请教，button事件

for (int i = 1; i < 6; i++)
                {
                    Button pageBT = new Button();
                    pageBT.Name = i.ToString();
                    pageBT.Text = i.ToString();
                    pageBT.Width = 18;
                    pageBT.Height = 18;
                    pageBT.Cursor = Cursors.Hand;
                    pageBT.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
                    pageBT.FlatStyle = FlatStyle.Flat;
                    pageBT.FlatAppearance.BorderSize = 0;  
                    pageBT.Location = new Point(i * 18 +50, 50);
                    pageBT.Click += new System.EventHandler(this.page_Click);
                    this.Controls.Add(pageBT);
               }
private void page_Click(object sender, EventArgs e)
        {
            //这里 如何 实现 点击 动态添加的 button 后 获取 自己的txt值？
         }

如 上述动态 产生  1 2 3 4 动态的 button
然后 点击 1按钮 弹出 1  
     点击 2按钮 弹出 2
     点击 3按钮  弹出 3
