Getting exception while inserting image in access database

Question

I am trying to insert an image to access database through my C# application. But every time I am getting exception

 

Here is my code:

private void button1_Click(object sender, EventArgs e)

{

try

{

connection.Open();

string str = "INSERT INTO imageInsertRetrieve (FirstName,LastName,Image) values ('" + textBox1.Text + "','" + textBox2.Text + "',(@img))";

cmd = new OleDbCommand(str, connection);

ms = new MemoryStream();

pictureBox1.Image.Save(ms, ImageFormat.Jpeg);

byte[] photo_aray = new byte[ms.Length];

ms.Position = 0;

ms.Read(photo_aray, 0, photo_aray.Length);

cmd.Parameters.AddWithValue("@img", photo_aray);

cmd.ExecuteNonQuery();

}

catch(Exception exp)

{

MessageBox.Show(exp.ToString());

}

finally

{

connection.Close();

}

}
