Are the database-related objects such as connection object, command object, datareader, dataadapter,... unmanaged resources?
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:
