get most recently created file in a directory

[LrngToFly]

Hi-

I'm not a C# programmer and I need to add some code to a project that determines the most recently created file in a directory.

I'm not familiar with the .Net framework. I'm happy to work on syntax problems and any loops- but can someone sketch out what kinds of calls I should use?

Thanks! Andy

I think this should work :

using System.IO;

public class FileHelper
{
    static public string GetMostRecentFile(string sFolderPath)
    {
        DateTime dateTime;
        bool fFirst = true;
        string sMostRecentFile = "";
    
        foreach (string sFile in Directory.GetFiles(sFolderPath))
        {
            if (fFirst)
            {
                fFirst = false;
                dateTime = File.GetCreationTime(Path.Combine(sFolderPath, sFile));
                sMostRecentFile = sFile;
            }
            else
            {
                DateTime dateTimeFile = File.GetCreationTime(Path.Combine(sFolderPath, sFile));

                if (dateTimeFile > dateTime)
                {
                    dateTime = dateTimeFile;
                    sMostRecentFile = sFile;
                }
            }
        }

        return Path.Combine(sFolderPath, sMostRecentFile);
    }
}

If not, it should show you how to do it anyway.
