使用身份验证凭据的简单C# API Get请求？

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

HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", "Your_Access_Token");

string url = "https://api.example.com/endpoint";
HttpResponseMessage response = await client.GetAsync(url);

if (response.IsSuccessStatusCode)
{
    string result = await response.Content.ReadAsStringAsync();
    Console.WriteLine(result);
}
else
{
    Console.WriteLine("请求失败，错误码：" + response.StatusCode);
}
