How to convert Dictionary values into array
.Net framework dictionary represents a collection of keys and values. Dictionary<TKey, TValue>.Values property
allow us to get a collection containing the values in the Dictionary<TKey, TValue>. this dictionary 'Values' property
exists in System.Collections.Generic namespace. the 'Values' property value type is System.Collections.Generic.Dictionary<TKey, TValue>.ValueCollection.
so the dictionary 'Values' property allow us to get a generic list (collection) of dictionary values. to convert dictionary values into array, we can convert this generic list by its built in method ToArray(). List<T>.ToArray() method allow us to copy the elements of the List<T> to a new array. finally the conversion process is Dictionary<TKey, TValue>.Values.ToArray().
the following asp.net c# example code demonstrate us how can we convert dictionary values to an array programmatically at run time in an asp.net application.
