如果我运行Server App。发生异常:在Dinle.Start()

System.Net.SocketException - 通常只允许使用每个套接字地址(协议/网络地址/端口)

我该如何解决这个错误?

        {
            InitializeComponent();

            try
            {
                kanal = new Thread(new ThreadStart(Dinle));
                kanal.Start();
                kanal.Priority = ThreadPriority.Normal;

            {
                this.Text = "kanal çalışmadı";
                MessageBox.Show("hata:" + ex.ToString());
                kanal.Abort();
                throw;

        }

        private void Server_Load(object sender, EventArgs e)

            Dinle();

        void Dinle()
        {
          //  IPAddress localAddr = IPAddress.Parse("localhost");
            // TcpListener server = new TcpListener(port);

                {
                   

Dinle.Start();

Exception is occured. Socket Baglanti = Dinle.AcceptSocket(); if (!Baglanti.Connected) { MessageBox.Show("Baglanti Yok"); } else { TcpClient tcpClient = Dinle.AcceptTcpClient(); if (tcpClient.ReceiveBufferSize > 0) { byte[] Dizi = new byte[250000]; Baglanti.Receive(Dizi, Dizi.Length, 0); string Yol; saveFileDialog1.Title = "Dosyayi kaydet"; saveFileDialog1.ShowDialog(); Yol = saveFileDialog1.FileName; FileStream Dosya = new FileStream(Yol, FileMode.Create); Dosya.Write(Dizi, 0, Dizi.Length - 20); Dosya.Close(); listBox1.Items.Add("dosya indirildi"); listBox1.Items.Add("Dosya Boyutu=" + Dizi.Length.ToString()); listBox1.Items.Add("İndirilme Tarihi=" + DateTime.Now); listBox1.Items.Add("--------------------------------"); } } } } catch (Exception ex) { MessageBox.Show("hata:" + ex.ToString()); } } } }

多次调用TcpListener.Start。

1-在服务器构造函数中启动线程时调用 2-通过Server_Load事件处理程序中的Dinle调用 3-再次单击btn_Listen_Click事件处理程序中的按钮

我并不认为你已经完全掌握了你想要做的事情,但我认为这可以简化。

首先,您应该创建并启动一次侦听器,让我们说代码何时开始运行。之后,您可以进入一个调用AcceptTcpClient以接受连接并处理通信的循环。

您似乎也在混合Socket和TcpClient,这是不需要的。请查看以下内容,例如使用TcpListener和TcpClient的基本示例。
