将文件从一个文件夹复制到另一个 [英] copying files from one folder to another

问题描述

我在文件夹中有一组文本文件。我想将这个文件夹复制到另一个名称和数据时间的文件夹中。

Hi,
I have set of text files in folder. I want to copy this folders into another folder with name and datatime.

string directory = @"C:\Documents and Settings\vinodhini\Desktop\Merge Data\SampleData";

string comdir = @"C:\Documents and Settings\vinodhini\Desktop\Merge Data\CompletedData";
string[] fiels = System.IO.Directory.GetFiles(directory);
foreach (string s in fiels)
            {
               
                string st = DateTime.Now.ToShortDateString();
               string  fileName = System.IO.Path.GetFileName(s)+st;
               string  destFile = System.IO.Path.Combine(comdir, fileName);
               System.IO.File.Copy(s, destFile, true);
            
            }

但我得到不支持给定路径的格式这个错误。



有人帮我解决这个问题吗？

But i got "The given path's format is not supported" this error.

Anyone help me to solve this?

推荐答案

尝试使用这个...

try using this...

string st = Date.Now.Year + Date.Now.Month + Date.Now.Day //outputs the date without "/"

我在VB.Net中尝试过。它运作良好。

I tried it in VB.Net. It works well.

嗯......已经做了很小的改动：

Hmmm... Small changes have been done:

string directory = @"C:\Documents and Settings\vinodhini\Desktop\Merge Data\SampleData";
string comdir = @"C:\Documents and Settings\vinodhini\Desktop\Merge Data\CompletedData\" + DateTime.Now.ToString("yyyyMMdd") + "\";

string[] fiels = System.IO.Directory.GetFiles(directory);
foreach (string s in fiels)
            {
               string  fileName = System.IO.Path.GetFileName(s);
               string  destFile = System.IO.Path.Combine(comdir, fileName);
               System.IO.File.Copy(s, destFile, true);
            }

谢谢你我解决了自己
