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:
1

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。
