c# - How to check if a file exists in a folder?

Question

I need to check if an xml file exists in the folder.

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
    log.Info("no files present")
}

Is this the best way to check a file exists in the folder.

I need to check just an xml file is present

Answer 1

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.
