准备工作

其实我也不知道这个应该叫什么名字，暂且叫有后退的窗体吧，这个窗体继承子基类窗体FrmBase，如果你对FrmBase还不了解，请移步 （十七）c#Winform自定义控件-基类窗体 查看

开始

添加一个Form，命名FrmBack，继承自FrmBase

属性

  private string _frmTitle = "自定义窗体";
         /// <summary>
         /// 窗体标题
         /// </summary>
         [Description("窗体标题"), Category("自定义")]
         public string FrmTitle
         {
             get { return _frmTitle; }
             set
             {
                 _frmTitle = value;
                 btnBack1.BtnText = value;
             }
         }
         [Description("帮助按钮点击事件"), Category("自定义")]
         public event EventHandler BtnHelpClick;

一点小事件

  private void btnBack1_btnClick(object sender, EventArgs e)
         {
             this.Close();
         }

         private void label1_MouseDown(object sender, MouseEventArgs e)
         {
             if (BtnHelpClick != null)
                 BtnHelpClick(sender, e);
         }
