Read / Write Image into SQL Server in ASP.NET Part - 1

  Then in Button Click event Write below lines of code

  int contentLength = File1.PostedFile.ContentLength;
    byte[] bytePic = new byte[contentLength];
    File1.PostedFile.InputStream.Read (bytePic, 0, contentLength); // File1 Is fileUpload control

   SqlConnection myConn = new SqlConnection (@"server=Myserver;database=MyDB;uid=sa;pwd=sa");
    try
    {
        connection.Open ();
        SqlCommand cmd = new SqlCommand ("insert into ImageTable (pic) values (@pic)", myConn);
        cmd.Parameters.Add ("@pic", BytePic);
        cmd.ExecuteNonQuery ();
    }
    catch(Exception ex)
   {
       throw ex;
   }
    finally
    {
        connection.Close ();
    }
