B2.NET

B2.NET is a C# client for the Backblaze B2 Cloud Storage service.

B2.NET is still in Beta, so use it in production at your own risk.

Features

Full implementation of the B2 REST API
Experimental support for file FriendlyURL's
UFT-8 and Url Encoding support
Full Async support
Full test coverage
Targets .NET 4.5 and .NET Standard 1.5

nuget

Install-Package B2Net

Install

Stick the B2Net.dll in your project.

Usage

// the B2Client will default to the bucketId provided here
// for all subsequent calls if you set PersistBucket to true.
var options = new B2Options() {
	AccountId = "YOUR ACCOUNT ID",
	ApplicationKey = "YOUR APPLICATION KEY",
	BucketId = "OPTIONAL BUCKET ID",
	PersistBucket = true/false
};
var client = new B2Client(Options);

Authorize

There are two ways to Authorize a B2Client. The old way is slightly more verbose and there is no clear benefit to using it over the static method. The options object returned from the Authorize method will contain the authorizationToken necessary for subsequent calls to the B2 API. This will automatically be handled by the library when necessary. You do not have to keep this object around. The options object requires AccountID and ApplicationKey to authorize.

// New, cleaner way to Authorize using the static `Authorize` method.
var client = new B2Client(B2Client.Authorize(options));
// OR
var client = new B2Client(B2Client.Authorize("ACCOUNTID", "APPLICATIONKEY"));
// OR
var client = new B2Client("ACCOUNTID", "APPLICATIONKEY", "REQUESTTIMEOUT");

The old way:

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var options = await client.Authorize();

Buckets

List Buckets

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucketList = await client.Buckets.GetList();
// [
//   { BucketId: "",
//     BucketName: "",
//     BucketType: "",
//     BucketInfo: Dictionary<string,string> }
// ]

Create a Bucket

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucket = await client.Buckets.Create("BUCKETNAME", "OPTIONAL_BUCKET_TYPE");
// { BucketId: "",
//   BucketName: "",
//   BucketType: "" }

Create a Bucket with options

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucket = await client.Buckets.Create("BUCKETNAME", new B2BucketOptions() {
	CacheControl = 300,
	LifecycleRules = new System.Collections.Generic.List<B2BucketLifecycleRule>() {
		new B2BucketLifecycleRule() {
			DaysFromHidingToDeleting = 30,
			DaysFromUploadingToHiding = null,
			FileNamePrefix = ""
		}
	}
});
// { BucketId: "",
//   BucketName: "",
//   BucketType: "",
//   BucketInfo: Dictionary<string,string>,
//   LifecycleRules: List<B2BucketLifecycleRule> }

Update a Bucket

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucket = await client.Buckets.Update("BUCKETID", "BUCKETYPE");
// { BucketId: "",
//   BucketName: "",
//   BucketType: "" }

Update a Bucket with options

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucket = await client.Buckets.Update("BUCKETID", new B2BucketOptions() {
	CacheControl = 300,
	LifecycleRules = new System.Collections.Generic.List<B2BucketLifecycleRule>() {
		new B2BucketLifecycleRule() {
			DaysFromHidingToDeleting = 30,
			DaysFromUploadingToHiding = null,
			FileNamePrefix = ""
		}
	}
});
// { BucketId: "",
//   BucketName: "",
//   BucketType: "",
//   BucketInfo: Dictionary<string,string>,
//   LifecycleRules: List<B2BucketLifecycleRule> }

Bucket Types

allPrivate
allPublic

Delete a Bucket

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var bucket = await client.Buckets.Delete("BUCKETID");
// { BucketId: "",
//   BucketName: "",
//   BucketType: "" }

Files

Get a list of files

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var fileList = await client.Files.GetList("BUCKETID", "FILENAME");
// Using optional prefix and delimiter
var fileList = await client.Files.GetList("BUCKETID", "FILENAME", prefix: "PREFIX", delimiter: "DELIMITER");
// {
//   NextFileName: "",
//   [
//     { FileId: "",
//       FileName: "",
//       ContentLength: "", 
//       ContentSHA1: "", 
//       ContentType: "" }
//   ]
// }

Upload a file

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var uploadUrl = await client.Files.GetUploadUrl("BUCKETID");
var file = await client.Files.Upload("FILEDATABYTES", "FILENAME", uploadUrl, "AUTORETRY", "BUCKETID", "FILEINFOATTRS");
// { FileId: "",
//   FileName: "",
//   ContentLength: "", 
//   ContentSHA1: "", 
//   ContentType: "",
//   FileInfo: Dictionary<string,string> }

Download a file by id

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var file = await client.Files.DownloadById("FILEID");
// { FileId: "",
//   FileName: "",
//   ContentLength: "", 
//   ContentSHA1: "", 
//   ContentType: "",
//   FileData: byte[],
//   FileInfo: Dictionary<string,string> }

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var file = await client.Files.DownloadName("FILENAME", "BUCKETNAME");
// { FileId: "",
//   FileName: "",
//   ContentLength: "", 
//   ContentSHA1: "", 
//   ContentType: "",
//   FileData: byte[],
//   FileInfo: Dictionary<string,string> }

Get versions for a file

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var file = await client.Files.GetVersions("FILENAME", "FILEID");
// {
//   NextFileName: "",
//   NextFileId: "",
//   [
//     { FileId: "",
//       FileName: "",
//       Action: "", 
//       Size: "", 
//       UploadTimestamp: "" }
//   ]
// }

Delete a file version

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var file = await client.Files.Delete("FILEID", "FILENAME");
// { FileId: "",
//   FileName: ""}

Hide a file version

var client = new B2Client("ACCOUNTID", "APPLICATIONKEY");
var file = await client.Files.Hide("FILEID", "BUCKETID");
// { FileId: "",
//   FileName: "",
//   Action: "",
//   Size: "",
//   UploadTimestamp: ""}

Get info for a file

var client = new B2Client(options);
await client.Authorize();
var file = client.Files.GetInfo("FILEID").Result;
// { FileId: "",
//   FileName: "",
//   ContentSHA1: "",
//   BucketId: "",
//   ContentLength: "",
//   ContentType: "",
//   FileInfo: Dictionary<string,string> }

Large File API

See the Large File tests for usage details.

Errors

Certain errors returned by B2 point to a temporary error with the upload or download of a file. If one of these errors are encountered during an upload or download then the B2Exception that is returned will have the ShouldRetryRequest flag marked true. This is an indication that you should retry the request if you are so inclined.
