My line of code as following <add key="abc_connection" value="server=xyz;User ID=abc;Password=abc;database=abc;Connection Timeout=0"/> what line of code I should use for replacing my code connection above ? so that i can call the apps.config file instead of using the code connection repeatedly. Thanks in advance.
