The explicit enumeration conversions are:

• From sbyte , byte , short , ushort , int , uint , long , ulong , char , float , double , or decimal to any enum-type.
• From any enum-type to sbyte , byte , short , ushort , int , uint , long , ulong , char , float , double , or decimal .
• From any enum-type to any other enum-type.

An explicit enumeration conversion between two types is processed by treating any participating enum-type as the underlying type of that enum-type, and then performing an implicit or explicit numeric conversion between the resulting types. [Example: For example, given an enum-type E with and underlying type of int , a conversion from E to byte is processed as an explicit numeric conversion (13.2.1) from int to byte , and a conversion from byte to E is processed as an implicit numeric conversion (13.1.2) from byte to int . end example]
