ASP.Net FileUpload: Rename file name before saving if already exists

I need change file name when users upload from file upload control.
If file name be duplicate it add count at file name but here it doesn't work.
I mean when I upload file i.e. 00076007-2013.pdf it saves in the host with this name 00076007-2013(0).pdf
But when again I want upload 00076007-2013.pdf in host it overwrite last (00076007-2013(0).pdf).
But I want if there was 00076007-2013.pdf file it saves with this name 00076007-2013(1).pdf in host.
How I can solve this problem.
My code below.
int count = 0;
string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
string FileExstention = Path.GetExtension(FileUpload1.FileName);
string[] files = Directory.GetFiles(Server.MapPath("/public/2Version/sk_PDF/"));
if (FileUpload1.HasFile)
{
if (FileExstention == ".pdf")
{
try
{
if (File.Exists(Server.MapPath("/public/2Version/sk_PDF/") + fileName.ToString()))
{
foreach (string s in files)
{
string filename = string.Empty;
filename = Path.GetFileName(s).Substring(0, Path.GetFileName(s).LastIndexOf("."));
if (filename.Contains("("))
{
filename = filename.Substring(0, filename.LastIndexOf("("));
}
if (filename == fileName.ToString().Trim())
{
count++;
}
FileUpload1.PostedFile.SaveAs(Server.MapPath("/public/2Version/sk_PDF/") + filename.ToString() + "(" + count.ToString() + ")" + FileExstention);
}
}
else
{
FileUpload1.PostedFile.SaveAs(Server.MapPath("/public/2Version/sk_PDF/") + fileName.ToString());
}
}
catch (Exception ex)
{
throw ex;
}
}
}
Edit #01
This is the output.
I have upload the 00076007-2013.pdf file for three times.
The first time OK, 00076007-2013.pdf.
The second time OK, 00076007-2013(0).pdf.
The last time he was saved 00076007-2013(0).pdf and not 00076007-2013(1).pdf

Please change this part :
if (filename.Contains("("))
{
filename = filename.Substring(0, filename.LastIndexOf("("));
}
With :
if (filename.Contains("("))
{
filename = filename.Substring(0, filename.LastIndexOf("("));
count++;
}
I hope I was helpful.

how to store and retrieve multiple values inside single session variable

i am using dropzone to upload multiple files to the server. files will be uploaded to server while file names will be stored in table.
i am trying to add file names in session.
the problem here is that it doesn't add multiple file names inside single session
here is my code :
string imageSessList = context.Session["imageNames"].ToString(); //if i put this line at the begining, then the debugger doesn't even moves to foreach block
foreach (string s in context.Request.Files)
{
HttpPostedFile file = context.Request.Files[s];
string fileName = file.FileName;
string fileExtension = file.ContentType;
string strUploadFileExtension = fileName.Substring(fileName.LastIndexOf(".") + 1);
string strAllowedFileTypes = "***jpg***jpeg***png***gif***bmp***"; //allowed file types
string destFileName = "";
List<string> lstImageNames = new List<string>();
// else upload file
if (!string.IsNullOrEmpty(fileName))
{
if (strAllowedFileTypes.IndexOf("***" + strUploadFileExtension + "***") != -1) //check extension
{
if (context.Request.Files[0].ContentLength < 5 * 1024 * 1024) //check filesize
{
// generate file name
destFileName = Guid.NewGuid().ToString() + "." + strUploadFileExtension;
string destFilePath = HttpContext.Current.Server.MapPath("/resourceContent/") + destFileName;
//Save image names to session
lstImageNames.Add(destFileName);
context.Session["imageNames"] = lstImageNames;
file.SaveAs(destFilePath);
strMessage = "Success " + destFileName;
}
else
{
strMessage = "File Size can't be more than 5 MB.";
}
}
else
{
strMessage = "File type not supported!";
}
}
} // foreach
context.Response.Write(strMessage);
}
here i am able to add only single filename to session, not multiple.
how to store and maintain multiple file names in single session :
context.Session["imageNames"]

you need to get current list from session
List<string> lstImageNames= (List<string>)Session["imageNames"];
if(lstImageNames==null)
lstImageNames = new List<string>(); // create new list in the first time
now add new item to it.
lstImageNames.Add(destFileName);
set back to session
context.Session["imageNames"] = lstImageNames;

