How to Rename C# files being moved from source to destination folders using prefix of directory name on each file?

In C# while moving files from source to destination folders, how to rename the destination file with prefix of directory name to each file?

static void Main(string[] args)
{
string sourceFolder = #"C:\Source";
string destinationFolder = #"C:\Destination\";
string dirName = Path.Combine(destinationFolder, DateTime.Now.ToString("dd-MM-yyyy"));
Directory.CreateDirectory(dirName);
DirectoryInfo di = new DirectoryInfo(sourceFolder);
string searchXlsPattern = "*.xls*";
try
{
//Getting list of files from Nested sub folders
ICollection<FileInfo> files = di.GetFiles(searchXlsPattern, SearchOption.AllDirectories).Where(file => !file.DirectoryName.Contains("Archive"))
.Select(x => x)
.ToList();
if (files != null && files.Count() > 0)
{
foreach (FileInfo currentfile in files)
{
if (new FileInfo(dirName + "\\" + currentfile.Name).Exists == false)
{
//Renaming old file name to new file Name
string fileDirectoryName = "";
fileDirectoryName = Path.GetDirectoryName(currentfile.FullName);
string replaceSlash = Convert.ToString(fileDirectoryName.Replace("\\", "_"));
string replaceSplChar= replaceSlash.Replace(":", "_");
string fileextension = Path.GetExtension(currentfile.Name);
string fname = currentfile.Name.Replace(fileextension, "");
string newFileName = replaceSplChar.ToString()+ "_" + fname + fileextension;
//Copy the file to destination folder
//tempfile.CopyTo(Path.Combine(destinationFolder, newFileName), true);
//Move the file to destination folder
currentfile.MoveTo(dirName + "\\" + newFileName);
////File.Move(currentfile.DirectoryName + "\\" + currentfile.Name, dirName + "\\" + newFileName);
//File.Move(currentfile.DirectoryName + "\\" + currentfile.Name, dirName + "\\" + newFileName);
}
}
}
else
Console.Write("There is no files in Source");
}
catch (IOException Exception)
{
Console.Write(Exception);
}
}

Copy picture to folder and rename the copy with numbers from 1, sequentially

Here is all I want to do: Every time the button is clicked, an openfile dialog is opened, the user clicks on a picture, then this picture is copied to a specific folder and renamed to a number. Every picture's name in this folder should be a number, but they must all be different. My code so far:
if (openfile.ShowDialog() == DialogResult.OK)
{
try
{
File = Image.FromFile(openfile.FileName);
pictureBox3.Image = File;
int i = 0;
if (System.IO.File.Exists(picturedir + "\\" + i.ToString() + ".png") == true)
{
i++;
MessageBox.Show(picturedir + "\\" + i.ToString() + ".png" + ".....Already Exists.");
}
else if (System.IO.File.Exists(picturedir + "\\" + i.ToString() + ".png") == false)
{
System.IO.File.Copy(openfile.FileName, picturedir + "\\" + i.ToString() + ".png", true);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Of course here, the first picture is copied and renamed to "0.png" but the next pictures are not copied at all, because the "if" gives true. Any ideas ? Thanks.

You could do this:
...
int i = 0;
while (System.IO.File.Exists(picturedir + "\\" + i.ToString() + ".png") == true)
{
i++;
// I wouldn't show that message each time, gonna get pretty old for lots of pics!
}
System.IO.File.Copy(openfile.FileName, picturedir + "\\" + i.ToString() + ".png", true);
...

If you want the next number, you can enumerate the existing files, find the maximum number now in use and add 1. Something like:
var files = Directory.EnumerateFiles(myCurrentDirectory, "*.png");
var fileNumStrings = from file in files select Path.GetFileNameWithoutExtension(file);
var max = 0;
foreach (var fileNumString in fileNumStrings)
{
if (int.TryParse(fileNumString, out var filenum))
{
if (filenum > max)
{
max = filenum;
}
}
}
var nextNum = max + 1;

