DevelopmentHelpers.Storage.Core 4.0.11

DevelopmentHelpers.Storage.Core

This library allows easier access to Azure Storage as well as Local directory sturcture. With few command you can upload or download entire sturucture to local or Azure storage.

Code Example

Following example shows how to use Azure Storage Classes

1. Create IStorage -- IStorage interface has two implementation local & Azure: use any dependency injection container IStorage storage = new AzureStorage(config,logger); or IStorage storage = new FileSystemStorage(config,logger);

2. Use methods available on the interface: e.g: UploadDirectoryAsync(DirectoryInfo directory, string container);

3. To Add in the Web Application

   1. Create Appsettings
      "DevelopmentHelpers": { "AzureConfiguration": { "AccountName": "account name", "AccountKey": "account key", "UseHttps": "True" } }
   2. Add in the Startup file //Add Azure Storage and make sure required values exists in app settings services.AddAzureStorage(Configuration);
   3. To Use it private readonly IStorage _storage; public IndexModel(IStorage storage) { _storage = storage; }

Motivation

I needed a consistent and easy to use library in .net Standard which I can use it with any project, and be able to download and upload complete directories.
