I was wondering if it is possible to add multiple generic constraints?
I have an Add method that takes an Object (Either Email, Phone or Address), so i was thinking something like:
public void Add<T>(T Obj) where T : Address where T : Email where T : Phone { if (Obj is Address) m_Address.Add(Obj as Address); else if (Obj is Email) m_Email.Add(Obj as Email); else m_Phone.Add(Obj as Phone); }
But I keep getting:
"A constraint clause has already been specified for type parameter 'T'. All of the constraints for a type parameter must be specified in a single where clause."
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr. Stroustroupe.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
C is more difficult to learn than JavaScript, but it's a valuable skill to have because most programming languages are actually implemented in C. This is because C is a “machine-level” language. So learning it will teach you how a computer works and will actually make learning new languages in the future easier.
You can't do that. Why not just have three methods and let the compiler do the hard work for you?
public void Add(Address address) { m_Address.Add(address); } public void Add(Email email) { m_Email.Add(email); } public void Add(Phone phone) { m_Phone.Add(phone); }
