Please refer to this example, which demonstrates (*.txt), but you can modify according to your needs: http://msdn.microsoft.com/en-us/library/system.windows.forms.openfiledialog.aspx

first thanks DdoubleD for your reply, but this's not what I want.
When I change the filter/extension of openFileDialog such as "All files" to ".txt" the dialog should showing any .txt files only, but that's not what happens.

So, how could I achieve this???

Thanks

You will always see the directories in the directory you are in with OpenFileDialog. And if you don't see any *.txt files that could be because there are no *.txt files in that specific directory.

So, do you know how to display files only without showing directories ???

Thanks

Its not possible with the OpenFileDialog. You would probably need to roll your own control. A simple form with a listbox would do(see attached image).
Code:

public partial class FileDialog : Form
    {
        public FileDialog()
        {
            InitializeComponent();
        }

        private void FileDialog_Load(object sender, EventArgs e)
        {
            //directory to retrieve files from
            const string  DirPath = @"C:\Users\Dan\Documents";

            //get files
            string[] files = Directory.GetFiles(DirPath, "*.txt", SearchOption.TopDirectoryOnly);
            
            //display filenames in listbox
            foreach (string file in files)
            {
                ListFile lf = new ListFile { Path = file };
                lstFiles.Items.Add(lf);
            }
        }

        //struct to store file in listbox
        private struct ListFile
        {
            //path store full file path
            public string Path {get;set;}

            //to string returns just file name for display
            public override string ToString()
            {
                return Path.Substring(Path.LastIndexOf(@"\") + 1);
            }
        }

        //store selected file path
        public string selectedFile { get; set; }

        private void btnOpen_Click(object sender, EventArgs e)
        {
            //if file selected
            if (lstFiles.SelectedIndex >= 0)
            {
                //store path
                selectedFile = ((ListFile)lstFiles.SelectedItem).Path;

                //Set dialog result and hide form
                this.DialogResult = DialogResult.OK;
                this.Hide();
            }
            else
            {
                MessageBox.Show("Please select a file", "No File Selected");
            }
        }

        private void btnCancel_Click(object sender, EventArgs e)
        {
            //set empty path and dialog result
            selectedFile = string.Empty;
            this.DialogResult = DialogResult.Cancel;
        }
    }

How to use:

FileDialog dialog = new FileDialog();
            if (dialog.ShowDialog() == DialogResult.OK)
            {
                MessageBox.Show("Selected File: " + dialog.selectedFile);
            }
            dialog.Dispose();
