各种形式的Foreach Every Control

Question

我想manipulate使用Controls form foreach loop foreach (Control c in this.Controls) { ComponentResourceManager resourceManager = new ComponentResourceManager(typeof(Main)); resourceManager.ApplyResources(c, c.Name, new CultureInfo(lang)); } ，我目前正在使用以下方法：

foreach

此Containers的问题在于Controls中的控件未包含在内。

如何在Containers中包含所有foreach？

我想在1个或2个{{1}}循环中执行此操作。

Answer 1

控件

将以下类添加到项目中：

public static class ControlExtensionMethods
{
    public static IEnumerable<Control> GetOffsprings(this Control @this)
    {
        foreach (Control child in @this.Controls)
        {
            yield return child;
            foreach (var offspring in GetOffsprings(child))
                yield return offspring;
        }
    }
}

它将返回调用者的所有子控件：

var offsprings = this.GetOffsprings();

您可以在循环中使用它：

foreach (Control c in this.GetOffsprings())
{
    // Do action
}

菜单项

将以下类添加到项目中：

public static class MenuStripExtensionMethods
{
    public static IEnumerable<ToolStripItem> GetSubItems(this ToolStrip @this)
    {
        foreach (ToolStripItem child in @this.Items)
        {
            yield return child;
            foreach (var offspring in child.GetSubItems())
                yield return offspring;
        }
    }

    public static IEnumerable<ToolStripItem> GetSubItems(this ToolStripItem @this)
    {
        if (!(@this is ToolStripDropDownItem))
            yield break;

        foreach (ToolStripItem child in ((ToolStripDropDownItem) @this).DropDownItems)
        {
            yield return child;
            foreach (var offspring in child.GetSubItems())
                yield return offspring;
        }
    }
}

它将返回调用者的所有子菜单项：

var allMenuItems = this.menuStrip1.GetSubItems()

Answer 2

让它递归：

private static void ApplyResources(ComponentResourceManager resourceManager,
                                   CultureInfo cultureInfo,
                                   Control container)
{
    foreach (var control in container.Controls)
    {
        resourceManager.ApplyResources(control, control.Name, cultureInfo);
        ApplyResources(resourceManager, cultureInfo, control);
    }
}

并像这样使用它：

var resourceManager = new ComponentResourceManager(typeof(Main));
var cultureInfo = new CultureInfo(lang);
ApplyResources(resourceManager, cultureInfo, this);
