CSharp删除文件或文件夹

前面啥也没有

删除文件

public void DeleteFiles(string path)
{
    try
    {
        string[] files = Directory.GetFiles(path);
        List<string> picFiles = new List<string>();
        foreach (string f in files)
        {
            string fileName = Path.GetFileName(f);
            if (fileName.ToUpper().Contains("LW"))
                picFiles.Add(f);
        }
        picFiles.ForEach((f) =>
        {
            FileInfo fi = new FileInfo(f);
            DateTime dtWrite = fi.LastWriteTime;
            if ((DateTime.Now - dtWrite).Days > deleteDays)
                fi.Delete();
        });
    }
    catch (System.Exception ex)
    {
        
    }
}

删除文件夹

string[] directories = Directory.GetDirectories(path);
directories.ToList().ForEach((dir) =>
{ 
    if ((DateTime.Now - Directory.GetLastWriteTime(dir)).Days > deleteDays)
        Directory.Delete(dir, true);
});
