Hi, whats is the easiest way to make C# dictionary access thread safe? Preferablly just using lock(object) but any other ideas welcome!

Answer 1

Why don't you just use ConcurrentDictionary class?

Answer 2

It is better to not lock two readers. Look here How you can use ReaderWriterLock

Answer 3

In .NET 4 you have the ConcurrentDictionary class.

If you need to use an older version of .NET, and want to write it yourself:

• wrap a Dictionary as a private field in your class
• use a separate object lockObject
• take a lock on lockObject before any access to the dictionary

Answer 4

It was already discussed : HERE

Answer 5

Thanks for the ConcurrentDictionary class, i did not know about this in .NET 4.0

Thank you
