大约百分之一的用户在使用我们的应用程序时遇到突然崩溃。日志显示在下面的异常，我到目前为止看到的唯一共同点是，它们都有XP SP3。

我相信你现在已经想到了这一点，但是如果你还没有我们遇到同样的问题。这是GDI +中的一个错误，这可以作为一种解决方法。不幸的是，我不知道为什么但是由于这些问题，我更倾向于关注它是固定的，而不是为什么它被修复。 ;）

image = image.GetThumbnailImage(image.Width, image.Height, null, IntPtr.Zero);

显然，该调用会调整PixelFormat，并将图像放入imagelist使用DrawImage可以处理的格式。
