两者都可以通过
KeyValuePair<TKey,TValue>
进行遍历,并且两者可以相互转换:
List<KeyValuePair<string,string>> list = new List<KeyValuePair<string, string>>();
list.Add(new KeyValuePair<string, string>("asdf1", "1"));
list.Add(new KeyValuePair<string, string>("asdf1", "1"));
list.Add(new KeyValuePair<string, string>("asdf1", "1"));
Dictionary<string, string> dictionary = list.ToDictionary(x => x.Key, x => x.Value);
list = dictionary.ToList();
> 但是,后者的Key是唯一的,序列中不能包含相同Key值,前者就没有这个要求了。
> 因此,在将前者转化为后者时,如果有相同的key值,就会报错。
> 此外,
> `Enumarable.ToDictionary<TSource, TKey, TElement>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector, Func<TSource, TElement> elementSelector, IEqualityComparer<TKey> comparer)`
考虑是否可以利用第三个参数做一些事情,有待验证
