如何从包含任何容器中的控件的表单中获取所有控件? [英] How can I get all controls from a Form Including controls in any container?

问题描述

例如，我需要一种方法来禁用表单中的所有按钮或验证所有文本框的数据.有任何想法吗?提前致谢！

I need, for example, a way to disable all buttons in a form or validate all textboxes' data. Any ideas? Thanks in advance!

推荐答案

最简单的选择可能是级联:

The simplest option may be to cascade:

public static void SetEnabled(Control control, bool enabled) {
    control.Enabled = enabled;
    foreach(Control child in control.Controls) {
        SetEnabled(child, enabled);
    }
}

或类似的；您当然可以传递一个委托以使其相当通用:

or similar; you could of course pass a delegate to make it fairly generic:

public static void ApplyAll(Control control, Action<Control> action) {
    action(control);
    foreach(Control child in control.Controls) {
        ApplyAll(child, action);
    }
}

然后是:

ApplyAll(this, c => c.Validate());

ApplyAll(this, c => {c.Enabled = false; });
