6.1 Implicit conversions
Visual Studio .NET 2003
The following conversions are classified as implicit conversions:
- Identity conversions
- Implicit numeric conversions
- Implicit enumeration conversions
- Implicit reference conversions
- Boxing conversions
- Implicit constant expression conversions
- User-defined implicit conversions
Implicit conversions can occur in a variety of situations, including function member invocations (Section 7.4.3), cast expressions (Section 7.6.6), and assignments (Section 7.13).
The pre-defined implicit conversions always succeed and never cause exceptions to be thrown. Properly designed user-defined implicit conversions should exhibit these characteristics as well.
