HTML PROGRESS 中显示百分比,在ProgressBar控件中显示进度百分比

实现效果：

知识运用：

ProgressBar控件的Value属性　　　　//控件的当前值

Maximum属性　　　　　　//ProgressBar正在使用的范围的上限

PerformStep方法　　//按照Step属性的数量增加任务栏的当前位置

public void PerformStep()

实现代码：

private void StartOrStop_Click(object sender, EventArgs e)

{

if (timer1.Enabled == false)

{

timer1.Enabled = true;

StartOrStop.Text = "停止";

}

else

{

timer1.Enabled = false;

StartOrStop.Text = "开始";

}

}

private void timer1_Tick(object sender, EventArgs e)

{

if (progressBar1.Value == progressBar1.Maximum)

{

progressBar1.Value = progressBar1.Minimum;

}

else

{

progressBar1.PerformStep();

}

int process = 100 *

(progressBar1.Value - progressBar1.Minimum)

/ (progressBar1.Maximum - progressBar1.Minimum);

label1.Text = process.ToString()+"%" ;

}
