I am facing a Problem with reading images from database

Question

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code... 
                string connect = "datasource = localhost; port = 3306; username = root; password = ;"; 
                MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
                MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
                MySqlDataReader reader; 
                try
                    conn.Open(); // Opening Connection
                    reader = sda.ExecuteReader(); // Executing my Query..
                    while (reader.Read())
                        byte[] imgg = (byte[])(reader["Picture"]);
                        if (imgg == null)
                            pc1.Image = null;
                        else
                            MemoryStream mstream = new MemoryStream(imgg);
                            pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches.  I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data.  The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data.  The solution usually is to use UTF8 encoding instead of the default ascii encoding. 
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.
