HTML code

对于一个进度条，无碍乎是最小最大值，以及当前值等一些重要的属性，至于方法，用得较多的是PerformStep()和PerformClick()之类的。代码如下：


        private void btnRun_Click(object sender, EventArgs e)
        {
            btnRun.Enabled = false;

            if (txtBoxTarget.Text.Equals(String.Empty) || txtBoxTimes.Text.Equals(String.Empty))
            {
                MessageBox.Show("请输入连接的URL和连接次数！", "提示",
