I need to send a file from one folder to the next by date,

Question

I am a newb :) Anyways thanks in advance. I am trying to figure this out I am sorting through text files in folder 1 in which it seems to work fine. But when I add this line of code in

File.Move(fileNames, filetransfered); It errors out giving me "The best overloaded method match for 'System.IO.File.Move(string, string)' has some invalid arguments "

From what I read the file.move( , ); supposed to move the file from folder 1 into the second folder

Here is the code. Thank you for any help.

    class Program
    {
        static void Main(string[] args)
        {

            string[] fileNames = Directory.GetFiles(@"c:\Users\Rob\Desktop\1", "*.txt");
            string filetransfered = @"c:\Users\Rob\Desktop\2";

            // Now read the creation time for each file
            DateTime[] creationTimes = new DateTime[fileNames.Length];
            for (int i = 0; i < fileNames.Length; i++)
                creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;

            // sort it
            Array.Sort(creationTimes, fileNames);

            File.Move(fileNames, filetransfered);

HI Blehugh,

         The syntax of  File.move is 

file.move(path, destinationPath);

your string "filetransfered" is correct but in "fileNames" u r using array instead of a single string path.
ur code should like this:

class Program
    {
        static void Main(string[] args)
        {

            string fileName = @"c:\Users\Rob\Desktop\1";
            string filetransfered = @"c:\Users\Rob\Desktop\2";

            // Now read the creation time for each file
            DateTime[] creationTimes = new DateTime[fileNames.Length];
            for (int i = 0; i < fileNames.Length; i++)
                creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;

            // sort it
            Array.Sort(creationTimes, fileNames);

            File.Move(fileNames, filetransfered);

remember  File.move required two arguments one for source file path and second for destination file path  "file.move(sourceFilePath , destinationFilePath)"

if u can't understand anything.....plz reply.... i will try to help u
regards,

using System;
using System.IO;

namespace MoveFiles
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] fileNames = Directory.GetFiles(@"C:\Users\Rob\Desktop\1", "*.txt");
            string filetransfered = @"C:\Users\Rob\Desktop\2";

            // Now read the creation time for each file
            DateTime[] creationTimes = new DateTime[fileNames.Length];
            for (int i = 0; i < fileNames.Length; i++)
                creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;

            // sort it
            Array.Sort(creationTimes, fileNames);

            if (false == Directory.Exists(filetransfered))
            {
                Directory.CreateDirectory(filetransfered);
            }
            //File.Move(fileNames, filetransfered);
            foreach (string filename in fileNames)
            {
                File.Move(filename, String.Format(@"{0}\{1}", filetransfered, Path.GetFileName(filename)));
            }
        }
    }
}

Answer 3

Ya I figured it was the single string part but I am still erroring on lines   new FileInfo(fileName[i])  and  Array.Sort(creationTimes, fileName);

  The best overloaded method match for 'System.Array.Sort<System.DateTime>(System.DateTime[], System.Comparison<System.DateTime>)' has some invalid arguments   

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

             string fileName = @"c:\Users\RStamper\Desktop\A";
            string filetransfered = @"c:\Users\RStamper\Desktop\B";

            // Now read the creation time for each file
            DateTime[] creationTimes = new DateTime[fileName.Length];
            for (int i = 0; i < fileName.Length; i++)
                creationTimes[i] = new FileInfo(fileName[i]).CreationTime;

            // sort it
            Array.Sort(creationTimes, fileName);

            File.Move(fileName, filetransfered);
       }
   }
}

Dear Sam this works but its transferring all the files not the last one last added. I think it has something to do with the loop around moves.

Answer 5

using System;
using System.IO;

namespace MoveFiles
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] fileNames = Directory.GetFiles(@"C:\Users\Rob\Desktop\1", "*.txt");
            string filetransfered = @"C:\Users\Rob\Desktop\2";

            // Now read the creation time for each file
            DateTime[] creationTimes = new DateTime[fileNames.Length];
            for (int i = 0; i < fileNames.Length; i++)
                creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;

            // sort it
            Array.Sort(creationTimes, fileNames);

            if (false == Directory.Exists(filetransfered))
            {
                Directory.CreateDirectory(filetransfered);
            }
            //File.Move(fileNames, filetransfered);
            foreach (string filename in fileNames)
            {
                File.Move(filename, String.Format(@"{0}\{1}", filetransfered, Path.GetFileName(filename)));
            }
        }
    }
}

You almost had it Sam, thanks a ton I got it figured out now took about 4 hours but oh well :) Thanks again.... here it is if anyone needs it. It will transfer a file by date from one folder to the next. Very cool.. Thanks again

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
       // public static void transferFiles()
        public static void Main()
        {
            string[] fileNames = Directory.GetFiles(@"C:\Users\RStamper\Desktop\A", "*.xml");
            string filetransfered = @"C:\Users\RStamper\Desktop\B";

            DateTime[] creationTimes = new DateTime[fileNames.Length];
            for (int i = 0; i < fileNames.Length; i++)
                creationTimes[i] = new FileInfo(fileNames[i]).CreationTime;

               Array.Sort(creationTimes, fileNames);

            if (false == Directory.Exists(filetransfered))
            {
              Directory.CreateDirectory(filetransfered);
            }

              String filename = fileNames[fileNames.Length - 1]; //gets the last file
           if (!File.Exists(filetransfered))
            {   
                File.Move(filename, String.Format(@"{0}\{1}", filetransfered, Path.GetFileName(filename)));
                File.Delete(filename);              
           }

        }
    }
}
