Implements

IFileProvider IDisposable

Remarks

When the environment variable "DOTNET_USE_POLLING_FILE_WATCHER" is set to "1" or "true", calls to Watch(String) will use PollingFileChangeToken.

Constructors

PhysicalFileProvider(String)	Initializes a new instance of a PhysicalFileProvider at the given root directory.
PhysicalFileProvider(String, ExclusionFilters)	Initializes a new instance of a PhysicalFileProvider at the given root directory.

Properties

Root	The root directory for this instance.
UseActivePolling	Gets or sets a value that determines if this instance of PhysicalFileProvider actively polls for file changes. When true, the IChangeToken returned by Watch(String) actively polls for file changes (ActiveChangeCallbacks is true) instead of being passive. This property is only effective when UsePollingFileWatcher is set.
UsePollingFileWatcher	Gets or sets a value that determines if this instance of PhysicalFileProvider uses polling to determine file changes. By default, PhysicalFileProvider uses FileSystemWatcher to listen to file change events for Watch(String). FileSystemWatcher is ineffective in some scenarios such as mounted drives. Polling is required to effectively watch for file changes.

Methods

Dispose()	Disposes the provider. Change tokens may not trigger after the provider is disposed.
Dispose(Boolean)	Disposes the provider.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetDirectoryContents(String)	Enumerate a directory at the given path, if any.
GetFileInfo(String)	Locate a file at the given path by directly mapping path segments to physical directories.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
Watch(String)	Creates an IChangeToken for the specified filter. Globbing patterns are interpreted by Matcher.
