 
        Object must be initialized before operation can be performed. ---> System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x88982F0C
报错代码出处如下:
var bytes = File.ReadAllBytes(imageFile);
if (bytes == null || bytes.Length == 0)
{ return null; }
using (var ms = new MemoryStream(bytes))
{
var decoder = BitmapDecoder.Create(ms, BitmapCreateOptions.None, BitmapCacheOption.OnLoad);
return decoder.Frames.FirstOrDefault(); }
求高手指点~
using (var ms = new MemoryStream(bytes))
 {
 BitmapSource bitSrc = null;
 Bitmap img = new Bitmap(ms);
 var hBitmap = img.GetHbitmap();
try
 {
 bitSrc = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
 hBitmap,
 IntPtr.Zero,
 Int32Rect.Empty,
 BitmapSizeOptions.FromEmptyOptions());
 }
 catch (Win32Exception)
 {
 bitSrc = null;
 }
return bitSrc;
 }
