Compiler Error C2585
Error Messageexplicit conversion to 'type' is ambiguous
The type conversion can produce more than one result.
To fix by checking the following possible causes
Converting from a class or structure type based on multiple inheritance. If the type inherits the same base class more than once, the conversion function or operator must use scope resolution (::) to specify which of the inherited classes to use in the conversion.
A conversion operator and a constructor have been defined making the same conversion.
