如何找到大括号内未包含的文本

Question

I have a text like test{0:##}test2{Order:C}test3 . I need to use regex and find the text test , test2 , test3 which are not inside the {...} .

For text inside the curly braces {0:##} i used

@"{0:(.*?)}"

But trying for text not inside the Curly braces, facing some difficulties.

Answer 1

If there are no nested braces you can use something like the following:

(?<=^|})[^{]+(?={|$)

This uses lookbehind and lookahead to find snippets embedded in }...{ or delimited by the start or end of the string on one end.

Quick PowerShell test:

PS> [regex]::Matches('test{0:##}test2{Order:C}test3', '(?<=^|})[^{}]+(?={|$)') | select Value

Value
-----
test
test2
test3

Answer 2

而不是匹配大括号之外的所有内容（如Joey所建议的），通过仅匹配大括号的表达式将字符串拆分为数组可能更容易。

result = Regex.Split(teststring, "\{[^}]*\}");

Answer 3

如果文本始终采用相同的格式，为什么不使用Split功能？
