Adds a key-value pair to the collection. The value part of the pair must be a collection of values to associate with the key. If values are already associated with the given key, the new values are added to the ones associated with that key.

Adds the given key-value pair to the underlying dictionary of this view. If key is not within the range of this view, an ArgumentException is thrown.

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.

Removes all the keys and values within this view from the underlying OrderedMultiDictionary.

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

Tests if the key-value pair is present in the part of the dictionary being viewed.

Tests if the key is present in the part of the dictionary being viewed.

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 the number of values associated with a given key.

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

Enumerate all the keys in the dictionary.

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.

Removes a set of values from a given key. If all values associated with a key are removed, then the key is removed also.

Removes the key (and associated value) from the underlying dictionary of this view. If no key in the view is equal to the passed key, the dictionary and view are unchanged.

Removes the key and value from the underlying dictionary of this view. that is equal to the passed in key. If no key in the view is equal to the passed key, or has the given value associated with it, the dictionary and view are unchanged.

Removes all the items in the collection that satisfy the condition defined by predicate.

Remove all of the keys (and any associated values) in a collection of keys. If a key is not present in the dictionary, nothing happens.

Removes a collection of values from the values associated with a key. If the last value is removed from a key, the key is removed also.

Replaces all values associated with key with the single value value.

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.

Creates a new View that has the same keys and values as this, in the reversed order.

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. 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.

Number of keys in this view.

Returns a collection of all of the values in the dictionary associated with key, or changes the set of values associated with key. If the key is not present in the dictionary, an ICollection enumerating no values is returned. The returned collection of values is read-write, and can be used to modify the collection of values associated with the key.

Gets a read-only collection all the keys in this dictionary.

Gets a read-only collection of all key-value pairs in the dictionary. If a key has multiple values associated with it, then a key-value pair is present for each value associated with the key.

Gets a read-only collection of all the values in the dictionary.
