问题描述
我有初学者的问题.
如何将文件流保存到服务器上的文件中?!
How to save a file stream to a file on server?!
我知道了:
var source = Request.QueryString["src"];
WebClient webclient = new WebClient();
using (Stream stream = webclient.OpenRead(source))
{
Bitmap iconbitmap = new Bitmap(System.Drawing.Image.FromStream(stream));
FileStream os = new FileStream("./asdasdasd.ico", FileMode.Create);
var ic = MakeIcon(iconbitmap, 16, false); /// function returns an icon
ic.Save(os);
}
我的问题是,当我在 ASP.NET 开发服务器中运行代码时,它会将asdasdasd.ico"保存到:C:Program FilesMicrosoft Visual Studio 9.0Common7IDEasdasdasd.ico
My problem is than when I run code in ASP.NET Development Server it saves "asdasdasd.ico" into: C:Program FilesMicrosoft Visual Studio 9.0Common7IDEasdasdasd.ico
而且,当我在远程服务器上运行它时出现错误.
And, when I run it on remote server got error.
我想把它保存到:www.my-web-site.com/output/asdasdasd.ico
I want to save it into: www.my-web-site.com/output/asdasdasd.ico
非常感谢.
推荐答案
使用Server.MapPath()
(还有一个用于关闭文件的 using
块会有所帮助):
Use Server.MapPath()
(also a using
block for closing the file would help):
using(FileStream os = new FileStream(Server.MapPath("/output/asdasdasd.ico"), FileMode.Create))
{
var ic = MakeIcon(iconbitmap, 16, false); /// function returns an icon
ic.Save(os);
}
