System.AggregateException IndexOutOfRangeException索引超出了数组界限

System.AggregateException IndexOutOfRangeException索引超出了数组界限

C#多线程下标越界

            Task[] tasks = new Task[renwuShu];

            for (int i = 0; i < renwuShu; i++)
            {
                tasks[i] = new Task<DataSet>(() => dobidui(xzhdas[i], das[i], i));
                tasks[i].Start();
            }
 
            Task.WaitAll(tasks);

改下面这样，task未执行前for已经循环完毕了，i值为最大值rewuShu，task执行时导致越界了

            Task[] tasks = new Task[renwuShu];
 
            for (int i = 0; i < renwuShu; i++)
            {
                var curi=i;/////
                tasks[i] = new Task<DataSet>(() => dobidui(xzhdas[curi], das[curi], curi));
                tasks[i].Start();
            }
