Use of Finalize/Dispose method in C#

Question

C# 2008

I have been working on this for a while now, and I am still confused about the use of finalize and dispose methods in code. My questions are below:

Answer 1

Using lambdas instead of IDisposable.

I have never been thrilled with the whole using/IDisposable idea. The problem is that it requires the caller to:

• know that they must use IDisposable
• remember to use 'using'.

My new preferred method is to use a factory method and a lambda instead

Imagine I want to do something with a SqlConnection (something that should be wrapped in a using). Classically you would do

using (Var conn = Factory.MakeConnection())
{
     conn.Query(....);
}

New way

Factory.DoWithConnection((conn)=>
{
    conn.Query(...);
}

In the first case the caller could simply not use the using syntax. IN the second case the user has no choice. There is no method that creates a SqlConnection object, the caller must invoke DoWithConnection.

DoWithConnection looks like this

void DoWithConnection(Action action)
{
   using (var conn = MakeConnection())
   {
       action(conn);
   }
}

MakeConnection is now private
