Extract image tags from HTML in C#

February 25, 2010 C# Regular expressions Nils Snippet

A pretty little C# function that returns a list of strings containing all image tags extracted from a HTML string.

private List<string> GetImagesInHTMLString(string htmlString) {
    List<string> images = new List<string>();
    string pattern = @"<(img)\b[^>]*>";

    Regex rgx = new Regex(pattern, RegexOptions.IgnoreCase);
    MatchCollection matches = rgx.Matches(htmlString);
    
    for(int i=0, l=matches.Count; i<l; i++) {
        images.Add(matches[i].Value);
    }
    
    return images;
}
