Keys. ToList(); List<string> values = keys. Select(i => dicNumber[i]). ToList();
KeyValuePair is the unit of data stored in a Hashtable (or Dictionary ). They are not equivalent to each other. A key value pair contains a single key and a single value. A dictionary or hashtable contains a mapping of many keys to their associated values.
To convert a Dictionary<TKey, TValue> to a List<KeyValuePair<TKey, TValue>> you can just say
var list = dictionary.ToList();
or the more verbose
var list = dictionary.ToList<KeyValuePair<TKey, TValue>>();
This is because Dictionary<TKey, TValue> implements IEnumerable<KeyValuePair<TKey, TValue>>.
Using linq:
myDict.ToList<KeyValuePair<double, double>>();
Dictionary elements are KeyValuePair items.
Like Jason said. But if you don't really need a list, then you can just cast it to an ICollection<TKey, TValue>; because it implements this interface, but some parts only explicitly. This method performs better because it don't copy the entire list, just reuses the same dictionary instance.
