使用c#调用chatgpt 。以下代码由ai自动生成。

using System;
using System.IO;
using System.Net;
using System.Text;

class Program
{
static void Main()
{
// API的URL
string apiUrl = "https://api.openai.com/v1/chat/completions";

    // 设置API的请求头
    WebRequest request = WebRequest.Create(apiUrl);
    request.Method = "POST";
    request.Headers.Add("Authorization", "Bearer {YOUR_API_KEY}");  // 替换为你的API密钥
    request.ContentType = "application/json";
    
    // 设置API的请求体，包含输入和参数
    string input = "请问天气怎么样？";
    string prompt = "用户：" + input + "\n助理：";
    int maxTokens = 50;
    string requestBody = "{ \"messages\": [{ \"role\": \"system\", \"content\": \"You are a helpful assistant.\" }, { \"role\": \"user\", \"content\": \"" + prompt + "\" }], \"max_tokens\": " + maxTokens + " }";
    byte[] byteArray = Encoding.UTF8.GetBytes(requestBody);
    request.ContentLength = byteArray.Length;
    
    // 发送请求并获取响应
    using (Stream dataStream = request.GetRequestStream())
    {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    WebResponse response = request.GetResponse();
    using (Stream responseStream = response.GetResponseStream())
    {
        StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
        string responseJson = reader.ReadToEnd();
        Console.WriteLine(responseJson);
        // 在这里处理API的响应
    }
    response.Close();
}
