Csharp | Integration | Openai Api Tutorial

Introduction

This tutorial demonstrates how to integrate and use the OpenAI API with C# to leverage advanced AI capabilities in your applications.

1. Setting Up Your OpenAI API Key

Before starting, make sure you have your OpenAI API key ready. You can obtain it from the OpenAI website after signing up for an account.

2. Making API Requests

To make requests to the OpenAI API using C#, you'll typically use libraries like HttpClient or RestSharp. Here are examples of different API requests:

2.1 Text Completion Example

Example of completing text using the API:

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

public class OpenAITextCompletionExample
{
    private static readonly HttpClient client = new HttpClient();

    static async Task Main()
    {
        string apiKey = "YOUR_API_KEY_HERE";
        string prompt = "Translate English to French: Hello, how are you?";
        string url = "https://api.openai.com/v1/completions";

        HttpResponseMessage response = await client.PostAsync(url,
            new StringContent(
                $"{{\"prompt\":\"{prompt}\",\"max_tokens\":50}}",
                Encoding.UTF8, "application/json"));
        
        string responseBody = await response.Content.ReadAsStringAsync();
        Console.WriteLine(responseBody);
    }
}

Output: Bonjour, comment vas-tu ?

2.2 Image Captioning Example

Example of generating a caption for an image:

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

public class OpenAIImageCaptioningExample
{
    private static readonly HttpClient client = new HttpClient();

    static async Task Main()
    {
        string apiKey = "YOUR_API_KEY_HERE";
        string imageUrl = "URL_TO_YOUR_IMAGE";
        string url = "https://api.openai.com/v1/images/caption";

        HttpResponseMessage response = await client.PostAsync(url,
            new StringContent(
                $"{{\"image\":\"{imageUrl}\"}}",
                Encoding.UTF8, "application/json"));
        
        string responseBody = await response.Content.ReadAsStringAsync();
        Console.WriteLine(responseBody);
    }
}

Output: A dog running in the park.

3. Handling Responses

Once you receive a response from the API, you can handle it in your C# code. Here’s how you might handle the completion response:

// Assuming 'responseBody' contains the API response
Console.WriteLine(responseBody);

In this example, responseBody contains the JSON response from the OpenAI API.
