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);
