Just for curiosity/convenience: C# provides two cool conditional expression features I know of:
string trimmed = (input == null) ? null : input.Trim();
and
string trimmed = (input ?? "").Trim();
I miss another such expression for a situation I face very often:
If the input reference is null, then the output should be null. Otherwise, the output should be the outcome of accessing a method or property of the input object.
I have done exactly that in my first example, but (input == null) ? null : input.Trim()
is quite verbose and unreadable.
Is there another conditional expression for this case, or can I use the ??
operator elegantly?
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.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
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 ...
Something like Groovy's null-safe dereferencing operator?
string zipCode = customer?.Address?.ZipCode;
I gather that the C# team has looked at this and found that it's not as simple to design elegantly as one might expect... although I haven't heard about the details of the problems.
I don't believe there's any such thing in the language at the moment, I'm afraid... and I haven't heard of any plans for it, although that's not to say it won't happen at some point.
EDIT: It's now going to be part of C# 6, as the "null-conditional operator".
