Gets the color depth of the image list.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When you set the color depth to a new value, the Handle for the image list is recreated. Because setting the property causes the handle to be recreated, you should set prior to setting the Images property. When the handle for the ImageList has been created, setting the or ImageSize properties in code, after setting the Images property, will cause the collection of images set for the Images property to be deleted.
