Microsoft.Extensions.FileProviders.Physical

About

Provides an implementation of a physical file provider, facilitating file access and monitoring on the disk. The primary type, PhysicalFileProvider, enables the lookup of files on disk and can watch for changes either via FileSystemWatcher or polling mechanisms.

Key Features

• Easy access and monitoring of files on the disk.
• Ability to watch for file changes either by using FileSystemWatcher or through polling.

How to Use

This library can be used to look up files on disk and monitor file changes effectively. Below is an example of how to use the PhysicalFileProvider to access files on disk and monitor changes:

using Microsoft.Extensions.FileProviders;
using Microsoft.Extensions.FileProviders.Physical;

using var provider = new PhysicalFileProvider(AppContext.BaseDirectory);

Environment.SetEnvironmentVariable("DOTNET_USE_POLLING_FILE_WATCHER", "1");

var contents = provider.GetDirectoryContents(string.Empty);
foreach (PhysicalFileInfo fileInfo in contents)
{
    Console.WriteLine(fileInfo.PhysicalPath);
}

var changeToken = provider.Watch("*.txt");
changeToken.RegisterChangeCallback(_ => Console.WriteLine("Text file changed"), null);

Console.ReadLine();
