--------------030开发者_如何学Go805090908050805080502--
And I need to get with Regex in C# 2 parts:
- between the first and the second occurence of the string
"--------------030805090908050805080502"
- between the strings
"--------------030805090908050805080502"
and"--------------030805090908050805080502--"
I tried this regex:
--------------030805090908050805080502(\r.*)*--------------030805090908050805080502
but in C# regex.Matches(...)
returns only "--------------030805090908050805080502"
.
MatchCollection matches = Regex.Matches( text, @"([-]+\d{24})
(?<Content>.*?)
(?=\1)",
RegexOptions.IgnorePatternWhitespace |
RegexOptions.Singleline );
foreach ( Match match in matches )
{
Console.WriteLine(
string.Format( "match: {0}\n\n",
match.Groups[ "Content" ].Value ) );
}
Update: This expression will find all matches that come between two occurrences of a number. If the number needs to be a specific one, rather than any 24-digit number, change "\d{24}" to the number you want to match.
Have you tried a Split:
var str = stringToParse.Split(
new[] { "--------------030805090908050805080502" },
StringSplitOptions.None);
Console.WriteLine(str[1]);
