TcpClient 连接延迟

Question

我迷路了。当我想在我的 Form1 中编辑某些内容时，我必须在编辑后执行命令 Form1.show();所以我不编辑打开的表格，而是编辑一些看不见的新表格。我认为它在构造函数中的某个地方，但我不知道在哪里。请帮助

Cli class:

    public class Cli
{
    Form1 frm;
    TcpClient tcpclnt = new TcpClient();

    public Cli()
    {


    }
    public void Connect()
    {
        frm = new Form1();
        try
        {

            frm.debug.Text = "Connecting";

            tcpclnt.Connect("127.0.0.1", 8001);
            // use the ipaddress as in the server program
            frm.debug.Text = "Connected";

        }
        catch (Exception e)
        {
            frm.debug.Text=("Error..... " + e.StackTrace);
            frm.Show();
        }...

表格 1 class:

    public partial class Form1 : Form
{
    Cli client;
    public int pocet = 0;
    public Form1()
    {
        InitializeComponent();
        client  =new Cli();
        Random rnd = new Random();

        pocet = rnd.Next(23, 10000);
        if (pocet % 2 == 1)
        {
            label1.Text = "HRAJEŠ";
        }
        else { label2.Text = "HRAJEŠ"; }



    }...

没有无限循环，我认为你遇到了延迟，因为它要等到 TcpClient.Connect() returns。

改为尝试异步连接。

frm.debug.Text = "Connecting";

var client = new TcpClient();
var result = client.BeginConnect("127.0.0.1", 8001, null, null);

var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(1));

if (!success)
{
    throw new Exception("Failed to connect.");
}

// we have connected

frm.debug.Text = "Connected";
client.EndConnect(result);
