openfile dialog with folder and file filter for automatic processing

[abz89]

hi everybody, i'm a totally newbie in c#, i've create a little program just to read the .txt file

But how if i want to make a simple text reader takes a file from the folder using the same openfile dialog??

the components are :

1. open button -> openfile dialog
2. ok button -> execute
3. textbox -> display output

i want that the openfile dialog filter not only text file | *.txt but also can select a folder to batch the reading .txt process in current folder.

when the ok button pressed the program will:

1. if the selected is a single text file:

simply 'cat' the single text file to textbox output

if the selected is a folder:
will search any .txt in the folder then 'cat' the contents file to the textbox output

thx a lot! :D

Hi,
So first of all take a look at:
Create a Text Editor in 5 minutes. C# - magic.

Than for selecting a folder you should use FolderBrowserDi alog.

An example would be something like this:

 private void btnSelectFolder_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog fbd = new FolderBrowserDialog();

            fbd.ShowNewFolderButton = false;
            fbd.ShowDialog();

            var textualFiles = Directory.GetFiles(fbd.SelectedPath, "*.txt");

            if (textualFiles.Length > 0)
            {
                txtFileContent.Text = string.Empty;

                foreach (string fileTxt in textualFiles)
                {
                    _fileName = Path.Combine(fbd.SelectedPath, fileTxt);
                    LoadFolderContent();
                }
            }
        }

        private void LoadFolderContent()
        {
            try
            {
                TextReader tr = new StreamReader(_fileName);
                try
                { txtFileContent.Text += tr.ReadToEnd(); }
                catch (Exception ex)
                { MessageBox.Show(ex.Message); }
                finally
                { tr.Close(); }
            }
            catch (System.IO.FileNotFoundException ex)
            { MessageBox.Show("Sorry, the file does not exist."); }
            catch (System.UnauthorizedAccessException ex)
            { MessageBox.Show("Sorry, you lack sufficient privileges."); }
            catch (Exception ex)
            { MessageBox.Show(ex.Message); }
        }

And use foreach keyword to output all the text files at the same time.
