I am not sure how to do a menu that works so it serialize my object.
(the menu is created so it how it all should be working I cant get to work correct)

Please check my code below and tell me how to do it correct.

What I like is to take my object and be able to save it, Save As, Open it and create a new.
private void newToolStripMenuItem_Click(object sender, EventArgs e)
        {
 
        }
 
        private void openToolStripMenuItem_Click(object sender, EventArgs e)
        {
            string nameOfFile = "";
            OpenFileDialog openExtensFile = new OpenFileDialog();
            openExtensFile.Title = "C#";
            openExtensFile.InitialDirectory = @"c:\";
            openExtensFile.Filter = "All files (*.*)|*.*|All files (*.*)|*.*";
            openExtensFile.FilterIndex = 2;
            openExtensFile.RestoreDirectory = true;
            if (openExtensFile.ShowDialog() == DialogResult.OK)
            {
                //nameOfFile = fdlg.FileName ; 
            } 
        }
 
        private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
        {
            SaveFileDialog saveFileDialog1 = new SaveFileDialog(); 
            saveFileDialog1.InitialDirectory = Convert.ToString(Environment.SpecialFolder.MyDocuments); 
            saveFileDialog1.Filter = "Your extension here (*.EXT)|*.ext|All Files (*.*)|*.*" ; 
            saveFileDialog1.FilterIndex = 1; if(saveFileDialog1.ShowDialog() == DialogResult.OK) 
            {         
                Console.WriteLine(saveFileDialog1.FileName);//Do what you want here
                //this.textBox1.Text = saveFileDialog.FileName;
            }
        }
 
        private void exportToXMLToolStripMenuItem_Click(object sender, EventArgs e)
        {
 
        }

            //binaryArraySerialize(obj);
 
 
        }
 
 
        public static void binaryFileSerialize(Object obj, string filePath)
        {
            FileStream fileStream = null;
            
             
            try
            {
                fileStream = new FileStream(filePath,  FileMode.Create);
                BinaryFormatter b =  new BinaryFormatter();
                b.Serialize(fileStream, obj);
            }
 
            catch

                    throw new FileNotFoundException("The file" + " was not found. ", filePath);
 
                fileStream = new FileStream(filePath, FileMode. Open);

            ms.Seek(0, 0);
            serializedObject = ms.ToArray();
            ms.Close();
            return serializedObject;
        }

            ms.Seek(0, 0);
            BinaryFormatter b = new BinaryFormatter();
            Object obj = b.Deserialize(ms);
            ms.Close();
            return (T)obj;
