System.IO.DirectoryInfo downloadedMessageInfo =新的DirectoryInfo（GetMessageDownloadFolderPath（））;

的foreach（在downloadedMessageInfo.GetFiles FileInfo的文件（））
{
    file.Delete（）;
}
的foreach（DirectoryInfo的目录中downloadedMessageInfo.GetDirectories（））
{
    dir.Delete（真正的）;
}
 

Using C#, how can I delete all files and folders from a directory, but still keep the root directory?

System.IO.DirectoryInfo downloadedMessageInfo = new DirectoryInfo(GetMessageDownloadFolderPath());

foreach (FileInfo file in downloadedMessageInfo.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in downloadedMessageInfo.GetDirectories())
{
    dir.Delete(true); 
}
