MultiValueDictionaryTKey, TValue Class |
Extension to the normal Dictionary. This class can store more than one value for every key. It keeps a HashSet for every Key value.
Calling Add with the same Key and multiple values will store each value under the same Key in the Dictionary. Obtaining the values
for a Key will return the HashSet with the Values of the Key. It can also merge with other instances of MultiValueDictionary, as long
as the TKey and TValue types are equal.

The MultiValueDictionaryTKey, TValue type exposes the following members.
Constructors| Name | Description | |
|---|---|---|

Initializes a new instance of the MultiValueDictionaryTKey, TValue class.
|
| MultiValueDictionaryTKey, TValue(IEqualityComparerTValue) |
Initializes a new instance of the MultiValueDictionaryTKey, TValue class.
|
 | MultiValueDictionaryTKey, TValue(SerializationInfo, StreamingContext) |
Initializes a new instance of the MultiValueDictionaryTKey, TValue class.
|
Properties| Name | Description | |
|---|---|---|
 | Comparer | Gets the IEqualityComparerT that is used to determine equality of keys for the dictionary. (Inherited from DictionaryTKey, HashSetTValue.) |
| Count | Gets the number of key/value pairs contained in the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
| Item | Gets or sets the value associated with the specified key. (Inherited from DictionaryTKey, HashSetTValue.) |
| Keys | Gets a collection containing the keys in the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
| Values | Gets a collection containing the values in the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
Methods| Name | Description | |
|---|---|---|
| Add(TKey, TValue) | Adds the specified key and value to the dictionary. (Inherited from DictionaryTKey, HashSetTValue.) |
| Add(TKey, TValue) |
Adds the specified value under the specified key
|
| AddRange |
Adds the range of values under the key specified.
|
| Clear | Removes all keys and values from the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
| ContainsKey | Determines whether the DictionaryTKey, TValue contains the specified key. (Inherited from DictionaryTKey, HashSetTValue.) |
| ContainsValue(TValue) | Determines whether the DictionaryTKey, TValue contains a specific value. (Inherited from DictionaryTKey, HashSetTValue.) |
| ContainsValue(TKey, TValue) |
Determines whether this dictionary contains the specified value for the specified key
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetEnumerator | Returns an enumerator that iterates through the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetObjectData |
Gets the object data.
(Overrides DictionaryTKey, TValueGetObjectData(SerializationInfo, StreamingContext).) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValues |
Gets the values for the key specified. This method is useful if you want to avoid an exception for key value retrieval and you can't use TryGetValue
(e.g. in lambdas)
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Merge |
Merges the specified multivaluedictionary into this instance.
|
| OnDeserialization | Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from DictionaryTKey, HashSetTValue.) |
| Remove(TKey) | Removes the value with the specified key from the DictionaryTKey, TValue. (Inherited from DictionaryTKey, HashSetTValue.) |
| Remove(TKey, TValue) |
Removes the specified value for the specified key. It will leave the key in the dictionary.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TryGetValue | Gets the value associated with the specified key. (Inherited from DictionaryTKey, HashSetTValue.) |
Explicit Interface Implementations| Name | Description | |

| ICollectionKeyValuePairTKey, TValueContains | Determines whether the ICollectionT contains a specific key and value. (Inherited from DictionaryTKey, HashSetTValue.) |
| IDictionaryContains | Determines whether the IDictionary contains an element with the specified key. (Inherited from DictionaryTKey, HashSetTValue.) |
| ICollectionKeyValuePairTKey, TValueCopyTo | Copies the elements of the ICollectionT to an array of type KeyValuePairTKey, TValue, starting at the specified array index. (Inherited from DictionaryTKey, HashSetTValue.) |
