Type Parameters
- TKey
- TValue
The type exposes the following methods.
Public Methods
| Name | Description | |
|---|---|---|
 | Add | Overloaded. |
| AddMany | Adds new values to be associated with a key. If duplicate values are permitted, this method always adds new key-value pairs to the dictionary. If duplicate values are not permitted, and key already has a value equal to one of values associated with it, then that value is replaced, and the number of values associate with key is unchanged. |
| AsReadOnly |
Provides a read-only view of this collection. The returned ICollection<T> provides
a view of the collection that prevents modifications to the collection. Use the method to provide
access to the collection without allowing changes. Since the returned object is just a view,
changes to the collection will be reflected in the view.
(Inherited from CollectionBase<(Of <T>)>.) |
| Clear |
Clears the dictionary. This method must be overridden in the derived class.
(Overrides CollectionBase<(Of <KeyValuePair<(Of <TKey, ICollection<(Of <TValue>)>>)>>)>..::Clear()().) |
| 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 CollectionBase<(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 CollectionBase<(Of <T>)>.) |
| CountWhere |
Counts the number of items in the collection that satisfy the condition
defined by predicate.
(Inherited from CollectionBase<(Of <T>)>.) |
| Equals | (Inherited from Object.) |
| Exists |
Determines if the collection contains any item that satisfies the condition
defined by predicate.
(Inherited from CollectionBase<(Of <T>)>.) |
| FindAll |
Enumerates the items in the collection that satisfy the condition defined
by predicate.
(Inherited from CollectionBase<(Of <T>)>.) |
| ForEach |
Performs the specified action on each item in this collection.
(Inherited from CollectionBase<(Of <T>)>.) |
| GetEnumerator |
Enumerate all the keys in the dictionary, and for each key, the collection of values for that key.
(Overrides CollectionBase<(Of <KeyValuePair<(Of <TKey, ICollection<(Of <TValue>)>>)>>)>..::GetEnumerator()().) |
| 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 | Overloaded. |
| RemoveAll |
Removes all the items in the collection that satisfy the condition
defined by predicate.
(Inherited from CollectionBase<(Of <T>)>.) |
| RemoveMany | Overloaded. |
| Replace |
Replaces all values associated with key with the single value value.
|
| ReplaceMany |
Replaces all values associated with key with a new collection
of values. If the collection does not permit duplicate values, and values has duplicate
items, then only the last of duplicates is added.
|
| ToArray |
Creates an array of the correct size, and copies all the items in the
collection into the array, by calling CopyTo.
(Inherited from CollectionBase<(Of <T>)>.) |
| ToString |
Shows the string representation of the dictionary. The string representation contains
a list of the mappings in the dictionary.
(Overrides CollectionBase<(Of <KeyValuePair<(Of <TKey, ICollection<(Of <TValue>)>>)>>)>..::ToString()().) |
| TrueForAll |
Determines if all of the items in the collection satisfy the condition
defined by predicate.
(Inherited from CollectionBase<(Of <T>)>.) |
Protected Methods
| Name | Description | |
|---|---|---|
 | CountAllValues |
Gets a total count of values in the collection. This default implementation
is slow; it enumerates all of the keys in the dictionary and calls CountValues on each.
A derived class may be able to supply a more efficient implementation.
|
| CountValues |
Gets a count of the number of values associated with a key. The
default implementation is slow; it enumerators all of the values
(using TryEnumerateValuesForKey) to count them. A derived class
may be able to supply a more efficient implementation.
|
| EnumerateKeys |
Enumerate all the keys in the dictionary. This method must be overridden by a derived
class.
|
| EqualValues |
If the derived class does not use the default comparison for values, this
methods should be overridden to compare two values for equality. This is
used for the correct implementation of ICollection.Contains on the Values
and KeyValuePairs collections.
|
| 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.) |
| TryEnumerateValuesForKey |
Enumerate all of the values associated with a given key. This method must be overridden
by the derived class. If the key exists and has values associated with it, an enumerator for those
values is returned throught values. If the key does not exist, false is returned.
|
Explicit Interface Implementations
| Name | Description | |
|---|---|---|
  | IDictionary<(Of <TKey, ICollection<(Of <TValue>)>>)>..::Add | |
| IDictionary<(Of <TKey, ICollection<(Of <TValue>)>>)>..::TryGetValue | |
| 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 CollectionBase<(Of <T>)>.) |
| IEnumerable..::GetEnumerator |
Provides an IEnumerator that can be used to iterate all the members of the
collection. This implementation uses the IEnumerator<T> that was overridden
by the derived classes to enumerate the members of the collection.
(Inherited from CollectionBase<(Of <T>)>.) |
