按顺序中断分组排序的数字集合

Question

如何按顺序中断分组排序的数字集合？

例如：

List<int> someList = new List<int>{1,2,3,7,8,9} 

输出：

someDictionary[0].Key == 1; 
someDictionary[0].Value == 3; 

someDictionary[1].Key == 7; 
someDictionary[1].Value == 9;

如果我明白你正确地这样的事情可以做的伎俩

private static List<List<int>> splitBySeq(List<int> someList) 
    { 
     //Stores the result 
     List<List<int>> result = new List<List<int>>(); 

     //Stores the current sequence 
     List<int> currentLst = new List<int>(); 
     int? lastNumber = null; 

     //Iterate the items 
     for (int i = 0; i < someList.Count; i++) 
     { 
      //If the have a "break" in the sequence and this isnt the first item 
      if (lastNumber != null && someList[i] != lastNumber + 1) 
      { 
       result.Add(currentLst); 
       currentLst = new List<int>(); 
      } 

      currentLst.Add(someList[i]); 
      lastNumber = someList[i]; 
     } 

     if (currentLst.Count != 0) 
      result.Add(currentLst); 

     return result; 
    }
