我有来自文本文件的以下文字：
This is a Test, Section test TS 544 Ord 0 (1246788-5) [2]
This is a Test2, Section test TS 544 Ord 675 (1246788) [3]
This is a Tes3 (345678)
This is a Test 5 TS 544 Ord 12345
This is a Tes3 (PQ345678)
This is a Test9 TS 544 Ord XP (A567843)
This is a test8 TS 344 Ord Z [9]
我想在圆括号中提取数字并将其放在变量中，所以我想要这个：
Var a1 = The number within the round brackets so for e.g 1246788-5 or 345678 or PQ345678 or A567843
Var a2= I also want number in square brackets 2 or 3 or 9
Var a3 = I want to extarct all the numbers starting from TS and end at the next space so I need TS 544 ord 0, TS 544 Ord 675, TS 544 Ord 12345, TS 544 ORD XP
这些值来自文本文件。我可以使用正则表达式在C＃或Vb.net中提取这些值吗。
任何帮助将不胜感激
答案 0 :(得分：0)
(?<=\()([^)]*)(?=\))|(?<=\[)([^\]]*)(?=\])|(?<=TS\s)(\d+\s+\S+\s+\d+\b)
您可以使用此单一正则表达式。group 1将是您的var a1，依此类推。请参阅演示。
