MemoryStream中的图片怎么保存到文件中去.例如2.jpg

MemoryStream中已经读到图片数据,如何生成图片文件

[wdgphc]

MemoryStream ms = ...
Image image = Image.FromStream(ms);
image.Save("c:\\2.jpg");

[wangjinbao163]

这样写对吗?为什么image中不显示???
byte[] b = (Byte[])rd["pict"];
System.IO.MemoryStream ms = new System.IO.MemoryStream(b);
ms.Write(b, 0, b.Length);
System.Drawing.Image bm = System.Drawing.Image.FromStream(ms, true);
bm.Save("c:\\dd4.jpg");
Image2.ImageUrl = "c:\\dd4.jpg";

出错是这样的
file:///C:/Inetpub/wwwroot/jxgl/PersonRecord/Uploadfile/temp.jpg
文件路径怎样更正??

[geniusatm4]

FileStream fs = new FileStream("aa.jpg", System.IO.FileMode.Open);

byte[] imgData = new byte[fs.Length];

fs.Read(imgData, 0, (int)fs.Length);

MemoryStream ms = new MemoryStream(imgData);

Image img = Image.FromStream(ms);

img.Save("bb.jpg");

[figroc]

byte[] b = (Byte[])rd["pict"];
System.IO.MemoryStream ms = new System.IO.MemoryStream(b);
ms.Write(b, 0, b.Length);
ms.Position = 0;
System.Drawing.Image bm = System.Drawing.Image.FromStream(ms, true);
bm.Save("c:\\dd4.jpg");
Image2.ImageUrl = "c:\\dd4.jpg";
