如何在Delphi字符串中转义字符 [英] How does one escape characters in Delphi string

问题描述

Delphi字符串使用单引号，例如有效的字符串。如何指定文字字符串中的字符？如何引用空字节（Unicode代码点U + 0000）？

Delphi strings use single quotes, for example 'a valid string'. How does one specify the ' character within a literal string? How would one refer to the null byte (Unicode code point U+0000)?

推荐答案

要将一个单引号添加到字符串，您包括2'

To add a single quote to a string you include 2 ' marks e.g.

str := '''test string''';
Writeln(str)

在上面的字符串中，您有正常的单引号启动一个字符串然后两个为单引号。字符串的结尾也是一样。

In the string above, you have the normal single quotation to start a string and then two for the single quote. Same goes for the end of the string.

您还可以使用＃后跟一个数字用于其他转义字符，例如

对于新行：

You can also use # followed by a number for other escape character e.g.
For a new line:

str := 'Newline' + #13 + #10 

或只是

str := 'Newline'#13#10

当然，使用平台依赖的常规为换行更好。

Of course, using the platform-dependent constant for newline is better.
