}

Before calling the CopyDirectory method, you can determine whether the original path and the target path exist.


if (directory.exists (Srcpath) &&directory.exists (DestPath)) { copydirectory (Srcpath,destpath);
}

C # Delete all files under a folder
public static void Delectdir (String srcpath)
{ try { DirectoryInfo dir = new DirectoryInfo (srcpath); filesysteminfo[] FileInfo = dir. Getfilesysteminfos (); Returns all files and subdirectories in the directory foreach (FileSystemInfo i in FileInfo) { if (I am DirectoryInfo) //Determine if the folder { DirectoryInfo subdir = new DirectoryInfo (i.fullname); SubDir. Delete (true); Delete subdirectories and files } else { file.delete (i.fullname); Delete specified file } } } catch (Exception e) { throw; }
}

You can determine whether a folder exists before calling the Delectdir method

if (directory.exists (Srcpath)) {    delectdir (srcpath);}
