设计时获取窗体中所有组件名称

If you are hosting windows forms designer and using DesignerSurface, all components on the form that are visible in design time are accessible through DesignerSurface.ComponentsContainer property:

for (int i = 0; i < surface.ComponentContainer.Components.Count; i++)
{
    Console.WriteLine((i + 1) + ". " + surface.ComponentContainer.Components[i].Site.Name + ": " +       surface.ComponentContainer.Components[i].GetType().FullName);
}

 

host.CreateComponent(typeof(Form));
Form frm1 = (Form)Activator.CreateInstance(frmType);   
Form frm2 = (Form)host.RootComponent;

//FieldInfo fi = frmType.GetField("components", BindingFlags.Instance | BindingFlags.NonPublic);
//Container cn = null;
//if (fi != null)
//  cn = (Container)fi.GetValue(frm1);

//if (cn != null)
//  foreach (Component cp in cn.Components)
//  {
//    host.Container.Add(cp);
//    ComponentDesigner componentDesigner1 = ((ComponentDesigner)host.GetDesigner(((IComponent)cp)));
//    if (componentDesigner1 != null)
//      componentDesigner1.InitializeExistingComponent(((IDictionary)null));

//  }


FieldInfo[] fis = frmType.GetFields( BindingFlags.Instance | BindingFlags.NonPublic);
foreach (FieldInfo f in fis)
{
  object o = f.GetValue(frm1);
  if (o is Control)
    continue;
  if (o is Component)
  {
    Component cp = (Component)o;
    host.Container.Add(cp);
    ComponentDesigner componentDesigner1 = ((ComponentDesigner)host.GetDesigner(((IComponent)cp)));
    if (componentDesigner1 != null)
      componentDesigner1.InitializeExistingComponent(((IDictionary)null));
  }
}

  

private void button1_Click(object sender, EventArgs e)
        {
            Type t = typeof(Form1);
            object frm = Activator.CreateInstance(t);
            FieldInfo field = t.GetField("components", BindingFlags.Instance | BindingFlags.NonPublic);
            if (field != null)
            {
                IContainer componentsContainer = field.GetValue(frm) as IContainer;
                if (componentsContainer != null)
                {
                    // access components ny name, by index, in a loop ...
                    for (int i = 0; i < componentsContainer.Components.Count; i++)
                    {
                        Console.WriteLine(i + ". component: " + componentsContainer.Components[i].GetType().FullName);
                    }
                    
                }
            }
        }
