This will get you all files with infrared in file name and with extension jpg

I think this may be what you look for. ref: MSDN

我想這可能就是你要找的東西。 ref：MSDN

public static string[] GetFiles(string path, string searchPattern, SearchOption searchOption)
{
    string[] searchPatterns = searchPattern.Split('|');
    List<string> files = new List<string>();
    foreach (string sp in searchPatterns)
        files.AddRange(System.IO.Directory.GetFiles(path, sp, searchOption));
    files.Sort();
    return files.ToArray();
}

Usage

用法

var wantedImgs = GetFiles(
    dirYouWant, "*infrared*.jpg|*infrared*.gif", 
    earchOption.TopDirectoryOnly);

maybe *infrared*.(jpg|gif) will work

也許*紅外*。（jpg | gif）會起作用
