Saving an uploaded file with HttpPostedFileBase.SaveAs in a physical path
提问by Lamloumi2
I'd like to save an uploaded file to a physical path by the method HttpPostedFileBase.SaveAs().
我想通过方法将上传的文件保存到物理路径HttpPostedFileBase.SaveAs()。
When I choose a physical path, an exception appears indicates that the path must be virtual.
当我选择物理路径时，出现异常表示路径必须是虚拟的。
var fileName = Path.GetFileName(fileurl.FileName);
var path = "C:/Projets" + fileName;
fileurl.SaveAs(Server.MapPath(path));
How can I change my code to be able to save the file every where I want?
如何更改我的代码以便能够将文件保存在我想要的任何位置？

The Server.MapPathworks only with physical locations that are part of the website. If you want to save the file outside you could use the following:
该Server.MapPath只与网站的部分物理位置工作。如果要将文件保存在外部，可以使用以下命令：
var fileName = Path.GetFileName(fileurl.FileName);
fileurl.SaveAs(Path.Combine(@"c:\projects", fileName));
Make sure though that the account under which your application pool is executing is granted write permissions to this folder.
请确保您的应用程序池所使用的帐户被授予对此文件夹的写入权限。

Server.MapPath is for virtual path. You can try to use Path.GetFullPath(path).
Server.MapPath 用于虚拟路径。您可以尝试使用 Path.GetFullPath(path)。
