asp. net Two Ways to Output Pictures in Binary Stream

This paper describes two methods of asp. net to realize the output of pictures in binary stream. Share it for your reference, as follows:

Method 1:

System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.Stream str = new FileUpload().PostedFile.InputStream;
System.Drawing.Bitmap map = new System.Drawing.Bitmap(str);
map.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
Response.ClearContent();
Response.ContentType = "image/gif";
Response.BinaryWrite(ms.ToArray());

Method 2:

System.IO.FileStream fs = new System.IO.FileStream("Filename", System.IO.FileMode.Open, System.IO.FileAccess.Read);
byte[] datas = new byte[fs.Length];
fs.Read(datas, 0, Convert.ToInt32(fs.Length));
fs.Close();
Response.OutputStream.Write(datas,0,Convert.ToInt32(fs.Length));
Response.End();

I hope this article is helpful to everyone's asp. net programming.
