本文实例讲述了asp.net实现图片以二进制流输出的两种方法。分享给大家供大家参考，具体如下：

方法一：

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());

方法二:

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();

希望本文所述对大家asp.net程序设计有所帮助。
