Thanks first for your help. Please can you really tell me what i should use instead Directory.EnumerateFileSystemEntries so that it can count how much csv file are contained in zip file?

ok it's done. Thanks

I wanted to program a message that tells me if there is one or more cvs file present in the zip file and gives me the number of files contained in this zip. Is not that possible? i tried this:
var = comboBox1.SelectedItem.ToString();
fullpath = fbd.SelectedPath + "\\"+ var;

comboBox2.Items.Clear();
if (File.Exists(fullpath))
{
ZipArchive zip = ZipFile.OpenRead(fullpath);
MessageBox.Show(Directory.EnumerateFileSystemEntries(fullpath, "*.csv").ToList<string>().Count + " csv file(s) present"); // get error here
foreach (ZipArchiveEntry entry in zip.Entries)
{
comboBox2.Items.Add(entry.FullName); // fill comboBox2 with *.csv files from selected zip file
}
zip.Dispose();
}
else
{
MessageBox.Show("no csv file(s) present");
}

Hello,
how can i check the contents of zip file before read it? i tried with File.Exist(fullpath), but no check is done. fullpath contains the directory and the zip filename. thank for your time

Morning Maciej and thank you for help. I can't close the zip file however a tried to close zipfile or zip. I get an error like:"string or ZipArchive does not contain a definition for 'close' and no extension method 'close' accepting a first argument of type string or ZipArchive could be found." This is all the code in the method, you can maybe find why is not working. Thank again!!!

My Code:
private void button1_Click_1(object sender, EventArgs e)
{
// Create an Instance of FolderBrowserDialog Class
OpenFileDialog ofd = new OpenFileDialog();

// Set an Initial SelectedPath property
ofd.InitialDirectory = @"\\servername";
string filter = "*.zip";

// Show the OpenFileDialog.
DialogResult result = ofd.ShowDialog();
if (result == DialogResult.OK)
{
string fullPath = ofd.FileName;
string directory;
directory = fullPath.Substring(0, fullPath.LastIndexOf('\\'));

// Write the Selectedpath to the TextBox nearby the Button
textBox1.Text = directory;

if (File.Exists(fullPath))
{
List<string> files = Directory.EnumerateFiles(directory, filter, SearchOption.AllDirectories)
.Where(x => File.GetLastWriteTime(x) >= startDate && File.GetLastWriteTime(x) <= endDate)
.Select(x => Path.GetFileName(x))
.ToList();

comboBox1.Items.Clear();
foreach (string zipfile in files)
{
this.comboBox1.Items.Add(zipfile); // fill cbx1 with *.zip files
// zipfile.Close(); cuz not working
}

comboBox2.Items.Clear();
ZipArchive zip = ZipFile.OpenRead(fullPath);
foreach (ZipArchiveEntry entry in zip.Entries)
{
comboBox2.Items.Add(entry.FullName); // fill cbx2 with *.csv files
// zip.Close(); also not working
}
}
}
}

This works, but only for the first selected filename! So when I select another zip file in my combobox1, my code does not populate the combobox2 with the elements of the newly selected file. It is always the same data in combobox2. How do I change my code to work? Thanks

Thank you very much, it works very well !!! And how can I fill a new combobox2 with the entries of each zipfile? I mean, I select a zip file in my combobox1, its entries like test.txt will appear in the combobox2 and the entries of that test.txt will also appear in a datagridview as a table. How can I do that in the same code?
i've tried this to populate the new combobox2, but it's not working. I get an error and have to break the code when it run. concerning the datagridview i don't have idea.
ZipArchive zip = ZipFile.OpenRead(directory);
foreach (ZipArchiveEntry entry in zip.Entries)
{
comboBox2.Items.Add(entry.FullName);
}
It would be very nice to help me one last time.
thanks again an all

It's done! should l made it in the code behind of the DateTimePicker Control or in the Button Control where i write all this code? I made it in the code behind of the DateTimePicker Control but i'm not sure. Thanks a lot.

Hey,
Many thanks!!! It works for the zip file, but is it possible to leave the choice to the user to enter his own date range whenever he needs it using the DateTimePicker Control on my Forms(Interface)? In addition I also want to be able to enter the exact time of the chosen date. That what i've tried does not work.
Any ideas? Thank you in advance.

Hi Dora and thank you for your answer.
i've try it but the name of my DataGrid is not recognized by my ViewModel class. it Show me a error message like that:"DG is not present in this context"

thank you!!!
I could not ask like other it the reason why I have done so

is it another way to solve it? i can't use the code-Behind to do this
