Get Connection String from Config file

When I was trying to access my connection string from class file using below code 

string con = ConfigurationSettings.ConnectionStrings["Conn"].ConnectionString;

I was getting below error.

'System.Configuration.ConfigurationSettings' does not contain a definition for 'ConnectionStrings'

After Google I came you with the solution below,

System.Configuration.ConfigurationSettings.AppSettings

is obsolete. You need to use different class called ConfigurationManager to access information from the configuration file. To Access connection string, your code would look like

string con = System.Configuration.ConfigurationManager.ConnectionStrings["Conn"].ConnectionString
