使用基本表单生成器构建用于C＃管理的面板列表

Question

I'm working in a form builder that allows me to input select custom code. I'm trying to build a rudimentary window manager that shows and hide's panels. I'm using .Visible and System.Drawing.Point in this form OnClick:

public void togglePanel(Panel panel)
{
    if(panel.Visible) 
    {
        panel.Visible = false;
    }
    else 
    {
        panel.Visible = true;
        panel.Position = new System.Drawing.Point(panel1.Right + 5, panel1.Top);
    }
}

Currently closeAllPanels is just a long list of declarations, ie panel2.Visible = false;

How can I generate a list of these panels? Can I do so using the GetMembers() method? I'm new to C#, so I'm not really sure which class I'd need to run GetMembers() on to generate that list.

Or is there a much easier way that I'm completely missing?

Answer 1

If all of the Panels will always be in the same container, then do something like:

        List<Panel> Panels = new List<Panel>(this.Controls.OfType<Panel>());
        Console.WriteLine("# of Panels: " + Panels.Count.ToString());
        foreach(Panel pnl in Panels)
        {
            Console.WriteLine(pnl.Name + ": Visible = " + pnl.Visible.ToString());
        } 

You can replace "this" with the name of the container if the Panels are not directly contained by the Form itself.

To get a reference to a Panel "by name" with Controls.Find():

        string panelName = "panel1";
        Control[] matches = this.Controls.Find(panelName, true);
        if (matches.Length > 0 && matches[0] is Panel)
        {
            Panel pnl = (Panel)matches[0];
            // ... do something with "pnl" ...
        }
