Code in 1.1 That doesn't work in 2.0

Here is the code that gives me trouble:

Code:

---


        m_alFriends = ArrayList.Synchronized(new ArrayList(25));

---

I Declared m_alFriends like so:

Code:

---


        private List<Friends.Friend> m_alFriends;

---

I changed that from:

Code:

---


        private ArrayList m_alFriends;

---

I get the following error:

Code:

---


Error        7        Cannot implicitly convert type 'System.Collections.ArrayList' to 'System.Collections.Generic.List<Defiance.Bncs.Friends.Friend>'        C:\Documents and Settings\JoeL Zimmerman\My Documents\My Programming\C#\8.0\Defiance\Defiance.Connection\BNCS\OpenGameProtocol.cs        764        31        Defiance.Connections

The ArrayList and the Generic.List(Of T) are completely different types. You cannot create a synchronised ArrayList and assign it to a Generic.List(Of T) variable. You need to create a synchronised Generic.List(Of T). The Generic.List(Of T) type doesn't have a Synchronized method though, so I'm not sure if it's possible. You may have to use lock statements to manually synchronise access to your collection.
