[英]Get the absolute server path(physical path) of file for FileInfo
我正在使用EPi服务器提供商:
<add virtualPath="~/WorkplaceFiles/" physicalPath="C:\Temp Files\Workplaces"
name="workplaceFiles" type="EPiServer.Web.Hosting.VirtualPathNativeProvider,EPiServer"
showInFileManager="true" virtualName="workplaceUploadDocuments" bypassAccessCheck="true" maxVersions="5" />
这是提供者的定义:
VirtualPathUnifiedProvider provider =
VirtualPathHandler.GetProvider(DocumentConstants.WorkplaceFiles) as VirtualPathUnifiedProvider;
这就是我的问题 - 如果我像这样定义一个字符串:
string path = "2999/Documents/document.txt"
path = String.Concat(provider.VirtualPathRoot, path);
FileInfo file = new FileInfo(path);
FileInfo
将无法找到此文件,因为它使用的是virtualPath而不是physicalPath。
我如何获取physicalPath,以便我能够使用FileInfo
找到该文件?
// When I'm on this line I would like my path string to be "C:\Temp Files\Workplaces\2999\Documents\document.txt"
FileInfo file = new FileInfo(path);
再次阅读问题,正确的方法似乎是VirtualPathUnifiedProvider.TryGetHandledAbsolutePath
有了它,你会做这样的事情:
string path;
provider.TryGetHandledAbsolutePath("2999/Documents/document.txt", out path);
FileInfo file = new FileInfo(path);
这是你可以做的(如果你只知道VPP提供者的名字):
const string path = "Testbilder/startsidan_896x240.jpg";
var provider = VirtualPathHandler.GetProvider("SiteGlobalFiles") as VirtualPathUnifiedProvider;
if (provider != null)
{
var virtualPath = VirtualPathUtilityEx.Combine(provider.VirtualPathRoot, path);
var file = VirtualPathHandler.Instance.GetFile(virtualPath, true) as UnifiedFile;
if (file != null)
{
var fileInfo = new FileInfo(file.LocalPath);
}
}
如果您已经知道文件的完整虚拟路径,则可以直接转到VirtualPathHandler.Instance.GetFile(...)。
您需要的命名空间是EPiServer.Web和EPiServer.Web.Hosting(和System.IO)。
