哪些 C# 语言功能可以帮助您减少代码行并提高可读性？
我今天遇到了 ReSharper 提供的 C# 语言功能，ReSharper 是 ??操作员。这使得代码比我最初的尝试更加简洁。请参阅下面的迭代来改进代码的行数/长度/可读性。
第一次尝试可能类似于..
if (usersEmail == null)
userName = firstName;
else
userName = usersEmail;
重构为..
userName = usersEmail == null ? firstName : usersEmail;
最初我认为上面将是最有效/简洁的版本，但是还有第三步...
userName = usersEmail ?? firstName;
我想知道您是否有任何类似的示例，其中 C# 语言功能有助于减少代码行数并提高可读性？
I came across a C# language feature today courtesy of ReSharper, the ?? operator. This helped make the code even more concise than my initial attempt. See below for iteration in improving lines/length/readability of code.
A first attempt could be something like..
if (usersEmail == null)
userName = firstName;
else
userName = usersEmail;
Refactored to..
userName = usersEmail == null ? firstName : usersEmail;
Initially I thought the above would be the most efficient/concise version, but there is a third step...
userName = usersEmail ?? firstName;
Id like to know if you have any similar examples where C# language features help with reducing lines of code and improving readability?

using 块、LINQ、匿名委托，这样的例子不胜枚举。C

the using block, LINQ, anonymous delegates, the list would just go on..
C# has a very nice habit of introducing features in every major release that cut down the amount of code that you have to write.
用于隐式静态类型和自动属性的 var 关键字是两个很好的例子。
