问题描述
我想列出另一个控件中名称以btnOverlay"开头的所有控件.我不能使用 Controls.Find
,因为它需要完全匹配.我相信我可以为此使用 LINQ,但我对此不是很有经验.是否可以?我该怎么做?
I want to list all controls inside another control which have names starting with "btnOverlay". I can't use Controls.Find
, because it needs an exact match. I believe I can use LINQ for this, but I'm not very experienced on that. Is it possible? How can I do it?
我使用的是 .NET 4.0.

推荐答案
您可以通过以下方式使用 LINQ 搜索它们:
You could search for them with LINQ via:
var matches = control.Controls.Cast<Control>()
.Where(c => c.Name.StartsWith("btnOverlay"));
Cast
调用是必需的,因为 ControlCollection
没有实现 IEnumerable
,只有 IEnumerable
代码>.此外,这不会进行递归搜索,而只会直接搜索包含的控件.如果需要递归,您可能需要将其重构为 类似于这个答案的方法.
The Cast<T>
call is required, as ControlCollection
does not implement IEnumerable<T>
, only IEnumerable
. Also, this doesn't do a recursive search, but only searches the contained controls directly. If recursion is required, you'll likely need to refactor this into a method similar to this answer.
