使用主线程但不阻塞it.c#的异步方法示例

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

public class Program
{
    public static async Task Main(string[] args)
    {
        await DoAsyncOperation();
        
        // 执行其他任务...
        
        Console.WriteLine("异步操作完成");
    }
    
    private static async Task DoAsyncOperation()
    {
        using (var httpClient = new HttpClient())
        {
            var response = await httpClient.GetAsync("https://www.example.com");
            
            // 处理响应...
        }
    }
}
