C# allows the pre-defined implicit and explicit conversions to be augmented by user-defined conversions. User-defined conversions are introduced by declaring conversion operators (17.9.3) in class and struct types.

In This Section:

• 13.4.1: Permitted user-defined conversions
• 13.4.2: Evaluation of user-defined conversions
• 13.4.3: User-defined implicit conversions
• 13.4.4: User-defined explicit conversions
