Determines if this dictionary contains the given key and all of the values associated with that key..

Determines if this dictionary contains a key-value pair equal to key and value. The dictionary is not changed. This method must be overridden in the derived class.

Determines whether a given key is found in the dictionary.

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.

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.

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.

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.

Counts the number of items in the collection that satisfy the condition defined by predicate.

Enumerate all the keys in the dictionary. This method must be overridden by a derived class.

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.

Determines if the collection contains any item that satisfies the condition defined by predicate.

Enumerates the items in the collection that satisfy the condition defined by predicate.

Performs the specified action on each item in this collection.

Enumerate all the keys in the dictionary, and for each key, the collection of values for that key.

Creates an array of the correct size, and copies all the items in the collection into the array, by calling CopyTo.

Shows the string representation of the dictionary. The string representation contains a list of the mappings in the dictionary.

Determines if all of the items in the collection satisfy the condition defined by predicate.

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.
