c#取項目名稱—–和—–根據表單上的控制項名稱取控制項

取項目名稱：

        static string AppName()
        {
            string fullstr = Assembly.GetExecutingAssembly().FullName;
            return fullstr.Substring(0, fullstr.IndexOf(","));
        }

 

根據表單上的控制項名稱取控制項

 

 

 

        public static Control GetControl(Control ctrl, string controlName)
        {
            Control tempControl = null;
            //if the input control's name equals the input controlName,return the control
            if (ctrl.Name == controlName)
            {
                tempControl = ctrl;
            }
            else if (ctrl.Controls.Count != 0)//if the ctrl is not suitable,get its sub controls
            {
                foreach (Control subCtrl in ctrl.Controls)
                {
                    Control tb = GetControl(subCtrl, controlName);
                    if (tb != null)
                    {
                        tempControl = tb;
                        break;
                    }
                }
            }
            return tempControl;
        }

例：引入代碼

比如表單上有N個Panel, 我想操作名稱為"panel2"的Panel控制項。

 

            Panel pa = (Panel)GetControl(this, "panel2");
            pa.Height = 100;