Get files from a folder that I have created in Xamarin.Android

I want get all files from an external storage folder(wall_e_imgs)..Here are codes-
public void getImages()
{
var path1 = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath.ToString();
string path = System.IO.Path.Combine(path1, "wall_e_imgs");
//var files= System.IO.Directory.GetFiles(Android.OS.Environment.ExternalStorageDirectory.ToString() + "wall_e_imgs");
//var files = System.IO.Directory.GetFiles(path);
//string path = Android.OS.Environment.ExternalStorageDirectory.ToString() + "/wall_e_imgs";
//File directory=new File(path);
Java.IO.File directory = new Java.IO.File(path);
Java.IO.File[] files = directory.ListFiles();//always count is 0 even though there are lot files there
foreach (var i in files)
{
FileInfo info = new FileInfo(i.Name);
if (info.Name.Contains("Wall_e"))
{
di.Add(new DownloadedImages { Path1 = info.DirectoryName, Name1 = info.FullName });
}
}
}
But it always give 0 files even though there are lot of files.

Try this
var folder = Android.OS.Environment.ExternalStorageDirectory + Java.IO.File.Separator + "yourfoldername";
if (!Directory.Exists(folder))
Directory.CreateDirectory(folder);
var filesList = Directory.GetFiles(folder);
foreach (var file in filesList)
{
var filename = Path.GetFileName(file);
}

Try something like this:
// Use whatever folder path you want here, the special folder is just an example
string folderPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "wall_e_imgs");
if (Directory.Exists(folderPath))
{
var files = Directory.EnumerateFiles(folderPath);
foreach (var file in files)
{
// Do your stuff
}
}
Please note that this uses the Directory class from System.IO, not Java.IO

ffilelist will contain a list of mp3 files in "/storage/emulated/0/Music/"
string phyle;
string ffilelist = "";
public void listfiles()
{
try
{
var path1 = "/storage/emulated/0/Music/";
var mp3Files = Directory.EnumerateFiles(path1, "*.mp3", SearchOption.AllDirectories);
foreach (string currentFile in mp3Files)
{
phyle = currentFile;
ffilelist = ffilelist + "\n" + phyle;
}
//playpath(phyle); // play the last file found
}
catch (Exception e9)
{
Toast.MakeText(ApplicationContext, "ut oh\n"+e9.Message , ToastLength.Long).Show();
}
}

Creating unique files in another directory

Currently i am taking in multiple .txt files from a directory i have specified (sourceDirectory). I am generating new .csv files with the same name as the .txt files - one .csv file for each .txt file.
However i want to generate these new files in another directory which i have specified (directoryPath). If i run my program once it creates these files in the initial directory, however if i run my program again it now generates the files in the destination directory.
The following is my code where i complete the above:
static void Main(string[] args)
{
string sourceDirectory = #"C:directoryWhereTXTFilesAre";
var txtFiles = Directory.EnumerateFiles(sourceDirectory, "*.txt", SearchOption.AllDirectories);
foreach (string currentFile in txtFiles)
{
readFile(currentFile);
}
string directoryPath = #"C:\destinationForCSVFiles";
}
I then create the new .csv files name based on the original .txt file like this:
static FileStream CreateFileWithUniqueName(string folder, string fileName, int maxAttempts = 1024)
{
var fileBase = Path.GetFileNameWithoutExtension(fileName);
var ext = Path.GetExtension(fileName);
// build hash set of filenames for performance
var files = new HashSet<string> (Directory.GetFiles(folder));
for (var index = 0; index < maxAttempts; index++)
{
// first try with the original filename, else try incrementally adding an index
var name = (index == 0)
? fileName
: String.Format("{0} ({1}){2}", fileBase, index, ext);
// check if exists
var fullPath = Path.Combine(folder, name);
string CSVfileName = Path.ChangeExtension(fullPath, ".csv");
if (files.Contains(CSVfileName))
continue;
// try to create the file
try
{
return new FileStream(CSVfileName, FileMode.CreateNew, FileAccess.Write);
}
catch (DirectoryNotFoundException) { throw; }
catch (DriveNotFoundException) { throw; }
catch (IOException)
{
}
}
I don't see why it's creating the .csv files initially in the same directory that the .txt files are in and then second time i run my code it creates them in the directoryPath.
Desired output: sourceDirectory left as it is with only .txt files and directoryPath to hold the .csv files.
The only other place i call CreateFileWithUniqueName is within my readFile method, the code is below:
using (var stream = CreateFileWithUniqueName(#"C:destinationFilePath", currentFile))
{
Console.WriteLine("Created \"" + stream.Name + "\"");
newFileName = stream.Name;
Globals.CleanedFileName = newFileName;
}

