In the first example of the log4net configuration manual the author uses typeof(MyApp)
to get the type of the containing class MyApp
. Is there a reason not to use this.GetType()
, performance-wise? Because it seems to me that this.GetType()
is much safer from potential copy-paste errors when copying into another class.
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.
C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C.
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 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 ...
typeof(Foo)
is a static type lookup; essentially it occurs at compile time, so you only get the explicitly named type.
GetType()
is a dynamic type lookup; it's a virtual method that gets called at runtime and will give you the exact type even if you are using polymorphism. So it's "slower", theoretically, but it's giving you something you can't get from typeof(T)
. If you need one or the other for your design, the speed isn't going to be a factor.
