Compiler Error C2585

explicit conversion to 'type' is ambiguous

The type conversion can produce more than one result.

To fix by checking the following possible causes

  1. 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.

  2. A conversion operator and a constructor have been defined making the same conversion.
