Dictionary<TKey, TValue>.ValueCollection Class

Represents the collection of values in a Dictionary<TKey, TValue>. This class cannot be inherited.

Namespace:  System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
public sealed class ValueCollection : ICollection<TValue>, 
	IEnumerable<TValue>, ICollection, IEnumerable

The Dictionary<TKey, TValue>.Values property returns an instance of this type, containing all the values in that Dictionary<TKey, TValue>. The order of the values in the Dictionary<TKey, TValue>.ValueCollection is unspecified, but it is the same order as the associated keys in the Dictionary<TKey, TValue>.KeyCollection returned by the Dictionary<TKey, TValue>.Keys property.

The Dictionary<TKey, TValue>.ValueCollection is not a static copy; instead, the Dictionary<TKey, TValue>.ValueCollection refers back to the values in the original Dictionary<TKey, TValue>. Therefore, changes to the Dictionary<TKey, TValue> continue to be reflected in the Dictionary<TKey, TValue>.ValueCollection.

Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

A Dictionary<TKey, TValue>.ValueCollection can support multiple readers concurrently, as long as the collection is not modified. Even so, enumerating through a collection is intrinsically not a thread-safe procedure. To guarantee thread safety during enumeration, you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
