    Does connectionString exist in the configuration file?

    Check whether

    1. You have a key present in connection strings section

    2. check the key name whether it is equal to connectionString or is something else

    I believe that System.Configuration.ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString returning null value.

    Please check the key and value from the web.config file.
