Increment file name by 1 if the file exists in c#

I am trying to increment the filename (e.g., "file1.csv", "file2.csv", etc.), each time a new file is generated. I followed this thread Increment the file name if the file already exists in c# but the solution is not useful for my case. What I want to do is check if the file exists in the first place and if it does write in it. If it doesn't create one and write. The problem is that if the file exists but it's from another user, I want the system to increment the file number and not write to the same file just because it exists. What I have so far:
public void saveFile()
{
int count = 0;
string title = "TimeStamp,Name,Trial,Time_spent-dist,Time_spent_tar\n";
string output = System.DateTime.Now.ToString("mm_ss_ffff") + "," +
currentScene.name.ToString() + "," +
trialNum.ToString() + "," +
timerDistractor.ToString() + "," +
timerTarget.ToString();
string fname = "User_" + count + ".csv";
string path = Path.Combine(Application.persistentDataPath, fname);
if (File.Exists(path))
{
File.AppendAllText(path, "\n" + output);
}
else
{
StreamWriter writer = new StreamWriter(path);
writer.WriteLine(title + "\n" + output);
writer.Close();
}
}
Any pointers?

Moving files using SSIS and Script Component

I need to write a code in script component in SSIS that will move files to corresponding folders. Files that I'm getting are usually named, for example "Dem323_04265.45.23.4", "Dem65_459.452.56", "Ec2345_456.156.7894" and I need to move them to a corresponding folders. The name of my folders are "Oklahoma City (323)", "New York(65)".. I need to move those files to matching folders, so for example "Dem323_04265.45.23.4" would go to folder "Oklahoma City (323)". I need to modify my code so the number that is located between first two or three letter and underline matches number located in parenthesis. I've been working on this for several days already and I'm new with ssis and c#, so any help would be appreciated. This is the code I have so far:
public void Main()
{
string filename;
// string datepart;
bool FolderExistFlg;
filename = Dts.Variables["User::FileName"].Value.ToString();
// datepart = (filename.Substring(filename.Length - 12)).Substring(0, 8);
var folderNumber = Regex.Match(
filename,
//Dts.Variables["OutputMainFolder"].Value.ToString(),
#"\(([^)]*)\)").Groups[1].Value;
FolderExistFlg = Directory.Exists(Dts.Variables["OutputMainFolder"].Value.ToString() + "\\" + folderNumber);
if (!FolderExistFlg)
{
Directory.CreateDirectory(Dts.Variables["OutputMainFolder"].Value.ToString() + "\\" + folderNumber);
}
File.Move(Dts.Variables["SourceFolder"].Value.ToString() + "\\" + filename + "\\" + folderNumber,
Dts.Variables["OutputMainFolder"].Value.ToString() + "\\" + filename);
Dts.TaskResult = (int)ScriptResults.Success;
}
#region ScriptResults declaration
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
#endregion
}
}

Here you go, the below snippet would move the files as per the match criteria. You need to take care of the source input as per your configuration.
string filePath = #"C:\Packages\StackOverflow";
//string fileName = string.Empty;
//get list of files
string[] filePaths = Directory.GetFiles(filePath);
//get list of folders
string[] dirPaths = Directory.GetDirectories(filePath);
//loop through the files and move them
foreach(string fileNames in filePaths)
{
string[] pathArr = fileNames.Split('\\');
string fileName = pathArr.Last().ToString();
int index = fileName.IndexOf('_');
string fileNamePart = fileName.Substring(0, index);
//get the first numeric part of the filename to perform the match
var fileNameNumPart = Regex.Replace(fileNamePart, "[^0-9]", "");
//find related directory
var dirMatch = dirPaths.FirstOrDefault(stringToCheck => stringToCheck.Contains(fileNameNumPart.ToString()));
if (dirMatch != null)
{
// move would fail if file already exists in destination
if (!File.Exists(dirMatch + '\\' + fileName))
{
File.Move(fileNames, dirMatch + '\\' + fileName);
}
}
}

This exception occurs very randomly.
Can anyone help me with this?

The exception is thrown because the file you are trying to move is open by your program or another process. Make sure that you are always closing the file after you finish processing it. Particularly, make sure that you always call Close or Dispose on all FileStream objects when they are no longer needed.
If the file is open by another process (for example by another user) then you can wait for some time and retry moving the file.

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.
