Did you add a reference to the System.Configuration.dll file? If you do, ConfigurationManager becomes available and you should be able to get your connection string provided you have it set up in the App.config file.

Hi
Maybe you did not using System.Configuration namespace :

XML

 <configuration>
  <connectionstrings>
    <add name="DBConnectionString">
      connectionString="Data Source=Manoj;Initial Catalog=Test;Persist Security Info=True;User ID=sa;Password=admin123"
      providerName="System.Data.SqlClient" />
  </add></connectionstrings>
</configuration>

C#

using System.Configuration;

string nwConn = System.Configuration.ConfigurationManager.ConnectionStrings[1].ToString();

However you have many different solutions for reading connection string from app.config for example follow of these links:
Connection string App.Config
Connection Strings and Configuration Files
connection string and app config

Best Regards.
