Set it to a specific value. What do you mean with "delete"? Please
provide a simple sample of what you want to do.

这是不可能的，因为长度（=数组的大小是固定的。你要
必须将数组复制到一个新数组而不删除项目。或者，

使用arraylist或任何其他类型的集合。更多信息：

另一个选择是将数组中的项目复制到新位置

（覆盖要删除的项目），然后使用Redim Preserve更改

大小。 Redim Preserve还会创建一个新数组，但它可能是最简单的

解决方案。尽管如此，Redim Preserve只能改变

最高等级的大小。

This is not possible because the length (= size) of an array is fixed. You''d
have to copy the array to a new array without the item to be removed. Or,
use an arraylist or any other sort of collection. More info:

Another option is to copy the items within the array to the new position
(overwriting the item to be removed), then use Redim Preserve to change the
size. Redim Preserve also creates a new array, but it might be the simplest
solution. Nevertheless, Redim Preserve can only change the size of the
highest rank.

嗨休，


如果2d数组是数据表或者是一个arraylist，而不是很容易的


使用remove，removeat with arraylist（或Ilist的其他实现

数组）

>
使用delete，deleteat，remove，removeat with the datatable


我希望这有帮助吗？

Hi Hugh,

If the 2d array is a datatable or an arraylist, than it is easy possible

using remove, removeat with arraylist (or other implementations of Ilist
arrays)

using delete,deleteat,remove, removeat with the datatable

I hope this helps?
