从特定的文本格式中提取数字和文本

Question

I have a text similar to this:

Hello @[123456:Foo]

How to get '123456' and 'Foo' ?

My attempt:

@\[([\d+]):([\s+])\]

Answer 1

You may use

@\[(\d+):([^][]*)]

See the regex demo . The values you need are in Group 1 and 2.

Details

• @\\[ - a @[ substring
• (\\d+) - Capturing group 1: one or more digits
• : - a colon
• ([^][]*) - Capturing group 1: zero or more chars other than ] and [
• ] - a ] char.

C# demo:

var m = Regex.Match(str, @"@\[(\d+):([^][]*)]");
if (m.Success) 
{
    Console.WriteLine(m.Groups[1].Value);
    Console.WriteLine(m.Groups[2].Value);
}
