问题描述
我想知道什么是最佳实践打破C＃源代码的长字符串。这是字符串
I am wondering what is the "best practice" to break long strings in C# source code. Is this string
"string1"+
"string2"+
"string3"
在编译过程中或在运行时连接起来？
concatenated during compiling or in run time?
推荐答案
这是在编译时完成。 ，这是完全等同于string1string2string3
It's done at compile time. That's exactly equivalent to "string1string2string3".
假设你有：
string x = "string1string2string3"
string y = "string1" + "string2" + "string3"
$ b $ ：b
编译器将实习使得x和y引用同一个对象上执行相应的
The compiler will perform appropriate interning such that x and y refer to the same objects.
编辑：有一个关于很多讨论StringBuilder的的答案和评论。许多开发人员似乎认为，字符串连接应的总是的用的StringBuilder 完成。这是一个overgeneralisation - 这是值得理解的。
There's a lot of talk about StringBuilder in the answers and comments. Many developers seem to believe that string concatenation should always be done with StringBuilder. That's an overgeneralisation - it's worth understanding why StringBuilder is good in some situations, and not in others.
