WinFrom 进度条控件怎么用?

[zhaozhijun0207]

窗体上有个Button控件,
点击控件,就去执行一些操作,

操作完成后,进度条就满了.然后隐藏进度条控件

Progressbar1.value=0;
Progressbar1.maximize=100;
for(int =0;i<100;i++)
{
     Progressbar1.value=Progressbar1.value+1;
     Progressbar1.update();
}
Progressbar1.visible=false;

        private void button1_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < 100; i++)
            {
                this.progressBar1.Value = i;
                
            }

            Thread.Sleep(200); //以免太快没效果

            this.progressBar1.Visible = false;
        }

C# code


private void button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < 100; i++)
{
this.progressBar1.Value = i;

}

Thread.Sleep(200); //以免太快没效果

this.progressBar1.Visible = false;
}

正解,你最好多看看msdn

^_^ Thread.Sleep(200);应该放到for里面吧

2楼正解

[cymyren]

恩 4楼说的对 要把
Thread.Sleep(200);
放在 for循环里，效果就出来了。

using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;//加此命名空间

namespace WindowsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{

for (int i = 0; i < 100; i++)
{
this.progressBar1.Value = i;

Thread.Sleep(20); //设为20就可以了
}
this.progressBar1.Visible = false;

}


}
}