It seems that you are passing the full filename of the source file. This confuses the Path.Combine inside the CreateFileWithUniqueFilename because you are falling in this subtle remarks found on the documentation of Path.Combine
paths should be an array of the parts of the path to combine. If the
one of the subsequent paths is an absolute path, then the combine
operation resets starting with that absolute path, discarding all
previous combined paths.
You can fix it easily with
using (var stream = CreateFileWithUniqueName(#"C:\destinationFilePath",
Path.GetFileName(currentFile)))
{
Console.WriteLine("Created \"" + stream.Name + "\"");
newFileName = stream.Name;
Globals.CleanedFileName = newFileName;
}
Or better extract the filename without path inside the CreateFileWithUniqueName
static FileStream CreateFileWithUniqueName(string folder, string fileName, int maxAttempts = 1024)
{
var fileBase = Path.GetFileName(fileName);
fileBase = Path.GetFileNameWithoutExtension(fileBase);
var ext = Path.GetExtension(fileBase);
also, you should build your CSVfileName using the cleaned filename
var name = (index == 0)
? String.Format("{0}{1}", fileBase, ext);
: String.Format("{0} ({1}){2}", fileBase, index, ext);
var fullPath = Path.Combine(folder, name);
string CSVfileName = Path.ChangeExtension(fullPath, ".csv");
if (files.Contains(CSVfileName))
continue;

c# service renaming files!

I have a windows service , that takes files with metadata(FIDEF) and corresponding video file and , translates the XML(FIDEF) using XSLT .
I get the file directory listing for FIDEF's and if a video file of the same name exists it translates it. That works ok , but it is on a timer to search every minute. I am trying to handle situations where the same file name enters the input directory but is already in the output directory. I just have it changing the output name to (copy) thus if another file enters i should get (copy)(copy).mov but the service won't start with filenames of the same directory already in the output , it works once and then does not seem to pick up any new files.
Any Help would be great as I have tried a few things with no good results. I believe its the renaming methods, but I've put most of the code up in case its a clean up issue or something else.
(forgive some of the names just trying different things).

There is a lot wrong with your code. getFileList has the unneeded inner for loop for starters. Get rid of it. Your foreach loop has s, which can replace filepaths[i] from your for loop. Also, don't do outputPath + result to make file paths. Use Path.Combine(outputPath, result) instead, since Path.Combine handles directory characters for you. Also, you need to come up with a better name for getFileList, since that is not what the method does at all. Do not make your method names liars.
I would simply get rid of MoveVideoFiles. The compiler just might too.
GetUniqueName only works if your file name is of the form name.mov.fidef, which I'm assuming it is. You really need better variable names though, otherwise it will be a maintenance nightware later on. I would get rid of the == true in the while loop condition, but that is optional. The assignment inside the while is why your files get overwritten. You always generate the same name (something(Copy).mov.fidef), and as far as I can see, if the file exists, I think you blow the stack looping forever. You need to fix that loop to generate a new name (and don't forget Path.Combine). Maybe something like this (note this is untested):
int copyCount = 0;
while (File.Exists(ValidName))
{
const string CopyName = "(Copy)";
string copyString = copyCount == 0 ? CopyName : (CopyName + "(" + copyCount + ")");
string tempName = Justname + copyString + Extension2 + Extension;
ValidName = Path.Combine(outputPath, tempName);
copyCount++;
}
This generates something(Copy).mov.fidef for the first copy, something(Copy)(2).mov.fidef for the second, and so on. Maybe not what you want, but you can make adjustments.
At this point you have a lot to do. getMovFile looks as though it could use work in the same manner as GetUniqueName. You'll figure it out. Good luck.
