Visual Basic (Declaration)
<SerializableAttribute> _ Public MustInherit Class ReadOnlyDictionaryBase(Of TKey, TValue)

Visual C++
[SerializableAttribute] generic<typename TKey, typename TValue> public ref class ReadOnlyDictionaryBase abstract

Type Parameters

TKey

TValue

The type exposes the following members.

Protected Constructors

	Name	Description
	ReadOnlyDictionaryBase<(Of <TKey, TValue>)>ReadOnlyDictionaryBase<(Of <TKey, TValue>)>New

Public Methods

	Name	Description
	Contains	Overloaded.
	ContainsKey	Determines whether a given key is found in the dictionary.
	ConvertAll<(Of <TOutput>)>	Convert this collection of items by applying a delegate to each item in the collection. The resulting enumeration contains the result of applying converter to each item in this collection, in order. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	CopyTo	Copies all the items in the collection into an array. Implemented by using the enumerator returned from GetEnumerator to get all the items and copy them to the provided array. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	CountWhere	Counts the number of items in the collection that satisfy the condition defined by predicate. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Exists	Determines if the collection contains any item that satisfies the condition defined by predicate. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	FindAll	Enumerates the items in the collection that satisfy the condition defined by predicate. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ForEach	Performs the specified action on each item in this collection. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	GetEnumerator	Must be overridden to enumerate all the members of the collection. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	GetHashCode	Serves as a hash function for a particular type. GetHashCode()() is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Remove	Removes a key from the dictionary. Always throws an exception indicating that this method is not supported in a read-only dictionary.
	ToArray	Creates an array of the correct size, and copies all the items in the collection into the array, by calling CopyTo. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ToString	Shows the string representation of the dictionary. The string representation contains a list of the mappings in the dictionary. (Overrides ReadOnlyCollectionBase<(Of <KeyValuePair<(Of <TKey, TValue>)>>)>..::ToString()().)
	TrueForAll	Determines if all of the items in the collection satisfy the condition defined by predicate. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	TryGetValue	Determines if this dictionary contains a key equal to key. If so, the value associated with that key is returned through the value parameter. This method must be overridden in the derived class.

Protected Methods

	Name	Description
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)

Public Properties

	Name	Description
	Count	Must be overridden to provide the number of items in the collection. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	Item	The indexer of the dictionary. The set accessor throws an NotSupportedException stating the dictionary is read-only.
	Keys	Returns a collection of the keys in this dictionary.
	Values	Returns a collection of the values in this dictionary. The ordering of values in this collection is the same as that in the Keys collection.

Explicit Interface Implementations

	Name	Description
	ICollection<(Of <T>)>..::Add	(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ICollection<(Of <T>)>..::Clear	(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ICollection<(Of <T>)>..::IsReadOnly	(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ICollection<(Of <T>)>..::Remove	(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	IDictionary<(Of <TKey, TValue>)>..::Add
	ICollection..::CopyTo	Copies all the items in the collection into an array. Implemented by using the enumerator returned from GetEnumerator to get all the items and copy them to the provided array. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ICollection..::IsSynchronized	Indicates whether the collection is synchronized. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	ICollection..::SyncRoot	Indicates the synchronization object for this collection. (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
	IDictionary..::Add	Adds a key-value pair to the collection. Always throws an exception indicating that this method is not supported in a read-only dictionary.
	IDictionary..::Clear	Clears this dictionary. Always throws an exception indicating that this method is not supported in a read-only dictionary.
	IDictionary..::Contains	Determines if this dictionary contains a key equal to key. The dictionary is not changed. Calls the (overridden) ContainsKey method. If key is not of the correct TKey for the dictionary, false is returned.
	IDictionary..::GetEnumerator	Returns an enumerator that enumerates all the entries in the dictionary. Each entry is returned as a DictionaryEntry. The entries are enumerated in the same orders as the (overridden) GetEnumerator method.
	IDictionary..::IsFixedSize	Returns whether this dictionary is fixed size.
	IDictionary..::IsReadOnly	Returns if this dictionary is read-only.
	IDictionary..::Item	Gets the value associated with a given key. When getting a value, if this key is not found in the collection, then null is returned. If the key is not of the correct type for this dictionary, null is returned.
	IDictionary..::Keys	Returns a collection of all the keys in the dictionary. The values in this collection will be enumerated in the same order as the (overridden) GetEnumerator method.
	IDictionary..::Remove	Removes the key (and associated value) from the collection that is equal to the passed in key. Always throws an exception indicating that this method is not supported in a read-only dictionary.
	IDictionary..::Values	Returns a collection of all the values in the dictionary. The values in this collection will be enumerated in the same order as the (overridden) GetEnumerator method.
	IEnumerable..::GetEnumerator	Returns an enumerator that enumerates all the entries in the dictionary. Each entry is returned as a DictionaryEntry. The entries are enumerated in the same orders as the (overridden) GetEnumerator method.
