![]() The GetAllValues returns all values regardless of keys they are paired with, these method will be useful in the future. The GetKey and Get methods return the requested key and array of associated with key values. public void Set( string name, params T values) Set range of values (previous values will be removed). public void Add(NameValueCollection collection) The InvalidateCachedArrays method will reset the caches and will be called every time the data changes. Private fields will contain the cached data in specified arrays. The Class Definitionįor the first time, define the class and its members that contain keys and values. The interfaces IDictionary, IEnumerable> were implemented in the class as additional usability. The NameValueCollection collection is based on NameObjectCollectionBase - the base class for a collection of associated string keys and object values that contains base methods to access the values. The need to store objects in a collection in the original type attracted me to write a generic form of NameValueCollection as an alternative to NameValueCollection. references to the original objects are not preserved.not all types support conversion to and from a string.So what if you want to store values of any type, not only string? Of course, you can convert the text to the desired type every time you get a value, but there are three significant limitations here: NameValueCollection assumes that strings are used as both keys and values. What makes this collection special, is that one key can contain several elements and that null is allowed as a key or as a value. Elements can be obtained both by index and by key. Built into mscorlib realization of NameValueCollection is a collection that is similar to a Dictionary but NameValueCollection can have duplicate keys while Dictionary cannot.
