How to run the first file existing with the selected format?-CodePudding

I would like to read an existing html file from a folder and run it. I know, I could run given a specific file, the problem is that my program will delete the previous HTML file and generate anew with a different file name.

All I know is that the process to start running the program is:

Process.Start("firefox.exe", $@"C:\Users\domin\..\*.html");

This is just my imagination of how it would be done, but that is not the way. How can I do that?

CodePudding user response：

You could use FileSystemWatcher in folder path and add the required filters and events to it. And write your logic in the event.

CodePudding user response：

var ext = new List<string> { "html" };
var myFiles = Directory
   .EnumerateFiles(pathResult, "*.*", SearchOption.AllDirectories)
   .Where(s => ext.Contains(Path.GetExtension(s).TrimStart('.').ToLowerInvariant()));

var filehtml = myFiles.First();

var p = new Process();
p.StartInfo = new ProcessStartInfo($@"{filehtml}")
{
   UseShellExecute = true
};
p.Start();

This was solved my problem
