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

{    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.

}

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

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