控制集合 [英] Control collection

问题描述

嗨


我可以通过它的索引访问表单上的特定控件，例如me.Controls.Item（0）.Name


如何通过名称访问控件，例如me.Controls.Item（QUOT; Label1的"）名称。可能吗？


谢谢


Ian

解决方案

Ian，

我不认为这是直接可能的，但是，我可能在这里被证明是错的。问题是IndexOf和Contains方法都需要将控件传递给它们。


但是，如果你想这样做，你可以创建一个列表，其中索引号是控件集合中的索引，这样你就可以通过名字来引用它。


我很想知道你是否找到了其他方法！


问候 - OHM

这是不可能的，但你可以将所有控件添加到a ''Hashtable''

（（name = key，value = reference）对）然后通过哈希表访问控件

。

Hi

I can access a particular control on a form by it''s index e.g. me.Controls.Item(0).Name

How would I access the control by name e.g. me.Controls.Item("Label1").Name. Is it possible?

Thanks

Ian

解决方案

Ian,
I Dont think this is directly possible, however, I might be proved wrong here. The problem is that the IndexOf and Contains methods both require a control to be passed to them.

However, if you wanted to do this, you could create a list, where the index number was the index in the controls collection, this way you could refer to it by name.

I would be interested to know if you do find a way other than that !

That''s not possible, but you can add all controls to a ''Hashtable''
((name = key, value = reference) pairs) and then access the controls
through the hashtable.
