IronPython Integration Examples

Demonstrations of embedding Python scripts in C# applications using IronPython, with examples of data exchange and interop.

---

Overview

This repository shows how to integrate Python scripts directly into C# applications using IronPython. Two primary examples illustrate different use cases.

---

Installation

Add IronPython to your C# project via NuGet:

Install-Package IronPython -Version 2.7.10

---

Example 1: Getting a List from Python into C#

File: getting_a_list.cs

This example demonstrates:

• Executing Python code from C# that generates a list of squared numbers
• Retrieving variables from the executed Python script
• Converting Python lists to C# collections

Highlights:

• Python script uses list comprehension to create x_squared
• List is retrieved in C# and converted to a C# List
• Values are printed from C# side

---

Example 2: Calling C# Functions from Python

File: calling_cs_function_example.cs

This example demonstrates:

• Executing Python code from C#
• Using C# functions within Python scripts
• Retrieving variables created in Python

Highlights:

• Python script uses C# function log() (alternative to Python's print)
• Python calls custom C# function custom_add()
• Variables created in Python (x, y) are accessed from C# side

---

Key Features

• Data Exchange — Pass data between Python and C#
• Function Interop — Call C# functions from Python
• Embedded Scripts — Define Python code as strings in C#

---

Usage

Running the Examples

1. Create a new C# console application in Visual Studio
2. Install IronPython via NuGet: Install-Package IronPython -Version 2.7.10
3. Copy one of the example files into your project
4. Build and run

Basic Structure

Each example follows this pattern:

using IronPython.Hosting;
using Microsoft.Scripting.Hosting;

// Create Python engine
var engine = Python.CreateEngine();

// Execute Python code as string
engine.Execute(@"
    # Python code here
");

// Access variables from C#
var result = engine.GetVariable("variable_name");

---

Architecture

• Engine Layer — IronPython runtime that interprets Python code
• Scope Layer — Variable namespace where Python variables live
• Interop Layer — Bridges between C# objects and Python code

---

Dependencies

• IronPython 2.7.10 — Install via NuGet
• .NET Framework — 4.0 or higher
