如何将文件从一个目录复制到另一目录？

Question

string[] s = Directory.GetFiles(t, "*.txt",SearchOption.AllDirectories);
for (int i = 0; i < s.Length; i++)
{
    File.Copy(s[i],
}

File.Copy will copy the files to another file name. I want to keep the same files names just copy them from one directory to another directory.

Answer 1

用这个：

 File.Copy(s[i], "c:\\anotherFolder\\" + Path.GetFileName(s[i]));

Answer 2

You can do it nicely like this:

Directory.GetFiles("c:\\temp", "*.txt", SearchOption.AllDirectories) // get the files
    .Select(c => new FileInfo(c)) // project each filename into a fileinfo
    .ToList() // convert to list
    .ForEach(c => c.CopyTo("d:\\temp\\" + c.Name)); // foreach fileinfo, copy to the desired path + the actual file name

You could view this post, which should help;

Or this MSDN link:

Code snippet:

var sourceDir = @"c:\sourcedir";
var destDir = @"c:\targetdir";
var pattern = "*.txt";

foreach (var file in new DirectoryInfo(sourceDir).GetFiles(pattern))
{
   file.CopyTo(Path.Combine(destDir, file.Name));
}

Hope this helps?
