We have a .net program and we create various log files and want to delete them after a certain amount of time. What is the best way to do this?

You can loop through the directory and check the time against a target value. For example, if you wanted to delete those older than 30 days, you could use:
public static void PurgeDirectory(string path)
{
    System.IO.DirectoryInfo info = new System.IO.DirectoryInfo(path);
    DateTime targetDate = DateTime.Now.AddDays(-30);

    foreach (System.IO.FileInfo fi in info.GetFiles())
    {
        if (fi.LastAccessTime > targetDate)
        {
            fi.Delete();
        }
    }
}

If you use the above, you should be a bit more cautious by checking that the path exists before trying to get its files:
public static void PurgeDirectory(string path)
{
    System.IO.DirectoryInfo info = new System.IO.DirectoryInfo(path);

    if (info.Exists)
    {
        DateTime targetDate = DateTime.Now.AddDays(-30);

        foreach (System.IO.FileInfo fi in info.GetFiles())
        {
            if (fi.LastAccessTime > targetDate)
            {
                fi.Delete();
            }
        }
    }
}
