c# - Reason for Invalid Token message -


in following code receiving "invalid token" error message. following this tutorial not sure how fix this. 

 class convertbitmap     {         [system.runtime.interopservices.dllimport("gdi32.dll")]         public static extern bool deleteobject(intptr handle);         public static bitmapsource;         public static intptr intpointer;         public static bitmapsource bitmaptobitmapsource(system.drawing.bitmap bitmap)         {             intpointer = bitmap.gethbitmap();              bitmapsource = system.windows.interop.imaging.createbitmapsourcefromhbitmap(intpointer,                 intptr.zero,

the error happens @ end of line:

public static bitmapsource;
