How to quote \" (slash double-quote) in a string literal?
提问by Bali C
This is probably a really simple question but I can't seem to get my head around it. I need to have a string that contains \"without it seeing it as an escape character. I tried using @but it won't work. The only other way I thought of doing this would be to use \u0022but don't want to unless I can help it.
这可能是一个非常简单的问题，但我似乎无法理解它。我需要一个字符串，它包含\"但不将其视为转义字符。我尝试使用@但它不起作用。我想这样做的唯一另一种方法是使用，\u0022但除非我能帮上忙，否则我不想这样做。
Desired string - string s = "\"\""; // Obviously this doesn't work!
所需的字符串 - string s = "\"\""; // Obviously this doesn't work!
Desired console output - \"\"
所需的控制台输出 - \"\"
Hope this makes sense.
希望这是有道理的。
Thanks!
谢谢！

Try
尝试
string s = "\\"\\"";
You have to escape your backslashes too.
你也必须逃避你的反斜杠。

Use this string:
使用这个字符串：
string s = "\\"\\"";
回答by Mongus Pong
Console.WriteLine( "\\"\\"" );
Just put a \before each character that needs to be printed.
只需\在需要打印的每个字符之前放置一个。

I think you have to escape backslashes too... so something like "\\\"\\\""should work, I believe.
我认为你也必须逃避反斜杠......所以像这样的东西"\\\"\\\""应该可以工作，我相信。

In verbatim string literals (@"...") a "in the string value is encoded as "", which happens to also be the onlyescape sequence in verbatim strings.
在逐字字符串文字 ( @"...")"中，字符串值中的 a 被编码为""，这恰好也是逐字字符串中唯一的转义序列。
@"\""Happy coding!\""" // => \"Happy coding!\"
"\\"Happy coding!\\"" // => \"Happy coding!\"
Note that in the 2nd case (not a verbatim string literal), a \is required before the \andthe "to escape them and prevent their normal meanings.
请注意，在第二种情况下（不是逐字字符串文字）， a\需要在 the\和the之前对"它们进行转义并防止它们的正常含义。
See the C# string referencefor more details and examples.

String s = @"\""\""";
DblQuote characters will escape a second dblquote character
DblQuote 字符将转义第二个 dblquote 字符
Though for better readability I would go with:
虽然为了更好的可读性，我会选择：
const String DOUBLEQUOTE = """";
const String BACKSLASH = @"\";
String s = BACKSLASH + DOUBLEQUITE + BACKSLASH + DOUBLEQUOTE;
回答by Eric Andres
In a verbatim string (a string starting with @"") to escape double quotes you use double quotes, e.g. @"Please press ""Ok"".". If you want to do it with verbatim strings then you would do something like @"\"""(that's 3 double quotes on the end there).
在逐字字符串（以 开头的字符串@""）中，您可以使用双引号来转义双引号，例如@"Please press ""Ok"".". 如果你想用逐字字符串来做，那么你会做类似的事情@"\"""（最后有 3 个双引号）。
回答by Lynn Crumbling
You can use the literal, but you need to double-up quotes.
您可以使用文字，但需要双引号。
string s = @"\""\""";
回答by Smit Patel
You can do like this,
你可以这样做，
string s = "something'\\'";
Use a single '' rather then "" in string to do the same.
在字符串中使用单个 '' 而不是 "" 来做同样的事情。
