c# - Convert dictionary to List<KeyValuePair>

Question

I know that its possible to convert a List of KeyValuePair into a Dictionary, but is there a quick way (besides looping through manually) to perform the vice versa operation?

This would be the manual way,

foreach (KeyValuePair<double,double> p in dict)
{
    list.Add(new KeyValuePair<double,double>(p.Key,p.Value));
}

Not really that bad but I was just curious.

Answer 1

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>>.
