C# 特殊字符


字符串 - 特殊字符

因为字符串必须用引号括起来,所以 C# 会误解此字符串并生成错误。

string txt = "We are the so-called "Vikings" from the north.";

解决此问题的办法是使用 **反斜杠转义字符**。

反斜杠 (\) 转义字符将特殊字符转换为字符串字符。

转义字符 结果 描述
\' ' 单引号
\" " 双引号
\\ \ 反斜杠

序列 \"  在字符串中插入双引号。

示例

string txt = "We are the so-called \"Vikings\" from the north.";

自己试试 »

序列 \'  在字符串中插入单引号。

示例

string txt = "It\'s alright.";

自己试试 »

序列 \\  在字符串中插入单个反斜杠。

示例

string txt = "The character \\ is called backslash.";

自己试试 »
