IronSharp is a .NET client for

Forked from grcodemonkey/iron_sharp

Getting Started

  1. Go to and sign up.
  2. Create new project at
  3. Download the iron.json file from "Credentials" block of project


PM> Install-Package Iron.IronMQ -Pre


1. Reference the library

using IronSharp.Core;
using IronSharp.IronMQ;

2. Setup your credentials

Also you need to pass authorization data to the client. There are several ways to do it:

  • place .iron.json file to home folder eg. C:\Users\admin\.iron.json
  • place .iron.json file near your executable
  • instantiate IronMqRestClient by passing project id and token: IronSharp.IronMQ.Client.New(new IronClientConfig { ProjectId = "XXXXXXX", Token = "YYYYYYY"});

3. Create an IronMQ client object:

var iromMq = IronSharp.IronMQ.Client.New();

You can specify host settings in iron.json or explicitly in code, for example:

var iromMq = IronSharp.IronMQ.Client.New(new IronClientConfig { ProjectId = "XXXXXXX", Token = "YYYYYYY", Host = "localhost", Scheme = "http", Port = 8080});

Keystone Authentication

Via Configuration File

Add keystone section to your iron.json file:

  "project_id": "57a7b7b35e8e331d45000001",
  "keystone": {
    "server": "",
    "tenant": "some-group",
    "username": "name",
    "password": "password"

In Code

KeystoneClientConfig keystone = new KeystoneClientConfig 
   Tenant = "people",
   Server = "",
   Username = "name",
   Password = "password"
var ironMq = IronSharp.IronMQ.Client.New(new IronClientConfig {ProjectId = "XXXXXXX", Keystone = keystone});

The Basics

Get Queues List

var queues = ironMq.Queues();
foreach (var queueInfo in queues)

Get a Queue Object

You can have as many queues as you want, each with their own unique set of messages.

QueueClient queue = ironMq.Queue("my_queue");

Now you can use it.

Post a Message on a Queue

Messages are placed on the queue in a FIFO arrangement. If a queue does not exist, it will be created upon the first posting of a message.

QueueClient queue = ironMq.Queue("my_queue");
string messageId = queue.Post("Hello World!");

Retrieve Queue Information

QueueInfo info = queue.Info();

Get a Message off a Queue

QueueMessage message = queue.Reserve();

Note: you should reserve message if you want to process it.

Delete a Message from a Queue

QueueMessage message = queue.Reserve();

Be sure to delete a message from the queue when you're done with it.


Retrieve Queue Information

QueueInfo info = queue.Info();

QueueInfo consists of the following properties:

public class QueueInfo : IInspectable
    public string Id { get; set; }
    public string Name { get; set; }
    public string ProjectId { get; set; }
    public PushType PushType { get; set; }
    public int? Retries { get; set; }
    public int? RetriesDelay { get; set; }
    public int? Size { get; set; }
    public int? TotalMessages { get; set; }
    public int? Timeout { get; set; }         // NEW!
    public int? ExpireTime { get; set; }      // NEW!

Clear a Message Queue

Delete all messages from a queue without deleting a queue


Delete a Message Queue

Delete a queue and all it's messages



Post Messages to a Queue

Single message:

var id1 = queue.Post("message");
// To control parameters like delay, push_headers, pass `MessageOptions` instance.
var headers = new Dictionary<string, string> {{"my_header1", "value1"}, {"my_header2", "value2"}};
var id2 = queue.Post("message", new MessageOptions {Delay = 20});
var id3 = queue.Post("message", new MessageOptions {PushHeaders = headers});
// or construct your own message
var id4 = queue.Post(new QueueMessage("message", new MessageOptions{Delay = 20}));

Multiple messages:

You can also pass multiple messages in a single call.

queue.Post(new[] {"first", "second", "third"});
queue.Post(new object[] {1, 2, 3});
queue.Post(new MessageCollection(new[] { new QueueMessage("1"), new QueueMessage("2"), new QueueMessage("3") }));

To control parameters like delay, you can pass an instance of MessageOptions as a last parameter

queue.Post(new[] {"first", "second", "third"}, new MessageOptions{Delay = 20});
queue.Post(new object[] {1, 2, 3}, new MessageOptions{Delay = 20});


  • Delay: The item will not be available on the queue until this many seconds have passed. Default is 0 seconds. Maximum is 604,800 seconds (7 days).
  • PushHeaders: If the item is sent to a push queue, these headers will be passed to subscribers.

Get Messages from a Queue

All messages should be reserved to be processed. So, method Get reserves messages.

// All methods below reserve the message:
QueueMessage msg;
msg = q.Reserve();
msg = q.Next();

When you pop/get a message from the queue, it is no longer on the queue but it still exists within the system. You have to explicitly delete the message or else it will go back onto the queue after the timeout. The default timeout is 60 seconds. Minimal timeout is 30 seconds.

