Property Write Lock

Question

In my class, I have this property:

public List<MyObject> mCollection { get; set; }

This collection is used in some different streams.

What would I like to do to allow writing of this property only when all threads have finished reading mCollection.

Something like receiving and issuing a token and allowing recording only when all tokens are issued. Is there something similar in the framework?

Thanks in advance
