Find the index of a TabPage
提问by Bill Wohlers
I am using a For Each loop:
我正在使用 For Each 循环：
For Each tab As TabPage in TabControl1.TabPages
I cannot retrieve the index of tab. Is there a way to do this? I am trying to see if the index is below or above the current index.
我无法检索tab的索引。有没有办法做到这一点？我正在尝试查看该指数是低于还是高于当前指数。

There's also
还有
Dim indexOfTab As Integer = TabControl1.TabPages.IndexOfKey("TabName")
or
或者
Dim indexOfTab As Integer = TabControl1.TabPages.IndexOfKey(tab.Name)
This is useful if the tab page is ever removed from the collection but you want to know where it was. I know this sounds esoteric, but I've had that need quite a few times, and you can't get this information from the tab page object itself.
如果标签页曾经从集合中删除，但您想知道它在哪里，这将很有用。我知道这听起来很深奥，但我已经多次遇到这种情况，而且您无法从标签页对象本身获取此信息。