You also can get several messages at a time:

// reserve 5 messages
MessageCollection messages;
messages = queue.Reserve(5);
messages = queue.Reserve(5, new TimeSpan(0, 0, 10));
messages = queue.Get(5, new TimeSpan(0, 0, 10));

Note: You may not receive all n messages on every request, the more sparse the queue, the less likely you are to receive all n messages.

Peek Messages from a Queue

Peeking at a queue returns the next messages on the queue, but it does not reserve them.

var message = queue.PeekNext();

// or

var messages = q.Peek(13);

Optional parameters:

  • n: The maximum number of messages to peek. Default is 1. Maximum is 100. Note: You may not receive all n messages on every request, the more sparse the queue, the less likely you are to receive all n messages.

Touch Message

You can prolongate period of message reservation.

message = queue.Reserve();

This method is not applicable for messages which not been reserved.

message = queue.PeekNext();
if (!message.Touch())
    Console.WriteLine("Message couldn't be touched");

Release Message

Message could be returned back to queue before the expiration of reservation.

message = queue.Reserve();

This method is not applicable for messages which not been reserved.

message = queue.PeekNext();
if (!message.Release())
    Console.WriteLine("Message couldn't be released");

You can specify the time in seconds after which message will appear in queue:

message.Release(5); // message will appear in queue after 5 seconds

Delete Message

var message = queue.Reserve();

Delete Messages

Batch deleting of messages can be done via deleting MessageCollection

MessageCollection messages = q.Reserve(3);

Or via specifying ids of messages

var id1 = queue.Reserve();
var id2 = queue.Reserve();
q.Delete(new[]{id1, id2});

Multithread execution recomendations

  • Do not use more than 25 threads inside one process. If you need more threads, use several processes.
  • Do not exceed 50 requests per second from each thread
  • Reuse the Client instead of instantiating it for each request.
  • Don't try more than 15-20 consumer threads per queue concurrently. Instead, use long polling with keep alive connections.


PM> Install-Package Iron.IronWorker


// =========================================================
// Worker
// =========================================================

IronWorkerRestClient workerClient = IronSharp.IronWorker.Client.New();

string taskId = workerClient.Tasks.Create("Test", new {Key = "Value"});

Console.WriteLine("TaskID: {0}", taskId);

TaskInfoCollection taskInfoCollection = workerClient.Tasks.List("Test");

foreach (TaskInfo task in taskInfoCollection.Tasks)

ScheduleOptions options = ScheduleBuilder.Build().

var payload = new
    a = "b",
    c = new[] {1, 2, 3}

ScheduleIdCollection schedule = workerClient.Schedules.Create("Test", payload, options);



Queuing a Task

string taskId = workerClient.Tasks.Create("Test", payload, options);

Where payload could be any object:

var payload = new {environment = "development", names = new String[]{"Bob", "Alice"}};

There are following possible Options:

  • Priority: Setting the priority of your job. Valid values are TaskPriority.Default (0), TaskPriority.Medium (1), and TaskPriority.High (2). The default is 0.
  • Timeout: The maximum runtime of your task in seconds. No task can exceed 3600 seconds (60 minutes). The default is 3600 but can be set to a shorter duration.
  • Delay: The number of seconds to delay before actually queuing the task. Default is 0.

Scheduling Options

You can append to ScheduleBuilder.Build() (i.e. instance of ScheduleOptionsBuilder) the following methods:

  • WithFrequency: The amount of time specified with timespan, between runs. By default, the task will only run once. It will return a 400 error if it is set to less than 60. Original API parameter name is run_every.
  • StopAt: The time tasks will stop being queued. Should be an instance of DateTime. Original API parameter name is end_at.
  • StopAfterNumberOfRuns: The number of times a task will run. Original API parameter name is run_times
  • WithPriority: The priority queue to run the job in. Valid values are TaskPriority.Default (0), TaskPriority.Medium (1), and TaskPriority.High (2). The default is 0. Higher values means tasks spend less time in the queue once they come off the schedule. Original API parameter name is priority
  • StartingOn: The time the scheduled task should first be run. Should be an instance of DateTime. Original API parameter name is start_at.
  • RunFor: The amount of time specified with timespan scheduled task should be run for. The same as StopAt(DateTime.Now + duration)
  • Delay: The amount of time execution should be delayed. The same as StartingOn(DateTime.Now + delay)
  • NeverStop: Disables effects from previously called StopAt and StopAfterNumberOfRuns.


PM> Install-Package Iron.IronCache

// =========================================================
// Cache
// =========================================================

IronCacheRestClient ironCacheClient = IronSharp.IronCache.Client.New();

// Get a Cache object
CacheClient cache = ironCacheClient.Cache("my_cache");

// Put value to cache by key
cache.Put("number_item", 42);

// Get value from cache by key

// Get value from cache by key

// Numbers can be incremented
cache.Increment("number_item", 10);

// Immediately delete an item

cache.Put("complex_item", new {greeting = "Hello", target = "world"});

// Get value from cache by key
