Question

The following code prompts the user to select a path to save an image from the pictureBox:

        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();            
        saveFileDialog1.Filter = "Portable Network Graphics|*.png";
        saveFileDialog1.Title = "Bild speichern";
        saveFileDialog1.RestoreDirectory = true;
        saveFileDialog1.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {
                this.picBox.Image.Save(myStream.ToString()); // is not getting the selected path
                myStream.Close();
            }
        }

But how can I get the path from myStream or save the image to the user defined location (with compatibility to .NET 3.5)?

If you want to get the selected file path from the save dialog then use…

saveFileDialog1.FileName;

See here for more information on this property

You don’t need to worry about using a Stream for this task.

Just to be clear, here is what your code should be…

SaveFileDialog saveFileDialog1 = new SaveFileDialog();            
saveFileDialog1.Filter = "Portable Network Graphics|*.png";
saveFileDialog1.Title = "Bild speichern";
saveFileDialog1.RestoreDirectory = true;
saveFileDialog1.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
    this.picBox.Image.Save(saveFileDialog1.FileName);
}