Not able to save file from dynamically generated fileupload controls

I have a project wherein fileupload controls are generating dynamically. Using Json, I'm trying to save file in a directory asynchronously. I want to save files with filename using handler template in asp.net 4.0.
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: Sitepath + "Handler/FileUploader.ashx?filename="+strfiles,
secureuri: false,
fileElementClass: "multi",
dataType: "json",
async: false
});
I've added HTTPPostedFile's logic outside FileUploader class as it was throwing error in that.
public class FileUploader : IHttpHandler, IRequiresSessionState
{
public void ProcessRequest(HttpContext context)
{
string rt = "";
HttpContext.Current.Response.ContentType = "text/HTML";
string urlresponse = HttpContext.Current.Request.Url.ToString();
string tempfiles = "";
string filenames = "";
int convert = urlresponse.IndexOf(",");
urlresponse = urlresponse.Substring(convert + 1);
string[] filesArray = urlresponse.Split(',');
for (int i = 0; i < filesArray.Length; i++)
{
tempfiles = filesArray[i].ToString();
int lstIndex=tempfiles.LastIndexOf("\\");
filenames = filenames + "," + tempfiles.Substring(lstIndex + 1);
}
filenames = filenames.Substring(filenames.IndexOf(',') + 1);
HttpFileCollection uploads = HttpContext.Current.Request.Files;
string b = HttpContext.Current.Request.Url.ToString();
Hashtable hashtable = new Hashtable();
// Declare variable
string OrderFileName = String.Empty;
string OrderIDs =String.Empty;
string TempFolder = String.Empty;
if (HttpContext.Current.Session["OrderID"] != null)
{
OrderIDs = HttpContext.Current.Session["OrderID"].ToString();
string mapPath = HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["DocPath"].ToString());
string mapPathUserId = mapPath + "\\" + HttpContext.Current.Session["UserID"];
///
var g = filenames.Split(',');
for (int t = 0; t < g.Length;t++ )
{
var h = g[t];
rt = filesArray[t].ToString();
if (Directory.Exists(mapPathUserId) == false)
{
Directory.CreateDirectory(mapPathUserId);
}
string mapPathCount = mapPathUserId + "/" + OrderIDs;
if (Directory.Exists(mapPathCount) == false)
{
//--------------Begin(Create Directory)----------------------------------------------------------------------------------//
Directory.CreateDirectory(mapPathCount);
//--------------End(Create Directory)----------------------------------------------------------------------------------//
}
TempFolder = mapPathUserId + "/" + "Temp";
if (Directory.Exists(TempFolder) == false)
{
//--------------Begin(Create Directory for temp folder)----------------------------------------------------------------------------------//
Directory.CreateDirectory(TempFolder);
//--------------End(Create Directoryfor temp folder)----------------------------------------------------------------------------------//
}
OrderFileName = h;
hashtable.Add(t.ToString(), OrderFileName);
var see = HttpContext.Current.Server.MapPath(TempFolder + "/" + OrderFileName);
}
Now, path is being created successfully, but file is not getting saved in specified directory. My code to save the file:
for (int i = 0; i < uploads.Count; i++)
{
HttpPostedFile upload = uploads[i];
if (Directory.Exists(mapPathUserId) == false)
{
Directory.CreateDirectory(mapPathUserId);
}
string mapPathCount = mapPathUserId + "/" + OrderIDs;
if (Directory.Exists(mapPathCount) == false)
{
//--------------Begin(Create Directory)----------------------------------------------------------------------------------//
Directory.CreateDirectory(mapPathCount);
//--------------End(Create Directory)----------------------------------------------------------------------------------//
}
/// Create Path for Temp Folder
TempFolder = mapPathUserId + "/" + "Temp";
if (Directory.Exists(TempFolder) == false)
{
//--------------Begin(Create Directory for temp folder)----------------------------------------------------------------------------------//
Directory.CreateDirectory(TempFolder);
//--------------End(Create Directoryfor temp folder)----------------------------------------------------------------------------------//
}
if (upload.ContentLength > 0)
{
if (upload.FileName.Contains(" "))
{
OrderFileName = upload.FileName.Replace(" ", "_");
}
else
{
OrderFileName = upload.FileName;
}
hashtable.Add(i.ToString(), OrderFileName);
upload.SaveAs(TempFolder + "/" + OrderFileName);
}
}
Please help.

You have to make sure you pass a right path, in the server. I would try mapping the path with the MapPath() function:
upload.SaveAs(Server.MapPath(TempFolder + "/" + OrderFileName));

Moving folder from one location to another in a web service

I have a web service that locates files in a folder (C:\Incoming) and emails them to a specified email address. I want to be able to move that folder, once it has been mailed to another folder (C:\Processed).
I tried using this code below, but it does not work.
string SourceFile = "C:\\Incoming\\" + "" + Year + "" + Month + "" + Day + "";
string destinationFile = "C:\\Processed" + "" + Year + "" + Month + "" + Day + "";
System.IO.File.Move(SourceFile , destinationFile);
I get an error saying that the sourcefile could not be found. I have verified that it does exist and I have access to it.

