本文實例講述了asp.net實現圖片以二進制流輸出的兩種方法。分享給大家供大家參考，具體如下：
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(); |
希望本文所述對大家asp.net程序設計有所幫助。
