LiteX.Storage.Local 3.0.0

This client library enables working with the Local File System Blob service for storing binary data. Wrapper around the Local File System Blob to handle container instantiations for any type of application (ASP.NET Core, .Net Standard 2.x). A very simple .NET interface to blob storage and basic wrapper around the Local File System Storage API.

There is a newer version of this package available.

LiteXStorage

Abstract interface to implement any kind of basic blob storage services (e.g. Azure, Amazon, Google, Local FileSystem) for any type of application (ASP.NET Core, .Net Standard 2.x).

Add a dependency

Nuget

Run the nuget command for installing the client as,

  • Install-Package LiteX.Storage.Core
  • Install-Package LiteX.Storage.Local

Configuration

AppSettings

{
  //LiteX Local File System Storage settings
  "FileSystemBlobConfig": {
    "Directory": "--- REPLACE WITH YOUR LOCAL FILE SYSTEM DIRECTORY ---"
  }
}

Startup Configuration

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // 1. Use default configuration from appsettings.json's 'FileSystemBlobConfig'
        services.AddLiteXFileSystemBlobService();

        //OR
        // 2. Load configuration settings using options.
        services.AddLiteXFileSystemBlobService(option =>
        {
            //option. = "";
        });

        //OR
        // 3. Load configuration settings on your own.
        // (e.g. appsettings, database, hardcoded)
        var fileSystemBlobConfig = new FileSystemBlobConfig();
        services.AddLiteXFileSystemBlobService(fileSystemBlobConfig);
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
