How Can I Eliminate Flickering in Windows Forms Controls Using Reflection?

Double buffer controls to eliminate flickering

Flashing controls will affect the user experience. To work around this problem, you can use the DoubleBuffered property for individual controls. However, because the DoubleBuffered property is protected, accessing and modifying it directly requires more complex methods.

Solution using reflection

A common solution involves leveraging reflection to access protected DoubleBuffered properties. This method bypasses access restrictions and allows you to set the property to true.

<code class="language-c#">public static void SetDoubleBuffered(System.Windows.Forms.Control c)
{
   // 远程桌面注意事项
   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); 
}</code>

This helper method checks if the user is running in a remote desktop session. If so, avoid enabling double buffering to prevent potential conflicts.
