Save file to a specific folder in Windows Form C#

Question

I am trying to save some selected file in a folder(images) inside my application

I am able to get the file using following code:

         private void button1_Click(object sender, EventArgs e)
    {

        string imagelocation = "";

        OpenFileDialog dialog = new OpenFileDialog();

        if(dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK )
        {
            textBox2.Text = dialog.FileName;
        }
    }

For saving the file I got in textBox2, I tried following code. But with following code I have to also select the path where I want to save the file. What If I want to (set my path permanently to 'images' folder as shown in pic) for saving?

       private void button2_Click(object sender, EventArgs e)
    {


        SaveFileDialog f = new SaveFileDialog();

        if(f.ShowDialog() == DialogResult.OK)
        {
            using(Stream s = File.Open(f.FileName, FileMode.CreateNew))
            using(StreamWriter sw =  new StreamWriter(s))
            {
                sw.Write(textBox2.Text);
            }
        }
     }

2 Approaches to Solve this problem

• First Approach: (Browser the File and click Save, to automatically save the selected file to Image Directory)

    private void button2_Click(object sender, System.EventArgs e)
    {

        var assemblyPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
        var assemblyParentPath = Path.GetDirectoryName(assemblyPath);
        var imageDir = Path.Combine(assemblyParentPath, "Image");

        if (!Directory.Exists(imageDir))
            Directory.CreateDirectory(imageDir);


         using (Stream s = File.Open(imageDir+"\\"+Path.GetFileName(textBox1.Text), FileMode.CreateNew))
         using (StreamWriter sw = new StreamWriter(s))
         {
                     sw.Write(textBox1.Text);
         }

     }

• Second Approach: (Browser the File and Save Opens SaveDialog with Directory as Image Directory and File name as Previously selected File)

private void button2_Click(object sender, System.EventArgs e)
        {

            var assemblyPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
            var assemblyParentPath = Path.GetDirectoryName(assemblyPath);
            var imageDir = Path.Combine(assemblyParentPath, "Image");

            if (!Directory.Exists(imageDir))
                Directory.CreateDirectory(imageDir);

            SaveFileDialog f = new SaveFileDialog();
            f.InitialDirectory = imageDir;
            f.FileName = textBox1.Text;
            if (f.ShowDialog() == DialogResult.OK)
            {
                using (Stream s = File.Open(imageDir + "\\" + Path.GetFileName(textBox1.Text), FileMode.CreateNew))
                using (StreamWriter sw = new StreamWriter(s))
                {
                    sw.Write(textBox1.Text);
                }

            }
        }```
