如何使用 MVC 以最小访问权限在服务器上记录文件。该代码的下一个版本不适合，因为它会堵塞域。

控制器代码：

var fileFile = Request.Files["p" + prop.Id];
if (fileFile == null) continue;

string pathFile = AppDomain.CurrentDomain.BaseDirectory + "UploadedFiles";
string filenameFile = Path.GetFileName(fileFile.FileName);

if (filenameFile != null) fileFile.SaveAs(Path.Combine(pathFile, filenameFile));

（如果可以通过将文件放入缓存来实现这一点）

编辑代码：

varordinaryPropertyValue = new Catalog.Core。 Entities.OrdinaryPropertyValue();

环境.CurrentDirectory = 环境.GetEnvironmentVariable("TEMP");

var fileFile = Request.Files["File" + prop.Id]; if (fileFile == null) 继续;

字符串路径文件=环境.当前目录;

文件文件.另存为(路径文件);

普通PropertyValue.Value = pathFile;

instance.SetPropertyValue(prop.Id,ordinaryPropertyValue);

How to record files on a server with minimal access using MVC. The next version of the code is not suitable as it will be clogging up the domain.

Controller code:

var fileFile = Request.Files["p" + prop.Id];
if (fileFile == null) continue;

string pathFile = AppDomain.CurrentDomain.BaseDirectory + "UploadedFiles";
string filenameFile = Path.GetFileName(fileFile.FileName);

if (filenameFile != null) fileFile.SaveAs(Path.Combine(pathFile, filenameFile));

(if it is possible to realize this by putting file to the cache)

EDITED CODE:

var ordinaryPropertyValue = new Catalog.Core.Entities.OrdinaryPropertyValue();

Environment.CurrentDirectory = Environment.GetEnvironmentVariable("TEMP");

var fileFile = Request.Files["File" + prop.Id];
if (fileFile == null) continue;

string pathFile = Environment.CurrentDirectory;

fileFile.SaveAs(pathFile);

ordinaryPropertyValue.Value = pathFile;

instance.SetPropertyValue(prop.Id, ordinaryPropertyValue);

您可以使用通用的应用程序数据位置（如果您需要保留它们，这将比 %TEMP% 更好 - 根据我的经验，人们倾向于不时清理 %TEMP% 文件夹） - 所有用户都应该有访问该文件夹，然后您可以将其放入子文件夹中，如下所示：

var appDataFolder = System.Environment.GetFolderPath(SpecialFolder.CommonApplicationData);
var dir = Path.Combine(Path.Combine(appDataFolder, "My Application"), "UploadedFiles"):

// save your files into dir

以下是所有“特殊文件夹”，以防您看到您更愿意使用的文件夹：Environment.SpecialFolder

You could use the common application data location (this would be better than %TEMP% if you need them to stick around - people have a tendency to clean the %TEMP% folder out from time to time in my experience) - all users should have access to that and then you could just put it in a sub-folder like so:

var appDataFolder = System.Environment.GetFolderPath(SpecialFolder.CommonApplicationData);
var dir = Path.Combine(Path.Combine(appDataFolder, "My Application"), "UploadedFiles"):

// save your files into dir

Here are all the "special folders" in case you see one that you would rather use: Environment.SpecialFolder
