TextWriter Class – .NET – Fórum – Programujte.com

Ahojte, mám takýto kód:

public void ClickOnVypisText(object sender, RoutedEventArgs e)

        {

            string cesta = Subor.Text;

            string text = Text.Text;

            TextWriter stringWriter = new StringWriter();

            using (TextWriter streamWriter = new StreamWriter(cesta))

            {

                streamWriter.WriteLine(text);

            }

            Environment.Exit(1);

To w3q :

using (TextWriter streamWriter = new StreamWriter(cesta, true))

            {

                streamWriter.WriteLine(text);

            }

Vďaka to true mi chýbalo.

Mám ešte jeden problém, to true bežalo perfektne, ale keď som začal písať jednoduchý textový editor(moja napodobenina notepadu) tak mi to hádže chybu. Neviem či to je tým, že používam aj OpenFileDialog, resp. SaveFileDialog, ale prste to hádže chybu.

        private void uložiťToolStripMenuItem_Click(object sender, EventArgs e)

        {

            Stream cesta;

            string textik2 = richTextBox1.Text;

            SaveFileDialog savefiledialog1 = new SaveFileDialog();

            savefiledialog1.InitialDirectory = "C:\\";

            savefiledialog1.RestoreDirectory = true;

            savefiledialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";

            if (savefiledialog1.ShowDialog() == DialogResult.OK)

            {

                cesta = savefiledialog1.OpenFile();

                using (TextWriter streamWriter = new StreamWriter(cesta, true))

                {

                    streamWriter.WriteLine(textik2);

                }

            }



        }

Ahoj, pouzivas spatnou pretizenou metodu... resp. spatne je prvni parametr konstruktoru... aby ti to fungovalo jakko v minulym pripade musi byt "cesta" string a ne Stream.

Ja debil, písalo mi to už pri inej metode a tam som to opravil, a tu ma to nenapadlo :smile12: No aj tak, ďakujem.
