Check if a folder exists with only a part of the name in C#

I have created a code to create folders with two Textboxes.
Textbox1 - customer number (XXXX).
Textbox2 - customer name.
I would like to be able to check if the customer number exists before creating the folder.
The newly created folder will be the combination of the two Textboxes (this is already solved).
I just need to be able to determine if the folder exists only with the customer number, as it is probably created with (customer number + customer name).
Current working code:
{
string no = textBox1.Text;
string client = textBox2.Text;
string carpeta = #"C:\" + no + " " + client;
string sourcePath = #"C:\main";
string destinationPath = #"C:\" + no + " " + client;
textBox1.Clear();
textBox2.Clear();
try
{
if (Directory.Exists(carpeta))
{
DialogResult y;
y = MessageBox.Show("Folder already exists\nDo you want to open it?", "AE.", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);
if (y == DialogResult.Yes)
{
System.Diagnostics.Process.Start(#"C:\" + no + " " + client);
}
else
{
Close();
}
}
else
{
DialogResult x;
x = MessageBox.Show("The folder doesn't exist\nWant to create a folder?." + "\n" + no + " " + client, "AE.", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
if (x == DialogResult.Yes)
{
Directory.CreateDirectory(carpeta);
FileSystem.CopyDirectory(sourcePath, destinationPath, UIOption.AllDialogs);
System.Diagnostics.Process.Start(#"C:\" + no + " " + client);
}
else
{
Close();
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error:" + ex.Message);
}
}

You could also each time you need the folder just do that:
public static void Main()
{
var username = "someuser";
var usernumber = "ABC123";
var mainDirectory = #"C:\Path\To\The\Main\Dir";
var pathToTheUserDirectory = Path.Combine(mainDirectory, $"{username}-{usernumber}");
// This line will create the directory if not exist or take the existing directory.
var directoryInfo = Directory.CreateDirectory(pathToTheUserDirectory);
var directoryPath = directoryInfo.FullName;
// ...
// or
// directoryInfo.Delete(recursive: true);
}

string[] dirs = Directory.GetDirectories(#"c:\", txtTextBox.Text + "*");
this will only get directrories starting with the desired Text
Edit: This is only a good solution if the customer number has fixed places (in you exaple 4 from 0000-9999)

