查找Windows窗体C＃组件（未控制） [英] Find components on a windows form c# (not controls)

问题描述

我知道如何查找和收集在一个Windows窗体中使用的所有控件的列表。
事情是这样的：

I know how to find and collect a list of all the controls used in a Windows Form. Something like this:

static public void FillControls(Control control, List<Control> AllControls)
{
    String controlName = "";
    controlName = control.Name;

    foreach (Control c in control.Controls)
    {
        controlName = c.Name;
        if ((control.Controls.Count > 0))
        {
            AllControls.Add(c);
            FillControls(c, AllControls);
        }
    }
}

不过这个功能不检索在诸如表单底部的非可视组件HelpProvider，ImageList中，TableAdapter的，数据集等。

However this function does not retrieve the non-visual components on the bottom of the form like the HelpProvider, ImageList, TableAdapters, DataSets, etc.

有没有办法让这些组件的名单？以及

Is there a way to get the list of these components as well?

编辑：

感谢@HighCore指着我使用系统.ComponentModel.Component而不是在一个类似的功能确实让我的清单与组件，例如将ImageList，帮助供应商和BindingSource的。
但是，我还是从这个名单错过的TableAdapter和数据集。我想，因为那些直接从object继承。

Thanks @HighCore for pointing me to use System.ComponentModel.Component instead in a similar function does get me a list with components such the ImageList, the Help Provider and the BindingSource. However, I still miss from this list the TableAdapters and the DataSets. I suppose because those inherit directly from Object.

请。不要参考我的旧帖子，显示了类似的功能，矿山，只有得到控制列表。

Please. Don't refer me to older posts which shows a similar function to mine and that only gets the list of the controls.

编辑：为什么投反对票？这个问题从来没有被回答过了！

Why the negative votes? This question has never been answered before!

推荐答案

令人惊讶，似乎要做到这一点是通过反射的唯一途径。

Surprisingly, it seems the only way to do this is via reflection.

private IEnumerable<Component> EnumerateComponents()
{
    return from field in GetType().GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
           where typeof (Component).IsAssignableFrom(field.FieldType)
           let component = (Component) field.GetValue(this)
           where component != null
           select component;
}
