关于 List 泛型集合的问题

//定义存储每个柱子上可移动标签的泛型集合 List<List<Label>> seleckedCanMoveLb = new List<List<Label>>(); for (int i = 0; i < 3; i++) { seleckedCanMoveLb[i] = new List<Label>(); } /* for (int i = 0; i < seleckedCanMoveLb[index].Count; i++) { seleckedCanMoveLb[index}[i] }*/ /* for (int i = 0; i < seleckedCanMoveLb[index].Count; i++) { seleckedCanMoveLb[index}[i] }*/
都不对,应该如何访问List集合中的元素?
