C# winform 程式進度條

控制條控制項： progressBar

不能按照你程式的進程自動變化，需認為計算，調整變化量

 private void progressBar1_Click(object sender, EventArgs e)
        {
                this.progressBar1.Maximum = 100;//設置進度條最大長度值
                this.progressBar1.Value = 0;//設置當前值
        }
     

  progressBar1.Invoke(new Action(() => { this.progressBar1.Value = 0; }));    //進度條初始化

 if (this.progressBar1.Value < 45)
      {
                    progressBar1.Invoke(new Action(() => { this.progressBar1.Value += 5; }));//改變進度條的值
        }

 progressBar1.Invoke(new Action(() => { this.progressBar1.Value = this.progressBar1.Maximum; }));  //進度條到達滿值
