能否用改成lambda表达式的形式？

[解决办法]

int[] myStage = {4,4,3,3,4,4,3,3};
const int pastDays = 10;
    int startDay =0;
    int stage?=myStage.Select((x,i)=>new {x,i})
  .Aggregate((x,y)=>
{
startDay+=x.x;
    return startDay>=pastDays?x:y;
}).i;
Console.WriteLine(stage);

            int[] myStage = { 4, 4, 1, 3, 4, 4, 3, 3 };
            const int pastDays = 10;
            int endDay = 0;

            int stage = Array.FindIndex(myStage, o =>
            {
                int startDay = endDay;
                endDay = startDay + o; 
 

                return (startDay < pastDays && pastDays <= endDay);
            });
