当来自URL的XML被中断时C#挂起代码

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

public class Program
{
    public static async Task Main()
    {
        await ProcessXmlAsync();
        Console.WriteLine("XML处理完成");
    }

    public static async Task ProcessXmlAsync()
    {
        try
        {
            HttpClient client = new HttpClient();
            string xmlUrl = "http://example.com/xml";
            HttpResponseMessage response = await client.GetAsync(xmlUrl);
            response.EnsureSuccessStatusCode();
            string xmlContent = await response.Content.ReadAsStringAsync();

            // 在这里对XML进行处理
            // ...

            Console.WriteLine("XML处理成功");
        }
        catch (Exception ex)
        {
            Console.WriteLine("XML处理失败：" + ex.Message);
        }
    }
