How i can use "/show_name=(.?)&show_name_exact=true\">(.?)
Match m = Regex.Match(input, "/show_name=(.*?)&show_name_exact=true\">(.*?)</i", RegexOptions.IgnoreCase);
// Check Match instance
if (m.Success)
{
// Get Group value
string key = m.Groups[1].Value;
Console.WriteLine(key);
// alternate-1
}
Error, Unterminated string literal(CS1039)] Error, Newline in constant(CS1010)]
What I am doing wrong?
I think you're mixing up .NET's regex syntax with PHP's. PHP requires you to use a regex delimiter in addition to the quotes that are required by the C# string literal. For instance, if you want to match "foo" case-insensitively in PHP you would use something like this:
'/foo/i'
...but C# doesn't require the extra regex delimiters, which means it doesn't support the /i style for adding match modifiers (that would have been redundant anyway, since you're also using the RegexOptions.IgnoreCase flag). I think this is what you're looking for:
@"show_name=(.*?)&show_name_exact=true"">(.*?)<"
Note also how I escaped the internal quotation mark using another quotation mark instead of a backslash. You have to do it that way whether you use the old-fashioned string literal syntax or C#'s verbatim strings with the leading '@' (which is highly recommended for writing regexes). That's why you were getting the unterminated string error.
