然后,我们调用ConnectAsync方法并传入CancellationToken。如果连接在超时之前未完成,将抛出TaskCanceledException异常。 总结 以上三种方法都可以用来为TcpClient设置连接超时。选择哪种方法取决于你的具体需求和所使用的.NET版本。如果你使用的是.NET 4.5或更高版本,建议使用第三种方法,因为它提供了更现代和灵活的异步编程模型...
if(!client.ConnectAsync(ip.Trim(),Convert.ToInt32(port.Trim())).Wait(5000)) //设置5秒超时 { recv_text_data = "SocketException Connect Error!"; } if (client.Connected) { NetworkStream serverStream = client.GetStream(); var newmsg = new SerMessage(); var client = new TcpClient(); i...
}//we have connectedclient.EndConnect(result); .Net 4.5的简便写法 varclient =newTcpClient();if(!client.ConnectAsync("remotehost", remotePort).Wait(1000)) {//connection failure} 代码出处: https://stackoverflow.com/questions/17118632/how-to-set-the-timeout-for-a-tcpclient...
EN从.NET 4.5开始，TcpClient有一个很酷的ConnectAsync方法，我们可以像这样使用，所以现在非常简单：...
if (!client.ConnectAsync("remotehost", remotePort).Wait(1000)){ // connection failure } 4.5以前 var client = new TcpClient();var result = client.BeginConnect("remotehost", this.Port, null, null);var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(1));if (!success){ throw...
int retryCount = 0; const int maxRetryCount = 3; while (retryCount < maxRetryCount) { try { TcpClient client = new TcpClient(); await client.ConnectAsync("example.com", 80); // 连接成功,跳出循环 break; } catch (Exception ex) { // 处理异常 retryCount++; if (retryCount >= maxRetr...
ConnectAsync(String, Int32) 将客户端连接到指定主机上的指定 TCP 端口以作为异步操作。 Dispose() 释放由 TcpClient 占用的托管和非托管资源。 Dispose(Boolean) 释放由 TcpClient 占用的非托管资源,还可以另外再释放托管资源。 EndConnect(IAsyncResult) 结束挂起的异步连接尝试。 Equals(Object) 确定指定对象...
