The details are as follows:

Regular expressions achieve maximum matching by default, which is very undesirable in some cases, such as the following code:

# starting IndiaInventoryAPP.exe "~ ~ DisplayVariableValues" parameterGroup,mailRecipients,ModuleArgs "~ DisplayVariableValues" LogFolder "~ $binaryExitCode = 0~~$IndiaInventoryArgs ="-asWin32Console-S HKDRMSUAT3-D $DatabaseName-U $DatabaseUserName-P $DatabasePassword-L $LogFolder-MailRecipients $mailRecipients-T $today_yyyy-Z D:\ cs48516\ posIds.txt "~ ExecuteBinaryCommand ([ref] $binaryExitCode)" $applicationPath/IndiaInventoryAPP.exe "$IndiaInventoryArgs $true~

We want to match any text between # and ~, and the way to achieve minimum matching is to use (? I)

Here are the specific implementation methods:

String commentGrammer = @ "(? I)\ #. *? ~"; Regex commentRegex = new Regex (commentGrammer,RegexOptions.IgnoreCase | RegexOptions.Singleline); MatchCollection commentMC = commentRegex.Matches (input); foreach (Match match in commentMC) {int length = match.Length; int index = match.Index; richTextBox.Select (index, length); richTextBox.SelectionColor = Color.Green;} above is all the content of the article "how regular expressions achieve minimum matching".
