c# - 逐字字符串文字中的新行

Question

我有一个字符串如下:

string example = @"string str = ""forty-two"";
char pad = '*';

单行输出如下:

string str = "forty-two"; char pad = '*';

我需要如下输出:

string str = "forty-two"; 
char pad = '*';

如何在此逐字字符串文字中的“char pad”之前插入换行符

Answer 1

在逐字字符串文字中，除了两个双引号外，所有转义字符都逐字解释，因此如果您想要两行字符串，则必须手动将其写成两行:

string example = @"string str = ""forty-two"";
char pad = '*';";

Console.WriteLine(example); // string str = "forty-two";
                            // char pad = '*';

来自 msdn :

A string literal such as @"c:\Foo" is called a verbatim string literal. It basically means, "don't apply any interpretations to characters until the next quote character is reached". So, a verbatim string literal can contain backslashes (without them being doubled-up) and even line separators. To get a double-quote (") within a verbatim literal, you need to just double it, e.g. @"My name is ""Jon""" represents the string My name is "Jon". Verbatim string literals which contain line separators will also contain the white-space at the start of the line, so I tend not to use them in cases where the white-space matters. They're very handy for including XML or SQL in your source code though, and another typical use (which doesn't need line separators) is for specifying a file system path.

It's worth noting that it doesn't affect the string itself in any way: a string specified as a verbatim string literal is exactly the same as a string specified as a normal string literal with appropriate escaping. The debugger will sometimes choose to display a string as a verbatim string literal - this is solely for ease of viewing the string's contents without worrying about escaping.
