1. 将图片转为二进制存入数据库

      string road = Application.StartupPath;
            int index = road.LastIndexOf("bin");
            string roadsub = road.Substring(0, index);
            string roadNew = roadsub + "Resources\\Me.jpg";
            System.IO.FileStream fs = new System.IO.FileStream(roadNew, FileMode.OpenOrCreate,             FileAccess.Read);
            byte[] fileByte = new byte[fs.Length];
            fs.Read(fileByte, 0, (int)fs.Length);

            int j = -1;
            string sqlcommandText = @"insert into Picture (PContent)values(@pcontent)";
            j = SqlHelper.ExecuteNonQuery(sqlcommandText, new SqlParameter("@pcontent", SqlDbType.Image) { Value = fileByte});
