I'd be tempted to say "sod that" and cheat!
Is the order important?
If not, then create a List<String> of elements to make up your CSV data, and use the Linq Method .Distinct to remove duplicates. Then String.Join to bolt 'em together with commas.
string csv = string.Join("," myList.Distinct());

The order is not really important, I am starting the record process from scratch. Thanks I will give it a look.

If threads are causing your duplicate, you're in even bigger trouble, since you are also accessing a Control property, something only the GUI thread is allowed to do.
IMO your code needs a big overhaul: use a model that holds your data, a view that takes care of the UI, and a separate object (or at least an explicit method) to create the output file(s) you need.
By not mixing it all up you'll avoid both illegal cross-thread Control accesses and the risk of duplicates in your CSV.

I would more likely keep a Dictionary or something to hold the items to be written, you can add an item more than once and it'll just overwrite the existing value, then format and write it once everything is ready.
A small class could easily be written to encapsulate Add, Write, Clear functions.

I'll look into that! Thanks

Hi.
Lemme try to be clear here.
I've a code, with two files: Form1.cs and Classes.cs
Classes.cs contains all my methods, variables, etc (and the FilesystemWatcher implementation).
Form1.cs (The main form) contains some button calls, and a call to FilesystemWatcher (when the button is pressed).
What i'm trying to accomplish and can't see to figure out is: Show a ProgressBar from this FilesystemWatcher.
Consider the following scenario: I Just clicked a button and FilesystemWatcher has started. It will monitor the folder and do operations over created files. How i'm gonna show the progress for that ?
On my readfiles() method (inside the Classes.cs) i've tought about passing a variable trough parameter that indicates how much of the file has been read - for so i would have to implement FilesystemWatcher in the Form1.cs. But the FilesystemWatcher calls all my methods.
His method on Classes.cs looks like:
SetupFileWatcher()
all other methods to convert files, etc...
Even if i move FilesystemWatcher to Form1 main code, he doesn't return any progress value - he just run methods as soon files are added.
Lemme try to show a piece of code (This happens at Classes.cs)
Implementing filesystem watcher on this method...
protected FileSystemWatcher SetupFileWatcher(string path)
FileSystemWatcher Call
public void ProgramProcessing(string filePath)
{
SetupFileWatcher(SelectedFolder);
InputFolderSelect();
ReadFiles();
FileDefinition();
ColorExtraction();
ColorValueExtraction();
DataGrouping();
NumberProcessing();
ColorPoolManipulation();
WriteInkzoneXML();
WriteColorPoolXML();
}
Now, this happens inside Form1.cs:
private void btnGo_Click_1(object sender, EventArgs e)
prg.ProgramProcessing(textBox1.Text);
How could i possibly achieve that ? Is it possible ? Al i would like is to show the progress for the operation (or at least the methods for reading files and write XML).
Thanks in advance for any help\guidance.

Hi All,
I am trying to write console application using C# which can export IBM DB2 table data from master database and import same to IBM DB2 table in target database , provided both tables are not coming under same DB2 instance.
can someone please provide direction how to achieve this ?
I tried using DB2BulkCopy Class but not succeeded.
pls help
Thanks

Or you can hit it with a hammer - make a connection to DB1, query the data and store it somewhere.
Connect to DB2 and write each record into the target table from the temp store.
Definitely not elegant and may be unworkable with serious volume.
Explore setting up a linked server and creating a stored proc that can do the job without taking the data into your c# client.
There should also be the equivalent of SQL Servers DTS ETL tools!
Never underestimate the power of human stupidity

Probably the easiest way for you to do this would be for your windows application to loop around and check to see if there are any new events. You would have to do this on a background thread.

Just to add to what Pete says, you also need to look at site scraping to extract teh data you are interested in.
A simple google should help with that: site scraping c# - Google Search[^]

I am learning C# or others...
Can anybody tell me. WHere can i download the source code that is writen in the book that I have.
For example the book
1. Pro C# 5.0 and the .NET 4.5 Framework
or
2. Beginning Csharp Object-Oriented Programming 2nd Edition

When I google Beginning Csharp Object-Oriented Programming 2nd Edition one of the top results tells me where the source code is made available; and I expect so does the books preface.

What, for both of them? That's very clumsy of him...
Have you considered contacting the publishers and see if they have spares they could send you? They may ask for the front or back cover to ensure you have the "real thing" and didn't pirate an epub or mobi copy off the internet.
