Filewatcher design apps6/4/2023 When creating the CompositeFileProvider, pass one or more IFileProvider instances to its constructor. The CompositeFileProvider combines IFileProvider instances, exposing a single interface for working with files from multiple providers. The manifestName represents the name of the embedded resource containing the manifest. ManifestEmbeddedFileProvider(Assembly, String, String, DateTimeOffset)Īccepts an optional root relative path, lastModified date, and manifestName parameters. The lastModified date scopes the last modification date for the IFileInfo instances returned by the IFileProvider. ManifestEmbeddedFileProvider(Assembly, String, DateTimeOffset)Īccepts an optional root relative path parameter and a lastModified date ( DateTimeOffset) parameter. Specify the root to scope calls to GetDirector圜ontents to those resources under the provided path. ManifestEmbeddedFileProvider(Assembly, String)Īccepts an optional root relative path parameter. Name the embedded resource containing the embedded file manifest.New ManifestEmbeddedFileProvider(typeof(Program).Assembly) Startup.cs: var manifestEmbeddedProvider = The FileProviderSample sample app creates an ManifestEmbeddedFileProvider and passes the currently executing assembly to its constructor. Use glob patterns to specify one or more files to embed into the assembly. To generate a manifest of the embedded files:Īdd the NuGet package to your project. The ManifestEmbeddedFileProvider uses a manifest compiled into the assembly to reconstruct the original paths of the embedded files. The ManifestEmbeddedFileProvider is used to access files embedded within assemblies. The FileProviderSample sample app creates the provider in the Startup.ConfigureServices method using IHostEnvironment.ContentRootFileProvider: var physicalProvider = _env.ContentRootFileProvider The File Provider has no access outside of the applicationRoot directory. Glob patterns can't be passed to the GetFileInfo method. The File Provider can be used to iterate through the directory specified by applicationRoot or call GetFileInfo to obtain a file's information. Var fileInfo = provider.GetFileInfo(filePath) Var filePath = Path.Combine("wwwroot", "js", "site.js") Var contents = provider.GetDirector圜ontents(string.Empty) The following code shows how to use PhysicalFileProvider to obtain directory contents and file information: var provider = new PhysicalFileProvider(applicationRoot) Glob patterns aren't supported in the directory path. When instantiating this provider directly, an absolute directory path is required and serves as the base path for all requests made using the provider. The most common scenario for creating and using a PhysicalFileProvider is to request an IFileProvider in a constructor through dependency injection. This scoping prevents access to the file system outside of the specified directory and its children. PhysicalFileProvider uses the System.IO.File type (for the physical provider) and scopes all paths to a directory and its children. The PhysicalFileProvider provides access to the physical file system. Used to access the system's physical files. Used to access files embedded in assemblies. Used to provide combined access to files and directories from one or more other providers. The following table lists implementations of IFileProvider. The FileProviderSample sample app demonstrates how to configure a File Provider in Startup.ConfigureServices for use throughout the app via dependency injection. You can read from the file using the IFileInfo.CreateReadStream method. IFileInfo provides methods and properties for working with files: Set up change notifications (using an IChangeToken).Obtain directory information ( IDirector圜ontents).View or download sample code ( how to download) File Provider interfaces NET Core tooling uses File Providers and glob patterns to specify which files should be published. Razor uses File Providers to locate pages and views.Static File Middleware uses File Providers to locate static files.IWebHostEnvironment exposes the app's content root and web root as IFileProvider types.File Providers are used throughout the ASP.NET Core framework. ASP.NET Core abstracts file system access through the use of File Providers.
