c# 调用接口，避免接口内部卡死，实现超时退出 3.0

using System;
using System.Threading;public class Program
{public static void Main(){// 创建一个新的线程来调用接口Thread thread = new Thread(CallCInterface);thread.Start();// 等待一段时间，如果超时则中断线程bool timeout = !thread.Join(TimeSpan.FromSeconds(5)); // 设置超时时间为5秒if (timeout){thread.Abort(); // 中断线程Console.WriteLine("C interface call timed out.");}else{Console.WriteLine("C interface call completed successfully.");}Console.ReadKey();}public static void CallCInterface(){int i = 0;while(true){Console.WriteLine(i++);Thread.Sleep(1000);}}
}

虽然使用Thread类和Join方法设置连接超时时间，但是在连接超时时直接中止线程并抛出异常是不安全的，并且未正确处理连接超时的情况。建议使用异步方法和Task来处理连接超时

                 _client = new TcpClient();var connectTask = _client.ConnectAsync(_ip, _port);var timeout = Task.Delay(_connectTimeout);await Task.WhenAny(connectTask, timeout);if (!connectTask.IsCompleted){throw new TimeoutException("连接超时");}

添加一个CancellationToken参数，以便能够在需要时取消异步操作。

                    using (var cts = new CancellationTokenSource()){cts.CancelAfter(_connectTimeout);var connectTask = _client.ConnectAsync(_ip, _port);var timeout = Task.Delay(_connectTimeout, cts.Token);await Task.WhenAny(connectTask, timeout);if (!connectTask.IsCompleted){throw new TimeoutException("连接超时");}}
