c# - C#如何在列表的开头和结尾处修剪空元素

Question

给定一个对象列表，其值是

StatusList = new List<StatusData>
                {
                    new StatusData {Count = 0, Id = 1},
                    new StatusData {Count = 0, Id = 2},
                    new StatusData {Count = 1, Id = 3},
                    new StatusData {Count = 0, Id = 4},
                    new StatusData {Count = 2, Id = 5},
                    new StatusData {Count = 3, Id = 6},
                    new StatusData {Count = 0, Id = 7},
                    new StatusData {Count = 0, Id = 8},
                    new StatusData {Count = 0, Id = 2}
                };

如何通过删除带有零的元素来修剪列表的左侧和右侧？

Answer 1

int start = 0, end = StatusList.Count - 1;

while (start < end && StatusList[start].Count == 0) start++;
while (end >= start && StatusList[end].Count == 0) end--;

return StatusList.Skip(start).Take(end - start + 1);
