Question

I am currently wanting to be able to cycle through a text file looking for a specific string, in my case: “mp4:production/

When the string has been matched (the file will be updated periodically – so the string won’t necessarily be present at first), its line (in the text file) can then be output e.g. in a messagebox

How could this be achieved, any examples would be appreciated

Answer 1

while(true) {
    Thread.Sleep(500); // lets get a break
    if(!System.IO.File.Exists(FILE_NAME)) continue;
    using (System.IO.StreamReader sr = System.IO.File.OpenText(FILE_NAME)) 
    {
        string s = "";
        while ((s = sr.ReadLine()) != null) 
        {
            if(s.Contains(TEXT_TO_SEARCH)) {
                // output it
            }
        }
    }
}
