不确定是否有更优雅的解决方案,但这样的事情应该可以工作:
var dict = new Dictionary<int, List<Controller>>();
int x = 0;
while (x < controllerList.Count)
{
var newList = new List<Controller> { controllerList[x++] };
for (int y = 0; y < 2; y++) // execute twice
if (x < controllerList.Count)
newList.Add(controllerList[x++]);
dict.Add(dict.Count, newList);
}
为了使其更通用,您还可以创建newList
空白以开始,然后更改y < 2
为y < GROUP_SIZE
您GROUP_SIZE
想要的任何大小的组。甚至可以将其提取到扩展方法中:
public static Dictionary<int, List<T>> ToGroupedDictionary<T>
(this IList<T> pList, int pGroupSize)
{
var dict = new Dictionary<int, List<T>>();
int x = 0;
while (x < pList.Count)
{
var newList = new List<T>();
for (int y = 0; y < pGroupSize && x < pList.Count; y++, x++)
newList.Add(pList[x]);
dict.Add(dict.Count, newList);
}
return dict;
}
然后你可以这样做:
var groups = new[]
{
"Item1",
"Item2",
"Item3",
"Item4",
"Item5",
"Item6",
"Item7",
"Item8"
}.ToGroupedDictionary(3);
