the value from App.Config

Initially add an App.Config file to your project then set the values like following within the < appSettings > < /appSettings > block


               < appSettings > 
		< add key="Name" value="Mathew Philip"/>  		< /appSettings >

In the code behind you should import the following namespace



using System.Configuration;

Then retreive the value from the App.Config by the following code


                    string name = Convert.ToString(ConfigurationSettings.
                        AppSettings["Name"])

So that you can simply edit the XML in the App.Config and change your values without reconstructing the Exe file or Dll file. You can encript and store the contents if you want more security.
