打破C＃源代码长串的最佳方法 [英] Best way to break long strings in C# source code

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 - 这是值得理解为什么的StringBuilder 在某些情况下取得良好，而不是在别人的。

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.
