The simplest way is to use List(T).AddRange Method (IEnumerable(T)) (System.Collections.Generic)[^] . See:

C#

Dictionary<int, string> dict = new Dictionary<int, string>();
dict.Add(1, "A");
dict.Add(2, "B");
dict.Add(3, "C");
dict.Add(4, "D");
dict.Add(5, "E");

List<string> lst = new List<string>();
lst.AddRange(dict.Values); //here!

You can use Dictionary.ToList(TSource) Method (IEnumerable(TSource)) (System.Linq)[^] too to "convert" dictionary object into list:

C#

List<KeyValuePair<int, string>> lst = dict.ToList();

For values only:

List<string> lst = dict.Values.ToList();

For further details, pleas see:
List(T) Class (System.Collections.Generic)[^]
Dictionary(TKey, TValue) Class (System.Collections.Generic)[^]
KeyValuePair(TKey, TValue) Structure (System.Collections.Generic)[^]
