Solution

  • The objects you refer to are part of the .NET framework, and are garbage-collectable. So in that sense they are managed resources.

    A better question would be, do these objects implement IDisposable? If they do, you can use the using keyword in C# to clean them up once they go out of scope, or call their dispose() method manually.

    An example of using the using keyword with SqlConnection and SqlDataAdapter objects is here:
