Reading a key from the Web Config using ConfigurationManager

Question

I need to read keys from web.config file. Here's what I write

string userName = System.Configuration.ConfigurationManager.AppSettings["PFUserName"];
string password = System.Configuration.ConfigurationManager.AppSettings["PFPassWord"];

And this is the appSettings in the Web.config:

<configuration>
   ....
   <appSettings>
      <add key="PFUserName" value="myusername"/>
      <add key="PFPassWord" value="mypassword"/>
   </appSettings>
   ....
</configuration>

When I debug the code, the username and password are both null, indicating that the keys are not being read.

What am I doing wrong when it comes to reading these numbers?

Instead of any other thing, use the WebConfigurationManager class. Consider the following scenario:

string userName = WebConfigurationManager.AppSettings["PFUserName"]
