怎么用c#写一个把数据转换成图片的代码呢？

Question

高手可以给出关键代码么？

Answer 1

你说的是二进制转图片吧
        public static Image BytesToImage(byte[] pictureData)
        {
            Image img = null;
            if (pictureData != null && pictureData.Length > 0)
            {
                using (MemoryStream stream = new MemoryStream(pictureData))
                {
                    img = Image.FromStream(stream);
                }
            }
            return img;
        }

Answer 3

string SqlStr = string.Format("select * from XX where ID='{0}'", ID);
            SqlDataReader dr = SqlHelper.ExecuteReader("连接字符串", CommandType.Text, SqlStr);            AudioFileModel afm = new AudioFileModel();
            if (dr.Read())            {
                byte[] test = (byte[])dr["AudioFileStream"];
            }然后结合1L的函数 即可
