The ListDictionary class implements IDictionary using a singly linked list. It is recommended for collections that typically include fewer than 10 items.Following are the properties of ListDictionary class −Sr.NoProperty & Description1CountGets the number of key/value pairs contained in the ListDictionary.2IsFixedSizeGets a value indicating whether the ListDictionary has a fixed size.3IsReadOnlyGets a value indicating whether the ListDictionary is readonly.4IsSynchronizedGets a value indicating whether the ListDictionary is synchronized (thread safe).5Item[Object]Gets or sets the value associated with the specified.6KeysGets an ICollection containing the keys in the ListDictionary.7SyncRootGets an object that can be used to synchronize access to the ListDictionary.8ValuesGets an ICollection containing the ...
