我正在为我的 CAD 程序创建一个第三方插件,其中有一个子插件,它通过绘图并找到所有零件清单 (BOMS),如果零件清单中的任何项目在 BOM 之间共享 (1例如,用于 2 个焊件的零件)然后将第二个实例的项目编号更改为第一个实例的项目编号。它通过比较两个值之间的完整文件名来做到这一点。当他们匹配时,将数字更改为匹配者的数字。我已经让它工作了,但它运行有点慢,因为对于 100 个项目的 BOM,每个项目都与 100 个进行比较,因此这需要更长的时间(运行大约 60 秒)。考虑之后我意识到我不需要将每个项目与所有项目进行比较,我只需要比较直到找到重复项,然后退出搜索循环并转到下一个值。例如,项目 1 不需要与 99 个值的其余部分进行比较,因为即使它在位置 100 中有匹配项,我也不想将项目 1 的编号更改为项目 100 的编号。我想将项目 100 更改为1 个(即,将重复项更改为第一个遇到的重复项)。但是,对于我的代码,我无法退出循环比较,这给我带来了麻烦。麻烦的一个例子是这样的:
我有 3 个 BOM,每个 BOM 共享第 X 部分,在 BOM 1 中编号为 1,在 BOM 2 中编号为 4,在 BOM 3 中编号为 7。当我运行我的按钮时,因为一旦它我无法让它离开比较循环发现它首先匹配所有 X 部分,最终从 BOM 3 中获得项目编号 7,因为它是最后一个实例。 (我可以通过向后逐步执行我的 for 循环来让它做我想做的事情,因此一切都以最常见的方式结束,但我想让我的退出 fors 工作,因为它可以为我节省不必要的比较)
如何使用 if 条件打破嵌套的 for 循环?
这是我当前的代码:

要从嵌套的 for 循环中转义,您可以使用 GoTo
并指定 where。
Sub GoToTest()
Dim a, b, c As Integer
For a = 0 To 1000 Step 100
For b = 0 To 100 Step 10
For c = 0 To 10
Debug.Print vbTab & b + c
If b + c = 12 Then
GoTo nextValueForA
End If
Next
Next
nextValueForA:
Debug.Print a + b + c
Next
End Sub

以下是一些示例,用于演示 (1) 跳出(退出)循环和 (2) 在数组中查找值。
可以修改 2 个数组的交集示例以满足您的需求,即“创建一个比较循环来遍历绘图,根据其他 BOM 项目检查 oRefPart 并查看是否存在匹配。”请注意,您可能会在 2 个数组之间找到多个匹配项。
