The following code sample removes the newly-added ADO.NET connection manager from the collection.

using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

            // Create an application and load the sample.
            Application app = new Application();

            // Show how many connections are in the package.
            int myConnsCount = myConns.Count;
            Console.WriteLine("The number of connections is: {0}", myConnsCount);

            Console.WriteLine("The number of connections is finally: {0}", myConnsCount);

            // Using the Contains method, verify if the connection is in the collection.
            Boolean connRemoved = myConns.Contains("My OLEDB ConnectionManager");
            Console.WriteLine("The connection is still in the collection? {0}", connRemoved);
            Console.WriteLine();
        }
    }
}
