Question

My code is old code which uses ArrayList to store elements of collection. I use the m_objects.SyncRoot for locking purpose before delete the object:

        lock(m_objects.SyncRoot) 
        {
            m_objects.Remove(obj);

        }

The issue now is, I now want to change the type of m_objects from ArrayList to List<T>, and I encounter problem with the above code. What is the equivalent of List<T>‘s SyncRoot
?

I think this might be what you are looking for

List<string> list = new List<string>();
lock (((IList)list).SyncRoot)
{
}
