Type Parameters

TKey

The type exposes the following methods.

Public Methods

  NameDescription
Public methodContainsOverloaded.
Public methodContainsKey
Determines whether a given key is found in the dictionary.
Public methodConvertAll<(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>)>.)
Public methodCopyTo
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>)>.)
Public methodCountWhere
Counts the number of items in the collection that satisfy the condition defined by predicate.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodExists
Determines if the collection contains any item that satisfies the condition defined by predicate.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodFindAll
Enumerates the items in the collection that satisfy the condition defined by predicate.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodForEach
Performs the specified action on each item in this collection.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodGetEnumerator
Must be overridden to enumerate all the members of the collection.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodGetHashCode
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.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodRemove
Removes a key from the dictionary. Always throws an exception indicating that this method is not supported in a read-only dictionary.
Public methodToArray
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>)>.)
Public methodToString
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()().)
Public methodTrueForAll
Determines if all of the items in the collection satisfy the condition defined by predicate.
(Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Public methodTryGetValue
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

  NameDescription
Protected methodFinalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)

Explicit Interface Implementations

  NameDescription
Explicit interface implemetationPrivate methodICollection<(Of <T>)>..::Add (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Explicit interface implemetationPrivate methodICollection<(Of <T>)>..::Clear (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Explicit interface implemetationPrivate methodICollection<(Of <T>)>..::Remove (Inherited from ReadOnlyCollectionBase<(Of <T>)>.)
Explicit interface implemetationPrivate methodIDictionary<(Of <TKey, TValue>)>..::Add
Explicit interface implemetationPrivate methodICollection..::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>)>.)
Explicit interface implemetationPrivate methodIDictionary..::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.
Explicit interface implemetationPrivate methodIDictionary..::Clear
Clears this dictionary. Always throws an exception indicating that this method is not supported in a read-only dictionary.
Explicit interface implemetationPrivate methodIDictionary..::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.
Explicit interface implemetationPrivate methodIDictionary..::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.
Explicit interface implemetationPrivate methodIDictionary..::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.
Explicit interface implemetationPrivate methodIEnumerable..::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.
