Dictionary转换为list

Dictionary转换为list

一、创建List的时候，将Dictionary的Value值作为参数


Dictionary<int, Person> dic = new Dictionary<int, Person>();

List<Person> pList = new List<Person>(dic.Values);

二、用Dictionary对象自带的ToList方法


Dictionary<int, Person> dic = new Dictionary<int, Person>();

List<Person> pList=new List<Person>();
pList = dic.Values.ToList<Person>();

三、建立List，循环Dictionary逐个赋值


Dictionary<int, Person> dic = new Dictionary<int, Person>();

List<Person> pList=new List<Person>();
foreach (var item in dic)
...{
   pList.Add(item.Value);
}

四、创建List后，调用List.AddRange方法


Dictionary<int, Person> dic = new Dictionary<int, Person>();

List<Person> pList=new List<Person>();
pList.AddRange(dic.Values);

五、通过Linq查询，得到结果后调用ToList方法


Dictionary<int, Person> dic = new Dictionary<int, Person>();

List<Person> pList=new List<Person>();
pList = (from temp in dic select temp.Value).ToList();
