File Providers
ASP.NET Core abstracts file system access through the use of File Providers. File Providers are used throughout the ASP.NET Core framework:
IHostingEnvironment exposes the app's content root and web root as
IFileProvider
types.Static File Middleware uses File Providers to locate static files.
Razor uses File Providers to locate pages and views.
File Provider interfaces
The primary interface is IFileProvider
. It exposes methods to:
Obtain file information (
IFileInfo
).Obtain directory information (
IDirectoryContents
).Set up change notifications (using an
IChangeToken
).
IFileInfo
provides methods and properties for working with files:
Exists
IsDirectory
Name
Length (in bytes)
LastModified date

Three implementations of IFileProvider
are available.
