Visual Studio可以使用正则表达式在替换操作中删除空行.

Visual Studio has ability to delete empty lines in replace operation using regular expressions.

• 单击 Ctrl - H (快速替换)

勾选使用正则表达式"

Tick "Use Regular Expressions"

在查找"中指定^$\n

在替换"框中删除所有内容.

In Replace box delete everything.

单击全部替换"

所有空行将被删除.

空行的正则表达式由

第^

行尾$

换行符\n

请注意，通常在Windows中，由2个字符表示的行尾 crlf -回车符(CR，ASCII 13，\r)换行符(LF，ASCII 10，\n).

Note that normally in Windows an end of line indicated by 2 characters crlf - Carriage Return (CR, ASCII 13, \r) Line Feed (LF, ASCII 10, \n).

一个正则表达式，用于删除确实不是空白的空白行(即它们没有空格):^:b*$\n

A regex to remove blank lines that are/aren't really blank (i.e. they do/don't have spaces): ^:b*$\n

要删除双行:^:b*\n:b*\n替换为:\n

To remove double lines: ^:b*\n:b*\n replace with: \n

*对于Visual Studio 2013及更高版本:*

^\s*$\n

，对于双行:

^(?([^\r\n])\s)*\r?\n(?([^\r\n])\s)*\r?\n
