Delphi字符串中的一个字符如何转义 [英] How does one escape characters in Delphi string

问题描述

Delphi 字符串使用单引号，例如 'a valid string'.如何在文字字符串中指定 ' 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

要为字符串添加单引号，请包含两个 ' 标记，例如

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

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

在上面的字符串中，你用普通的单引号开始一个字符串，然后用两个单引号开始.字符串的结尾也是如此.

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.

您也可以使用 # 后跟一个数字作为其他转义字符，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 

或者只是

str := 'Newline'#13#10

当然，换行使用依赖于平台的常量更好.

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