Hello Experts

Here is my connection string

and my store procedure is

SqlConnection objCon = new SqlConnection(con);
                objCon.Open();

                SqlCommand cmd = new SqlCommand("Studentinsertadmission", objCon);
  cmd.Parameters.Add(new SqlParameter("@Studentid",Convert.ToInt32( studentid.Text)));
                cmd.Parameters.Add(new SqlParameter("@StudentName", firstname.Text));
                cmd.Parameters.Add(new SqlParameter("@Image", image.image  ));


cmd.CommandType = CommandType.StoredProcedure;
                int rows = cmd.ExecuteNonQuery();
                objCon.Close();
                
                MessageBox.Show("Record Inserted Successfully! ");

Hi, check here.

Remember you have to get Byte array (byte[]) from picture to save it into a dataBase.

What is your DB table (table you wish to insert into) structure?

Anyway, here is my solution for you, I only didnt include sql and DB insertion.
(for it you have to use sql query:
@"INSERT INTO Table VALUE (@id, @picByte, @picName)"
- id
- pic byte[]
- pic name (string) - its optional, but its good to have it.

So heres the code:

string lastDir;
        string fileName;
        public Form1()
        {
            InitializeComponent();
        }

        private void buttonOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog open = new OpenFileDialog();
            open.Filter = "Image Files(*.png; *.jpg; *.bmp)|*.png; *.jpg; *.bmp";
            if (lastDir == null)            
                open.InitialDirectory = @"C:\";
            else
                open.InitialDirectory = lastDir;
            if (open.ShowDialog() == DialogResult.OK)
            {
                fileName = System.IO.Path.GetFullPath(open.FileName);
                lastDir = open.FileName;
                pictureBox1.Image = new Bitmap(open.FileName);
                this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.Zoom;
            }
        }

        private void buttonSave_Click(object sender, EventArgs e)
        {
            //get image:
            Image img = Image.FromFile(fileName);
            //get byte array from image:
            byte[] byteImg = ImageToByteArray(img);

            //here do the insertion into dataBase!
            //but remember, your field in DB must be type to byte array
        }

        public byte[] ImageToByteArray(Image img)
        {
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            return ms.ToArray();
        }

Ok, that you wont bother with insert query (even if you know it, or if you have a stored procedure), here is my full code:

string lastDir;
        string fileName;
        public Form1()
        {
            InitializeComponent();
        }

        private void buttonOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog open = new OpenFileDialog();
            open.Filter = "Image Files(*.png; *.jpg; *.bmp)|*.png; *.jpg; *.bmp";
            if (lastDir == null)            
                open.InitialDirectory = @"C:\";
            else
                open.InitialDirectory = lastDir;
            if (open.ShowDialog() == DialogResult.OK)
            {
                fileName = System.IO.Path.GetFullPath(open.FileName);
                lastDir = open.FileName;
                pictureBox1.Image = new Bitmap(open.FileName);
                this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.Zoom;
            }
        }

        private void buttonSave_Click(object sender, EventArgs e)
        {
            //get image:
            Image img = Image.FromFile(fileName);
            //get byte array from image:
            byte[] byteImg = ImageToByteArray(img);

            //here do the insertion into dataBase!
            //but remember, your field in DB must be type to byte array
            //example:
            using (SqlConnection sqlConn = new SqlConnection("connString"))
            {
                using (SqlCommand cmd = new SqlCommand())
                {
                    cmd.CommandText = @"INSERT INTO MyTable VALUES (@id, @image, @name)";
                    cmd.Connection = sqlConn;
                    sqlConn.Open();
                    try
                    {
                        cmd.ExecuteNonQuery();
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }
            }
        }

        public byte[] ImageToByteArray(Image img)
        {
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            return ms.ToArray();
        }
