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
