How to connect to ChatGPT API with .NET?

To connect to the ChatGPT API with .NET, you will be required to create an HTTP client to send HTTP requests and handle HTTP responses. You can utilize the `HttpClient` class available in the .NET Foundation.

Here’s an example of how you might achieve this:

```
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

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

static void Main(string[] args) { RunAsync().GetAwaiter().GetResult(); } static async Task RunAsync() { client.DefaultRequestHeaders.Clear(); client.DefaultRequestHeaders.Add(“Authorization”, “Bearer YOUR_OPENAI_API_KEY”); HttpResponseMessage response = await client.PostAsJsonAsync(“https://api.openai.com/v1/engines/davinci-codex/completions”, new { max_tokens = 30, prompt = “Translate the following English text to French: ‘{}’” }); response.EnsureSuccessStatusCode(); string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); } } ```

In this snippet, replace `“Bearer YOUR_OPENAI_API_KEY”` with your API key that OpenAI has provided. The code generates a POST request to the OpenAI API and configures the request to include your authorization token in the headers.

Remember to handle exceptions that may be thrown during the execution of the HTTP request. This example also uses `async/await` – make sure your methods are setup to handle this correctly (especially in the case of a UI application).