You are moving folders not file you will need to iterate over files to copy one by one.
string Source = "C:\\Incoming\\" + "" + Year + "" + Month + "" + Day + "";
string destination = "C:\\Processed" + "" + Year + "" + Month + "" + Day + "";
DirectoryInfo di = new DirectoryInfo(Source);
FileInfo[] fileList = di.GetFiles(".*.");
int count = 0;
foreach (FileInfo fi in fileList)
{
System.IO.File.Move(Source+"\\"+fi.Name , destinationFile+"\\"+fi.Name);
}

Use String.Format for one, second use System.IO.File.Exists() to make sure the file is there.
string SourceFile = String.Format("C:\\Incoming\\{0}{1}{2}",Year,Month,Day);
string destinationFile = String.Format("C:\\Processed\\{0}{1}{2}",Year,Month,Day);
if (System.IO.File.Exists(SourceFile) {
System.IO.File.Move(SourceFile , destinationFile);
}

Change filename on file upload in .net (asp)

How to change file name on upload ?
I have such code :
<%# WebHandler Language="C#" Class="Upload" %>
using System;
using System.Web;
using System.IO;
public class Upload : IHttpHandler {
public void ProcessRequest(HttpContext context) {
HttpPostedFile oFile = context.Request.Files["Filedata"];
string newFileName1 = HttpContext.Current.Server.MapPath(#context.Request["orderID"]);
string newFileName2 = HttpContext.Current.Server.MapPath(#context.Request["productCombinationString"]);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + oFile.ContentType;
} else {
newName = newFileName1 + oFile.ContentType;
}
string sDirectory = HttpContext.Current.Server.MapPath(#context.Request["folder"]);
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
context.Response.Write("1");
}
public bool IsReusable {
get { return false; }
}
}
And if i change oFile.Filename to newName it does not work ... what is the problem ? :)
Thank you

You can pass your Custom File Name along with Directory to SaveAs Method
oFile.SaveAs(sDirectory + "/" + "abc");

try:
// Get the extension of the uploaded file.
string fileName = Server.HtmlEncode(FileUpload1.FileName);
string extension = System.IO.Path.GetExtension(fileName);
string newName;
if(newFileName2 != "" && newFileName2 != null && newFileName2 != "<!--#Ecom:productCombinationString-->") {
newName = newFileName1 + newFileName2 + extension ;
} else {
newName = newFileName1 + extension ;
}
oFile.SaveAs(sDirectory + "/" + newName );

I haven't tried this code but I do want to point out two things of from the original code:
The first is this order of operations:
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
if (!Directory.Exists(sDirectory)) Directory.CreateDirectory(sDirectory);
I believe it should be this instead. In the above sequence, there is a potential edge case of saving into a non-existing folder. This ensures that the folder is created:
if (!Directory.Exists(sDirectory))
{
Directory.CreateDirectory(sDirectory);
}
oFile.SaveAs(sDirectory + "/" + oFile.FileName);
The other thing is that you might be running into issues with / as the path separator. I think it should be much safer to do something like:
var saveLocation = Path.Combine(sDirectory, oFile.FileName);
oFile.SaveAs(saveLocation);
I hope this helps!

Here is an example i used when saving an image look at the save as section
////saving file in the physical folder;
FileUpload FileUpload1 = file_Image;
string virtualFolder = "~/Resourceimages/";
string physicalFolder = HostingEnvironment.MapPath(virtualFolder);
string PhotoName = ((string)Session["UserName"] + (string)Session["UserSurname"]);
FileUpload1.SaveAs(physicalFolder + PhotoName + FileUpload1.FileName);
string location = virtualFolder + PhotoName + FileUpload1.FileName;
webservice.UpdateResourceImage((int)Session["UserID"], location);
lbl_Result.Text = "Your file " + FileUpload1.FileName + " has been uploaded.";
Image1.Visible = true;
Image1.ImageUrl = location;

string uploadFolder = Request.PhysicalApplicationPath + "UploadFile\\";
if (FileUpload1.HasFile)
{
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(uploadFolder + "Test"+ extension);
Label1.Text = "File uploaded successfully as: " + "Test"+ extension;
}
else
{
Label1.Text = "First select a file.";
}

private string UpdateFilename(string filename)
{
try
{
filename = Server.HtmlEncode(FUJD.FileName);
string extension = System.IO.Path.GetExtension(filename);
filename = filename.Replace(extension, "");
return filename + '-' + DateTime.Now.ToString("yyyyMMddHHmmss") + extension;