Copying a file that is a virus caused my program to terminate

I have made a tool that will copy files from a source to a destination. However during the copy, the software came across a virus that was flagged by the anti-virus software (Symantec).
The anti-virus then caused my software to close down, and quarantine the program as a "dropper".
Is there anyway I can gracefully handle this scenario, rather than shutting down my program completely?
I appreciate that the action was the result of the anti-virus, but is there anything I can do to help the situation? For example, Robocopy does not just terminate when it comes across a virus.
Here is my copy code;
void CopyFileExactly(CopyParameterBundle cpb, bool overwrite)
{
string CTP = "", CFP = "";
CFP = cpb.SourcePath;
if (cpb.RenameFile)
CTP = cpb.DestPath ;
else
CTP = cpb.DestPath;
//Check firstly if the file to copy exists
if (!File.Exists(CFP))
{
throw new FileNotFoundException();
}
//Check if destination file exists
//If it does, make it not read only so we can update MAC times
if (File.Exists(CTP))
{
var target = GetFile(CTP);//new FileInfo(CTP);
if (target.IsReadOnly)
target.IsReadOnly = false;
}
var origin = GetFile(CFP);//new FileInfo(CFP);
GetFile(CTP).Directory.Create();
//(new FileInfo(CTP)).Directory.Create();
origin.CopyTo(CTP, (overwrite ? true : false));
if (!File.Exists(CTP))
{
throw new FileNotFoundException("Destination file not found!");
}
var destination = GetFile(CTP);//new FileInfo(CTP);
if (destination.IsReadOnly)
{
destination.IsReadOnly = false;
destination.CreationTime = origin.CreationTime;
destination.LastWriteTime = origin.LastWriteTime;
destination.LastAccessTime = origin.LastAccessTime;
destination.IsReadOnly = true;
}
else
{
destination.CreationTime = origin.CreationTime;
destination.LastWriteTime = origin.LastWriteTime;
destination.LastAccessTime = origin.LastAccessTime;
}
if (performMD5Check)
{
var md5Check = compareFileMD5(CFP, CTP);
cpb.srcMD5Hash = md5Check.Item2;
cpb.dstMD5Hash = md5Check.Item3;
if (!md5Check.Item1)
throw new MD5MismatchException("MD5 Hashes do NOT match!");
}
}
The calling code;
void BeginCopy(int DegreeOfParallelism, int retryCount, int retryDelay)
{
object _lock;
//Setup cancellation token
po.CancellationToken = cts.Token;
//Set max number of threads
po.MaxDegreeOfParallelism = DegreeOfParallelism;
//Exceptio logging queue
var exceptions = new ConcurrentQueue<Exception>();
var completeItems = new ConcurrentQueue<CopyParameterBundle>();
var erroredItems = new ConcurrentQueue<CopyParameterBundle>();
//Logger logger = new Logger(sLogPath);
//logger.Write("Starting copy");
Task.Factory.StartNew(() =>
{
Parallel.ForEach(CopyParameters,
po,
(i, loopState, localSum) =>
{
localSum = retryCount;
do
{
try
{
//Go off and attempt to copy the file
DoWork(i);
//Incrememt total count by 1 if successfull
i.copyResults.TransferTime = DateTime.Now;
i.copyResults.TransferComplete = true;
completeItems.Enqueue(i);
//logger.Write("Copied file from: " + i.SourcePath + "\\" + i.SourceFile + " => " + i.DestPath + "\\" + i.SourceFile);
break;
}
catch (Exception ex)
{
//this.richTextBox1.AppendText("[-] Exception on: " + i.SourcePath + "\\" + i.SourceFile + " => " + ex.Message.ToString() + System.Environment.NewLine);
//Exception was thrown when attempting to copy file
if (localSum == 0)
{
//Given up attempting to copy. Log exception in exception queue
exceptions.Enqueue(ex);
this.SetErrorText(exceptions.Count());
//Write the error to the screen
this.Invoke((MethodInvoker)delegate
{
this.richTextBox1.AppendText("[-] Exception on: " + i.SourcePath + "\\" + i.SourceFile + " => " + ex.Message.ToString() + System.Environment.NewLine);
i.copyResults.TransferComplete = false;
i.copyResults.TransferTime = DateTime.Now;
i.copyResults.exceptionMsg = ex;
erroredItems.Enqueue(i);
//logger.Write("ERROR COPYING FILE FROM : " + i.SourcePath + "\\" + i.SourceFile + " => " + i.DestPath + "\\" + i.SourceFile + " => " + ex.Message.ToString() + " => " + ex.Source);
});
}
//Sleep for specified time before trying again
Thread.Sleep(retryDelay);
localSum--;
}
//Attempt to Repeat X times
} while (localSum >= 0);
//Check cancellation token
po.CancellationToken.ThrowIfCancellationRequested();
Interlocked.Increment(ref TotalProcessed);
this.SetProcessedText(TotalProcessed);
//Update Progress Bar
this.Invoke((MethodInvoker)delegate
{
this.progressBar1.Value = (TotalProcessed);
});
});
//aTimer.Stop();
this.Invoke((MethodInvoker)delegate
{
this.label9.Text = "Process: Writing Log";
});
WriteLog(sLogPath, completeItems, erroredItems);
this.Invoke((MethodInvoker)delegate
{
this.label9.Text = "Process: Done!";
});
if (exceptions.Count == 0)
MessageBox.Show("Done!");
else
MessageBox.Show("Done with errors!");
EnableDisableButton(this.button2, true);
EnableDisableButton(this.button4, false);
});
}

What happened is most likely that the antivirus was aware of the virus file, so when it detected that a change in the file system (moving the file) occurred, it terminated the program because by moving the virus to a different location in your computer, it could cause problems (since it's a virus). It was flagged as dropper, basically a type of program that is designed to install the virus.
Edit: i forgot to mention that to solve the problem you will most likely need to license your program.

