Winfrom 简单的进度条小程序

使用Winform空间编写简单的进度条小程序：

         所需控件：Lable 标签  TextBox  文本框  progressBar  进度条控件  timer 定时器

          下面是源码及效果图：

 1  /// <summary>
 2         /// 进度条开始
 3         /// </summary>
 4         /// <param name="sender"></param>

13             progressBar1.Minimum = 0;
14             progressBar1.Maximum = Convert.ToInt32(txtLenght.Text);
