How can I get ConnectionString Name from config file

I can read the connection strings from the config file, however I need to get the element name that is associated with connection string.

Example

<connectionStrings>
<add 
  name="LocalSqlServer" 
  connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=tr开发者_运维百科ue" 
  providerName="System.Data.SqlClient"   />
 </connectionStrings>

I need to get LocalSqlServer out of the connectionString.

According to the documentation it should work like this:

ConnectionStringSettingsCollection connections = ConfigurationManager.ConnectionStrings;

if (connections.Count != 0)
{
    foreach (ConnectionStringSettings connection in connections)
    {
        string name = connection.Name;
    }
}

Use

ConfigurationManager.ConnectionStrings[0].Name

You access it programmatically through the API.
