按照不同节点优先级，分布不同任务算法

回到家里，看了一下第一个for内部的for完全是多余的，优化为：

 1             List<int> configs = new List<int> { 1, 2, 1 };
 2 
 3             List<int> items = new List<int> { 
 4                 1,2,3,
 5                 4,5,6,
 6                 7,8,9
 7             };
 8 
 9             int skipCount = 0;
10 
11             for (int i = 0; i < configs.Count - 1; i++)
12             {
13                 int count = (int)(((decimal)configs[i] / configs.Sum()) * items.Count);
14 
15                 List<int> tempItems = items.Skip(skipCount).Take(count).ToList();
16 
17                 Console.WriteLine("index:{0}-skip:{1}-take:{2}---------------------------", i, skipCount, count);
18                 foreach (var tempItem in tempItems)
19                 {
20                     Console.WriteLine(tempItem);
21                 }
22                 Console.WriteLine("------------------------------------------------------");
23 
24                 skipCount += count;
25             }
26 
27             List<int> lastestItems = items.Skip(skipCount).Take(items.Count - skipCount).ToList();
28             Console.WriteLine("index:{0}-skip:{1}-take:{2}---------------------------", configs.Count - 1, skipCount, items.Count - skipCount);
29             foreach (var lastestItem in lastestItems)
30             {
31                 Console.WriteLine(lastestItem);
32             }
33             Console.WriteLine("------------------------------------------------------");
34 
35             Console.ReadKey();

 

运行结果：
