@对字符串和路径做了什么 [英] what does the @ do to strings and paths
问题描述
我看到许多c＃代码示例与字符串相关或在
文件路径中使用字符串，其中包含@符号。
例如
string path1 = @" mydir" ;;
string path2 = @" \ mydir" ;;
@ do做什么？
Peted
I see many c# code samples that relate to strings or using strings in
file paths, that have an @ sign.
eg
string path1 = @"mydir";
string path2 = @"\mydir";
what does the @ do ?

--- -------------
@ -quoted字符串文字以@开头，并附在双
引号中。
例如：
@早上好 //字符串文字
@ -quoting的优点是不处理转义序列，
这使得它易于编写，例如，一个完全限定的文件
名称：
@" c：\Docs \Source \ a.txt" //而不是c：\\Docs \\Source \\\.txt
要在@ -quoted字符串中包含双引号，请将其加倍：
@""" Ahoy！""船长叫道。 //啊！船长叫道。
>From MSDN
----------------
@-quoted string literals start with @ and are enclosed in double
quotation marks.
For example:
@"good morning" // a string literal
The advantage of @-quoting is that escape sequences are not processed,
which makes it easy to write, for example, a fully qualified file
name:
@"c:\Docs\Source\a.txt" // rather than "c:\\Docs\\Source\\a.txt"
To include a double quotation mark in an @-quoted string, double it:
@"""Ahoy!"" cried the captain." // "Ahoy!" cried the captain.

what does the @ do ?
它禁用反斜杠作为转义字符。没有@，第二个
目录名应该是
string path2 = \\mydir;
Ebbe
It disables the backslash as escape character. Without the @, the second
directory name should have been
string path2 = \\mydir;
