Przycisk zapisujący plik z zasobów na pulpit

Question

Witam

Mam taki kod:

        private void Button2_Click(object sender, EventArgs e)
        {
            Assembly assembly = Assembly.GetExecutingAssembly();

            using (Stream resourceStream = assembly.GetManifestResourceStream("Resources.example.txt"))

            {
                if (resourceStream != null)
                {
                    string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

                    string filePath = Path.Combine(desktopPath, "example.txt");

                    using (FileStream fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write))

                    {
                        resourceStream.CopyTo(fileStream);
                    }

                }
            }
        }

Powinien on zapisać plik example.txt z zasobów na pulpit, a tego nie robi. Proszę o pomoc

Answer 1

Może pobierz zawartość pliku example.txt z zasobów i zapisz zawartość

        private void button2_Click(object sender, EventArgs e)
        {
            string content = Properties.Resources.example;

            if (content != null)
            {
                string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
                string filePath = Path.Combine(desktopPath, "example.txt");
                using (StreamWriter writer = new StreamWriter(filePath))
                {
                    writer.Write(content);
                }
            }
        }

a co w przypadku np. pliku rar lub exe?

---

możesz użyć np. "tablicy  bajtów"

byte[] content = Properties.Resources.example;

 

private void button1_Click(object sender, EventArgs e)
{
    string content = Properties.Resources.example;

    if (content != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "example.txt");
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            writer.Write(content);
        }
    }
}

private void button2_Click(object sender, EventArgs e)
{
    byte[] content = Properties.Resources.zip_example;

    if (content != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "zip_example.zip");
        File.WriteAllBytes(filePath, content);
    }
}

private void button3_Click(object sender, EventArgs e)
{
    byte[] content = Properties.Resources.exe_example;

    if (content != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "exe_example.exe");
        File.WriteAllBytes(filePath, content);
    }
}

 

 

BTW,

private void button3_Click(object sender, EventArgs e)
{
    if (Properties.Resources.exe_example != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "exe_example.exe");
        File.WriteAllBytes(filePath, Properties.Resources.exe_example);
    }
}

 

W przypadku obrazka (pliki typu System.Drawing.Bitmap) należy najpierw przekonwertować go na tablicę bajtów, można użyć do tego np. MemoryStream (można też ImageConverter.ConvertTo)

private void button4_Click(object sender, EventArgs e)
{
    if (Properties.Resources.robot_blue != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "robot_blue.jpg");

        using (MemoryStream stream = new MemoryStream())
        {
            Properties.Resources.robot_blue.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
            File.WriteAllBytes(filePath, stream.ToArray());
        }

        pictureBox1.Image = Properties.Resources.robot_blue;
    }
}

    if (Properties.Resources.robot_blue != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "robot_blue.jpg");

        // using System.Drawing;
        Bitmap image = Properties.Resources.robot_blue;
        // Konwertuj obrazek na tablicę bajtów
        ImageConverter converter = new ImageConverter();
        byte[] content = (byte[]) converter.ConvertTo(image, typeof(byte[]));
        File.WriteAllBytes(filePath, content);
    }

lub przez użycie metody Save klasy Image

    if (Properties.Resources.robot_blue != null)
    {
        string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        string filePath = Path.Combine(desktopPath, "robot_blue.jpg");

        // using System.Drawing.Imaging
        Image content = Properties.Resources.robot_blue;
        content.Save(filePath, ImageFormat.Jpeg);
    }
