如何正确地从C#的HttpClient getAsync捕获异常，以便错误显示“发生了一个或多个错误”？

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

public class Program
{
    public static async Task Main()
    {
        try
        {
            using (HttpClient client = new HttpClient())
            {
                HttpResponseMessage response = await client.GetAsync("https://example.com");

                // 检查响应是否成功
                response.EnsureSuccessStatusCode();

                // 处理响应数据
                string responseBody = await response.Content.ReadAsStringAsync();
                Console.WriteLine(responseBody);
            }
        }
        catch (HttpRequestException ex)
        {
            // 捕获HttpClient请求异常
            Console.WriteLine("发生了一个或多个错误：" + ex.Message);
        }
    }
}
