How to convert from Ruby to .NET

Understanding the Basics: Ruby vs .NET

Ruby is known for its simplicity and productivity, while .NET is a powerful framework developed by Microsoft, often used for building robust and scalable enterprise applications. To successfully convert Ruby code to .NET, it's crucial to understand the fundamental differences between the two.

Ruby is a dynamic, interpreted language with a flexible syntax. .NET, on the other hand, is a framework that supports multiple languages, including C# and VB.NET, with C# being the most commonly used in .NET development.

Setting Up Your .NET Environment

Before beginning your conversion, ensure you have the necessary tools:

  • Visual Studio: The primary IDE for .NET development.
  • .NET SDK: To install the latest SDK, go to the official .NET website and follow the installation guides.
  • Familiarity with C#: Since .NET primarily uses C#, a basic understanding of this language will be beneficial.

Free Ruby to .NET Code Converter: What to Expect

While there are few automatic code converters available, a direct one-to-one mapping from Ruby to .NET may not be feasible due to differences in syntax and runtime environments. The process is typically manual and involves the following steps:

  1. Translating Ruby constructs to their .NET equivalents.
  2. Adapting to the static typing nature of .NET.
  3. Leveraging .NET libraries to replace Ruby gems.

Ruby Data Types to .NET Data Types

Understanding how to translate data types is a fundamental step in conversion:

  • String: Both Ruby and C# (.NET) use String, but Ruby is untyped.
  • Integer: Maps to int or long in .NET.
  • Array: Maps to Array or List<T> in .NET.
  • Hash: Maps to Dictionary<TKey, TValue> in .NET.

Converting Ruby Constructs to .NET

Variables and Methods


def greet(name)
  "Hello, #{name}!"

.NET (C#):

public string Greet(string name)
    return $"Hello, {name}!";

Classes and Inheritance


class Animal
  def make_sound
    "generic sound"

.NET (C#):

public class Animal
    public virtual string MakeSound()
        return "generic sound";

Exception Handling

Ruby uses begin and rescue while .NET uses try and catch:


  # code that might throw an exception
rescue StandardError => e
  puts e.message

.NET (C#):

    // code that might throw an exception
catch (Exception e)

Leveraging .NET Libraries

One of the main differences when converting Ruby to .NET is replacing Ruby gems with .NET libraries. For example, if you're using a Ruby gem for HTTP requests, you would likely use HttpClient in .NET.

Ruby (using net/http):

require 'net/http'

uri = URI('')
response = Net::HTTP.get(uri)
puts response

.NET (using HttpClient):

using System.Net.Http;

HttpClient client = new HttpClient();
string response = await client.GetStringAsync("");

Converting Ruby Blocks to .NET Delegates and Lambdas

Ruby blocks and Procs are akin to delegates and lambdas in .NET:


def perform_task
  yield if block_given?

perform_task { puts "Task performed" }

.NET (C#):

public void PerformTask(Action task)

PerformTask(() => Console.WriteLine("Task performed"));


Converting Ruby to .NET requires understanding both the syntactical differences and the overarching architectural paradigms of each environment. While automatic tools might offer some help, manual conversion ensures you correctly map Ruby's dynamic features to .NET’s statically-typed, enterprise-ready framework.

By following these guidelines and continually refining your understanding of .NET, you can successfully migrate your Ruby applications to leverage the powerful features and tools .NET offers.
