C#复制文件代码
private void Copy() { DirectoryInfo dir = new DirectoryInfo("c:\\CSS"); CopyDirectorysAndFiles("c:\\test", dir); } private void CopyDirectorysAndFiles(string dest, DirectoryInfo srcdir) { if (dest.LastIndexOf('\\') != (dest.Length - 1)) { dest += "\\"; } string destPath = dest +srcdir.Name + "\\"; if (!Directory.Exists(destPath)) { Directory.CreateDirectory(destPath); } FileInfo[] files = srcdir.GetFiles(); foreach (FileInfo file in files) { file.CopyTo(destPath + file.Name, true); } DirectoryInfo[] dirs = srcdir.GetDirectories(); foreach (DirectoryInfo dirInfo in dirs) { CopyDirectorysAndFiles(destPath, dirInfo); } }
-----------------------------------
C#拷贝文件原来的文件路径名FileOldPath;
新的文件路径名:FileNewPath,
那就可以用
File.Move(FileOldPath,FileNewPath) 或者File.Copy(FileOldPath,FileNewPath)
注意的是这里的路径是文件夹路径+文件名,可以用Path.Combine()来实现
----------------------------------
一般是先复制,再删除~
System.IO.File.Move(File, newfile); System.IO.File.Copy(File, newfile); System.IO.File.Detele(File);
