我们可以使用反射来获得在受保护的DoubleBuffered属性，那么它可以被设置为真正

We can use reflection to get at the protected DoubleBuffered property, and then it can be set to true.

注意：您应该支付开发商税，而不是使用双缓冲在终端服务会话（如远程桌面）如该人在远程桌面运行这个辅助方法不会在双重缓冲开启。

Note: You should pay your developer taxes and not use double-buffering if the user is running in a terminal services session (e.g. Remote Desktop) This helper method will not turn on double buffering if the person is running in remote desktop.

public static void SetDoubleBuffered(System.Windows.Forms.Control c)
{
   //Taxes: Remote Desktop Connection and painting

   if (System.Windows.Forms.SystemInformation.TerminalServerSession)
      return;

   System.Reflection.PropertyInfo aProp = 
         typeof(System.Windows.Forms.Control).GetProperty(
               "DoubleBuffered", 
               System.Reflection.BindingFlags.NonPublic | 
               System.Reflection.BindingFlags.Instance);

   aProp.SetValue(c, true, null); 
}