System.Net.WebException while downloading file

I have a list of mp3 which I am downloading. After some files are downloaded, not all of them - around 5-7, I get WebException. I did a stacktrace and this is the result.
Exception thrown: 'System.Net.WebException' in System.dll
Debug message: The operation has timed out
InnerEx: at System.Net.HttpWebRequest.GetResponse()
at iBlock.Main._InetGetHTMLSearch(String sArtist) in C:\Users\...\Main.cs:line 590
My _InetGetHTMLSearch looks like this
private void _InetGetHTMLSearch(string sArtist)
{
aLinks.Clear();
if (AudioDumpQuery == string.Empty)
{
//return string.Empty;
}
string[] sStringArray;
string sResearchURL = "http://www.audiodump.biz/music.html?" + AudioDumpQuery + sArtist.Replace(" ", "+");
string aRet;
HttpWebRequest webReq = (HttpWebRequest)HttpWebRequest.Create(sResearchURL);
webReq.UserAgent = "Mozilla / 5.0(Macintosh; Intel Mac OS X 10_9_3) AppleWebKit / 537.75.14(KHTML, like Gecko) Version / 7.0.3 Safari / 7046A194A";
webReq.Referer = "http://www.audiodump.com/";
webReq.Timeout = 5000;
try
{
webReq.CookieContainer = new CookieContainer();
webReq.Method = "GET";
using (WebResponse response = webReq.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
aRet = reader.ReadToEnd();
//Console.WriteLine(aRet);
string[] aTable = _StringBetween(aRet, "<BR><table", "table><BR>", RegexOptions.Singleline);
if (aTable != null)
{
string[] aInfos = _StringBetween(aTable[0], ". <a href=\"", "<a href=\"");
if (aInfos != null)
{
for (int i = 0; i < aInfos.Length; i++)
{
//do some magic here
}
}
else
{
//debug
}
}
else
{
//debug 2
}
}
response.Dispose();
}
}
catch (Exception ex)
{
Console.WriteLine("Debug message: " + ex.Message + "InnerEx: " + ex.StackTrace);
aLinks.Clear();
return;
//throw exception
}
}
what this method does is simple. A simple search of the sArtist given at audiodump.com
I have a timer which runs very fast, every 10ms.
private void MainTimer_Tick(object sender, EventArgs e)
{
_DoDownload(DoubleDimList[i][y], ref mp3ToPlay);
if (muted) Mute(0);
if (Downloading)
{
StatusLabel.Text = "Downloading: " + DoubleDimList[i][y];
}
}
Now this timer handles the download in the background in a Global scope.
The _DoDownload methos which basically starts the entire process looks like this
private void _DoDownload(string dArtist, ref string dPath)
{
if (!Contain && skip <= 3 && !Downloading)
{
try
{
_InetGetHTMLSearch(dArtist);
if (aLinks.Count < 1)
{
//skip and return
Console.WriteLine("Skipping: " + dArtist);
IniWriteValue(_playlists[i], "Track " + y, dArtist + " -iBlockSkip");
y++;
return;
}
string path = mp3Path + "\\" + dArtist + ".mp3";
if (DownloadOne(aLinks[0], path, false))
{
hTimmer.Start();
Downloading = true;
}
}
catch (Exception Ex)
{
MessageBox.Show("Download start error: " + Ex.Message);
}
}
else if (Downloading)
{
try {
int actualBytes = strm.Read(barr, 0, arrSize);
fs.Write(barr, 0, actualBytes);
bytesCounter += actualBytes;
double percent = 0d;
if (fileLength > 0)
percent =
100.0d * bytesCounter /
(preloadedLength + fileLength);
label1.Text = Math.Round(percent) + "%";
if (Math.Round(percent) >= 100)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
label1.Text = "";
dPath = path;
aLinks.Clear();
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
lastArtistName = "N/A";
Downloading = false;
y++;
if (y >= DoubleDimList[i].Count)
{
i++;
}
}
if (Math.Round(percent) <= 1)
{
if (hTimmer.ElapsedMilliseconds >= 3000)
{
string path = mp3Path + "\\" + dArtist + ".mp3";
hTimmer.Stop();
hTimmer.Reset();
fs.Flush();
fs.Close();
System.IO.File.Delete(path);
Contain = false;
skip += 1;
Downloading = false;
}
} }
catch(Exception Ex)
{
MessageBox.Show("Downloading error: " + Ex.Message);
}
}
}
Now once the exception is thrown it messes up the entire project. As you see in the last method, if _InetGetHTMLSearch doesn't update the search(returns nothing) I am skipping and moving to next search. However the exception will be thrown in every next search. I tried setting new cookies in every search but still didn't work.
Any solutions how to avoid this issue?
P.S. I have to say that if I change the timer's Interval to 500ms it will download more mp3 before the exception is thrown but not all of them.
Edit: The issue here is obvious. The request timesout but even if I set it to Timeout.Infinite it will hand there forever

Deleting files inside folder in C#

I am creating application to delete files for more than 15 days in past, I've created a project using the C# language "multithreading" to be able to delete these files, but its only reading the first file with the error

FileWatcher issue

OK, so this time I created a service with a file watcher to process file once created.
it seems that my service crashes when the files being processed reaches 1000 (I'm receiving loads of messages).
here is my logic: files comes in, file watcher read the text send it to email, insert into DB, move original message to a folders.
on the service start, I'm processing pending messages first before start to watch (I'm talking about over 1000 of text file pending) and my service needs about a second to work on each file.
All goes OK, but when the total incoming files reaches 1000, it simply crash.
sometimes the service stops processing pending and only start looking for new files only.
I have the "InternalBufferSize = 64000" the max recommended.
Please help me with my code (I know it should be multi-threaded for better handling, but I'm not that expert):

I wanted to add this as a comment but it exceeded the allowed number of characters so here goes.
First thing I noticed in your code that you are doing all the file handling inside the Created event handler. This is not a good practice, you should always let your FileSystemWatcher event handlers do minimum work as it might result an overflow which is probably what you are facing.
Instead it is better to delegate the work on a separate thread. You can add the events to a queue and let a background thread worry handling them. You can filter the files in the event handler so that your queue does not get filled with garbage.
Using Sleep inside the event handler is also considered a bad practice as you'll be blocking the FileSystemWatcher event.
The maximum buffer size allowed is 64K, it is not a recommended buffer size unless you are dealing with long paths. Increasing buffer size is expensive, because it comes from non-paged memory that cannot be swapped out to disk, so keep the buffer as small as possible. To avoid a buffer overflow, use the NotifyFilter and IncludeSubdirectories properties to filter out unwanted change notifications.
And finally I would suggest reading the FileSystemWatcher MSDN article and looking at several examples online before attempting to write code as the Windows watcher is somewhat delicate and prone to errors
