I have a ConcurrentDictionary object that I would like to set to a Dictionary object.
Casting between them is not allowed. So how do I do it?

ConcurrentDictionary was introduced in .NET 4.0 and is available in the System.Collections.Concurrent namespace. It is thread-safe and internally uses locking. It is useful in the case of a multi-threaded application. However, ConcurrentDictionary is slower than Dictionary.

Dictionary<int, string> dictionary = new Dictionary<int, string> (); dictionary.Add (1,"A"); dictionary.Add (2, "B"); ConcurrentDictionary<int,string> concurrentDictionary = new ConcurrentDictionary<int, string> (dictionary); can i set the LINQ statement to be a ConcurrentDictionary? No. You can not..
As you know, when we are working on real-time projects, then it is possibile to work on a multi-threaded application to add and get items from the dictionary. the result may be wrong because the Dictionary is not thread-safe. ConcurrentDictionary is, by default, thread-safe, which provides the correct result.
The ConcurrentDictionary<K,V> class implements the IDictionary<K,V> interface, which should be enough for most requirements. But if you really need a concrete Dictionary<K,V>...
var newDictionary = yourConcurrentDictionary.ToDictionary(kvp => kvp.Key, kvp => kvp.Value, yourConcurrentDictionary.Comparer); // or... // substitute your actual key and value types in place of TKey and TValue var newDictionary = new Dictionary<TKey, TValue>(yourConcurrentDictionary, yourConcurrentDictionary.Comparer); If you love us?
