推荐答案

有一种非常残酷的方法:使用一个库向MemoryStream写一个位图，然后使用另一个库读取它；此方法可双向使用.

如果您需要从System.Drawing转到System.Windows.Media，则解决方法是使用System.Windows.Interop.Imaging，

There is one pretty brutal way of doing it: write a bitmap to MemoryStream using one library and read it using another one; this method works in both directions.

If you needed to go from System.Drawing to System.Windows.Media, the solution would be in using System.Windows.Interop.Imaging, http://msdn.microsoft.com/en-us/library/system.windows.interop.imaging.aspx[^].

Unfortunately, you need to do your conversion in the opposite direction, so I don''t know other way then using the MemoryStream. Now, the code sample is already available on the page referenced by Abhinav, you simply did not recognize it. Go lower, find the sample code by the keyword "MemoryStream" and invert the direction of conversion.
