问题描述

大家好，

即string jaggedArray[][] = new jaggedArray[200][]

Hello everybody ,
I have a jagged Array of size 200 , i.e., now i want to remove 154 row , how can i do that ???

i.e.,string jaggedArray[][] = new jaggedArray[200][]

推荐答案

将其设置为null.

Set it to null.

jaggedArray[154] = null;

如果您确实希望将其完全删除，则必须将每一项向下移动一个位置，然后将数组的大小调整为小一个.不过，如果这样做，我建议使用列表列表，而不是使用锯齿状数组，其用法基本相同.

If you actually want it to be completely removed, you would have to move every item after it down one position and resize the array to be one item smaller. If you do that, though, I recommend using a list of lists rather than a jagged array, which has basically the same usage.
