c# - 在字符串中写入“\\”

Question

我想做类似的事情：

string s = "\\blabla";

当你写“\”时，这意味着只有一个'\'。如何编写字符串，以便实际上有 2 '\' 表示 "\" ？

Answer 1

This works without a problem:

string s = "//blabla";

If you mean the backslash instead, you can use a verbatim string literal (using the @ symbol to avoid processing escape symbols):

string s = @"\\blabla";

Alternatively you can escape the escape character itself:

string s = "\\\\blabla";

Answer 2

'/' is not the escape char, so you can simply write "//"

The escape char is '\' and, to use it properly, you can refer to the MSDN instructions.

Answer 3

Try this:

string s = @"\\blabla";

The '@' symbol treats whatever follows it as a verbatim string literal (ie: you won't need to worry about escape characters within the string).

Answer 4

I think you mean \ not /.

You could escape the \ with another backslash "\\\\" or you could use a string literal @"\\"

Answer 5

您可以在字符串之前使用 @ 以避免转义特殊字符。

@-quoting 的优点是不处理转义序列，方便编写
