>I never use that as all functions are mainly from the framework. So, if we change environment and do a framework for that, all the client code would remain as is for those functions in case ToUpper() wouldn't exist. But, at this point, it is difficult to try a few changes as it is only in the production that the problem started yesterday. That code as always worked well for a few years and still works well in our test servers.
If this is to extract the images - consider this
public static class MyClass
{
static string htmlSample = @"
<!DOCTYPE html>
<html lang=""en-GB"">
<head>
<meta charset=""utf-8"">
<title>Example of an inline image</title>
</head>
<body>
<img src=""balconyview.jpg"">
<Img Src = 'balconyview.jpg' alt='View from my balcony, showing a row of houses, trees and a castle'>
<img src='http://example.com/brokenlink/sunset.gif' alt='Beautiful Sunset' />
</body>
</html>
";
public static void Main()
{
IEnumerable<String> images = GetImages(htmlSample);
foreach (string image in images)
Console.WriteLine(image);
Console.ReadLine();
}
static IEnumerable<String> GetImages(string html)
{
List<string> images = new List<string>();
string pattern = @"\<img\s+src\s*=\s*((?<quote>[""'])(?<image>.*?)\k<quote>)";
MatchCollection matches = Regex.Matches(html, pattern, RegexOptions.IgnoreCase );
foreach (Match match in matches)
{
images.Add(match.Groups["image"].ToString());
}
return images;
}
}
