[WinForm]FindControl

关键代码：

        /// <summary>

        /// 按名称查找控件

        /// </summary>

        /// <param name="parentControl">查找控件的父容器控件</param>

        /// <param name="findCtrlName">查找控件名称</param>

        /// <returns>若没有查找到返回NULL</returns>

        public static Control FindControl(this Control parentControl, string findCtrlName)

        {

            Control _findedControl = null;

            if (!string.IsNullOrEmpty(findCtrlName) && parentControl != null)

            {

                foreach (Control ctrl in parentControl.Controls)

                {

                    if (ctrl.Name.Equals(findCtrlName))

                    {

                        _findedControl = ctrl;

                        break;

                    }

                }

            }

            return _findedControl;

        }

        /// <summary>

        /// 将Control转换某种控件类型

        /// </summary>

        /// <typeparam name="T">控件类型</typeparam>

        /// <param name="control">Control</param>

        /// <param name="result">转换结果</param>

        /// <returns>若成功则返回控件；若失败则返回NULL</returns>

        public static T Cast<T>(this Control control, out bool result) where T : Control

        {

            result = false;

            T _castCtrl = null;

            if (control != null)

            {

                if (control is T)

                {

                    try

                    {

                        _castCtrl = control as T;

                        result = true;

                    }

                    catch (Exception ex)

                    {

                        Debug.WriteLine(string.Format("将Control转换某种控件类型异常，原因:{0}", ex.Message));

                        result = false;

                    }

                }

            }

            return _castCtrl;

        }

    }

测试代码：

            bool _sucess = false;

            CheckBox _finded = panel1.FindControl("checkBox1").Cast<CheckBox>(out _sucess);

            if (_sucess)

            {

                MessageBox.Show(_finded.Name);

            }

            else

            {

                MessageBox.Show("Not Finded.");

            }
