更新Windows窗体中的进度条

Question

基本上我试图让我的进度条出现在不同的级别和颜色，这取决于返回的值，但是我的2个进度条总是看起来一样，即使它们在不同的价值。此外，颜色也不更新。

double DFuelLvl = client.GetTankAmounts("Diesel"); 
      double PFuelLvl = client.GetTankAmounts("Unleaded"); 

      if (DFuelLvl < 300) 
      { 
       DieselBar.Value = 10; 
       DieselBar.ForeColor = Color.Red; 
       DieselBar.Style = System.Windows.Forms.ProgressBarStyle.Continuous; 
      } 
      else if(DFuelLvl > 300 && DFuelLvl< 500) 
      { 
       DieselBar.Value = 35; 
       DieselBar.ForeColor = Color.Orange; 
       DieselBar.Style = System.Windows.Forms.ProgressBarStyle.Continuous; 
      } 
      else if (DFuelLvl > 500 && DFuelLvl < 850) 
      { 
       DieselBar.Value = 75; 
       DieselBar.ForeColor = Color.Green; 
       DieselBar.Style = System.Windows.Forms.ProgressBarStyle.Continuous; 
      } 
      else 
      { 
       DieselBar.Value = 100; 
       DieselBar.ForeColor = Color.Blue; 
       DieselBar.Style = System.Windows.Forms.ProgressBarStyle.Continuous; 
      } 

      if (PFuelLvl < 300) 
      { 
       Petrolbar.Value = 10; 
       Petrolbar.ForeColor = Color.Red; 
       Petrolbar.Style = System.Windows.Forms.ProgressBarStyle.Continuous; 
      } 
      else if (PFuelLvl > 300 && DFuelLvl < 500) 
      { 
       Petrolbar.Value = 35; 
       Petrolbar.ForeColor = Color.Orange; 
      } 
      else if (PFuelLvl > 500 && DFuelLvl < 850) 
      { 
       Petrolbar.Value = 75; 
       Petrolbar.ForeColor = Color.Green; 
      } 
      else 
      { 
       Petrolbar.Value = 100; 
       Petrolbar.ForeColor = Color.Blue; 
      }

禁用视觉样式并在颜色更改后更新布局就足够了。
