Programmatically read the value from web.config file

Here is a situation where you need to keep a key value pair element in the web.config file and read them during the run time. I suggest, better keep key /value pair under <appSettings> element and read it programmatically .

<appSettings>
  <add key="LicenseKey" value="987jKouterhsk" />
</appSettings>

Assume , you have added a license key as above in the web.config file. You need the license key during run time. You can access the license key class named "ConfigurationManager".

write a property  called getLicenseKey and return the corresponding license key.

public string GetLicenseKey
{
   get{   return  ConfigurationManager.AppSettings["LicenseKey"]; }
}

Now the property GetLicenseKey will have the value 987jKouterhsk. Use this value as per your requirement.
