找到当前项目中的所有窗体的控件

 List<Form> names = new List<Form>();
            List<string> GridList = new List<string>();
            foreach (var type in this.GetType().Assembly.GetTypes())
            {
                if (typeof(Form).IsAssignableFrom(type))
                {
                    try
                    {
                        using (Form form = Activator.CreateInstance(type) as Form)
                        {
                            names.Add(form); //names.Add(form.name)
                        }

                    }
                }
            }

            foreach (Form item in names)
