C# – idiomatic code


I'd be interested in some before-and-after c# examples, some non-idiomatic vs idiomatic examples. Non-c# examples would be fine as well if they get the idea across. Thanks.

Idiomatic means following the conventions of the language. You want to find the easiest and most common ways of accomplishing a task rather than porting your knowledge from a different language.

non-idiomatic python using a loop with append:

mylist = [1, 2, 3, 4]
newlist = []
for i in mylist:
    newlist.append(i * 2)

idiomatic python using a list comprehension:

mylist = [1, 2, 3, 4]
newlist = [(i * 2) for i in mylist]
