XP is truly getting long in the tooth. XP确实变得越来越长。 The one thing it is missing is version 1.10 of gdiplus.dll, the update to GDI+ that first shipped with Vista. 它缺少的一件事是gdiplus.dll的1.10版，这是对Vista首次发布的GDI +的更新。 Lots of fixes in that version, for one it now actually supports ImageFormat.Icon. 该版本中有很多修复，现在它实际上支持ImageFormat.Icon。
Your image data represents an .ico file. 您的图像数据代表.ico文件。 Use the Icon(Stream) constructor instead. 请改用Icon（Stream）构造函数。 You may still have a problem with the 24bpp icons, I have no way to check that anymore. 你可能仍然有24bpp图标的问题，我无法再检查。

byte[] data = new byte[0];
data = ms.ToArray();
