eg
I'd like to get below sentence last agree time like pic.
input:
Agree|AAA Agree 7/28 22:34,Agree|BBBB Agree 7/28 23:20,Agree|CCC Agree 7/29 07:41,Agree|JJJ Agree 7/29 07:45,Agree|DDD Agree 7/29 07:54,forward|EEE forward 7/29 07:54,forward|FFF forward 7/29 07:54,forward|GGG forward 7/29 07:54,forward|HHHH forward 7/29 07:54
expected output:
7/29 07:54
I've tried to use LINQ but i can only do it like the picture.
void Main()
{
var input = "Agree|AAA Agree 7/28 22:34,Agree|BBBB Agree 7/28 23:20,Agree|CCC Agree 7/29 07:41,Agree|JJJ Agree 7/29 07:45,Agree|DDD Agree 7/29 07:54,forward|EEE forward 7/29 07:54,forward|FFF forward 7/29 07:54,forward|GGG forward 7/29 07:54,forward|HHHH forward 7/29 07:54";
var output = input.Split('|')
.Where(_ => _.Contains("Agree")).Select((e, index) => new {e,index})
.OrderByDescending(_=>_.index)
.Take(1);
}
This regex would do the trick
Agree (\d{1,2}\/\d{1,2} \d{1,2}:\d{1,2})(?!.*Agree \d{1,2}\/\d{1,2} \d{1,2}:\d{1,2})
This means Agree \d{1,2}\/\d{1,2} \d{1,2}:\d{1,2}
not followed by any occurence of Agree \d{1,2}\/\d{1,2} \d{1,2}:\d{1,2}
Then you would do this to extract 7/29 07:54
into lastAgree
variable
string pattern = @"Agree (\d{1,2}\/\d{1,2} \d{1,2}:\d{1,2})(?!.*Agree \d{1,2}\/\d{1,2} \d{1,2}:\d{1,2})";
// Get your match using pattern
var match = Regex.Match(text, pattern);
// Groups[1] is (\d{1,2}\/\d{1,2} \d{1,2}:\d{1,2})
var lastAgree = match.Groups[1].Value;
