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

C#

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);
            
            }

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

Anyone help me to solve this?

It is because, the Date is in mm/dd/yy.
As far as I know, "/" is not allowed when naming a file.

Hmmm... Small changes have been done:

C#

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);
            }

Solution 1

try using this...

C#

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

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