C# winform 程序进度条

控制条控件： progressBar

不能按照你程序的进程自动变化，需认为计算，调整变化量

 private void progressBar1_Click(object sender, EventArgs e)
        {
                this.progressBar1.Maximum = 100;//设置进度条最大长度值
                this.progressBar1.Value = 0;//设置当前值
        }
     

  progressBar1.Invoke(new Action(() => { this.progressBar1.Value = 0; }));    //进度条初始化

 if (this.progressBar1.Value < 45)
      {
                    progressBar1.Invoke(new Action(() => { this.progressBar1.Value += 5; }));//改变进度条的值
        }

 progressBar1.Invoke(new Action(() => { this.progressBar1.Value = this.progressBar1.Maximum; }));  //进度条到达满值
