所以最近我问了一个关于我在我的服务器 - 客户端程序中遇到的问题的问题，我可以解决问题，即使我在问题上得到的答案根本没有帮助（感谢无论如何：]），但现在我有另一个问题，我需要程序使它成为一个多客户端服务器类型的东西，我真的不知道该怎么做。我对ParameterizedThreadStart有疑问，我是如何把它用于工作等，我已经搜索过它，我知道它是一个线程方法，但仍然不知道我是如何使用它，任何想法？提前谢谢。
客户代码：
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) //connect to server
{
client = new TcpClient();
IPEndPoint IP_End = new IPEndPoint(IPAddress.Parse("192.168.254.34"), 123); // sincronizacao do IP com a porta
try
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
client.Connect(IP_End);
if (client.Connected)
{
STW = new StreamWriter(client.GetStream());
STR = new StreamReader(client.GetStream());
STW.AutoFlush = true;
backgroundWorker1.RunWorkerAsync(); // Começar a receber dados em background
backgroundWorker1.WorkerSupportsCancellation = true; // possibilidade de cancelar o fio
}
else
{
reconnect();
}
}
catch (SocketException exception)
{
MessageBox.Show(exception.Message.ToString());
reconnect();
}
}
public void reconnect()
{
try
{
IPEndPoint IP_End = new IPEndPoint(IPAddress.Parse("192.168.254.34"), 123); // sincronizacao do IP com a porta
client.Connect(IP_End);
STW = new StreamWriter(client.GetStream());
STR = new StreamReader(client.GetStream());
STW.AutoFlush = true;
backgroundWorker1.RunWorkerAsync();
backgroundWorker1.WorkerSupportsCancellation = true;
}
catch (SocketException exception)
{
MessageBox.Show(exception.Message.ToString());
reconnect();
}
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
while(client.Connected)
{
try
{
receive = STR.ReadLine();
this.textBox2.Invoke(new MethodInvoker(delegate () { textBox2.Text=(receive + "\n\r"); }));
receive = "";
}
catch(Exception x)
{
MessageBox.Show(x.Message.ToString());
}
}
}
}
服务器代码：
public partial class Form1 : Form
{
private TcpClient client;
public StreamReader STR;
public StreamWriter STW;
public string receive;
public String text_to_send;
public Form1()
{
InitializeComponent();
}
private void backgroundWorker2_DoWork(object sender, DoWorkEventArgs e)
{
if(client.Connected) //enquanto o cliente tiver conectado pode escrever para o servidor
{
STW.WriteLine(text_to_send);
this.textBox2.Invoke(new MethodInvoker(delegate () { textBox2.Text= (text_to_send + "\n\r"); }));
}
else
{
MessageBox.Show("Envio Falhado!");
}
}
private void button1_Click(object sender, EventArgs e)
{
if (text_to_send != "" && textBox1.Text != "")
{
text_to_send = textBox1.Text;
backgroundWorker2.RunWorkerAsync();
}
else {
MessageBox.Show("Escreva uma mensagem para ser enviada");
}
textBox1.Text = "";
}
private void Form1_Load(object sender, EventArgs e)
{
TcpListener Listener = new TcpListener(IPAddress.Any, 123);
Listener.Start();
client = Listener.AcceptTcpClient();
if (text_to_send != "")
{
text_to_send = "Conexão efetuada com sucesso...";
backgroundWorker2.RunWorkerAsync();
}
STR = new StreamReader(client.GetStream());
STW = new StreamWriter(client.GetStream());
STW.AutoFlush = true;
}
}
服务器代码（正在处理）：
public Form1()

InitializeComponent();
