List.Add() thread safety

Question

I understand that in general a List is not thread safe, however is there anything wrong with simply adding items into a list if the threads never perform any other operation

Answer 1

As others already said, you can use concurrent collections from the System.Collections.Concurrent namespace. If you can use one of those, this is preferred.

But if you really want a list which is just synchronized, you could look at the SynchronizedCollection-Class in System.Collections.Generic.

Note that you had to include the System.ServiceModel assembly, which is also the reason why I don't like it so much. But sometimes I use it.
