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.
