没有链接到服务器！System.Net.Sockets.socketException;由于目标及积极拒绝，无法连接。127.0.0.1：655010

服务端的部分代码：

private void Listen() {

TcpListener tcpListener = new TcpListener(65501);

tcpListener.Start();

Socket socketForClient = tcpListener.AcceptSocket();

try {

NetworkStream networkStream = new NetworkStream(socketForClient);

StreamReader streamReader = new StreamReader(networkStream);

string msg = streamReader.ReadLine();

listBoxServer.Items.Add("已经建立客户端成功连接！");

while (true) {

networkStream = new NetworkStream(socketForClient);

streamReader = new StreamReader(networkStream);

string message = streamReader.ReadLine();

listBoxServer.Items.Add("收到客户端信息：" + message);

StreamWriter streamWrite = new StreamWriter(networkStream);

if (txtBoxServer.Text != "") {

listBoxServer.Items.Add("客户端反馈信息：" + txtBoxServer.Text);

streamWrite.WriteLine(txtBoxServer.Text);

streamWrite.Flush(); } } }

catch (Exception es) {

MessageBox.Show(es.ToString()); } }

private void bnConnect_Click(object sender, EventArgs e) {

listBoxServer.Items.Add("服务已经启动！");

Thread thread = new Thread(new ThreadStart(Listen));

thread.Start(); }

private void bnClose_Click(object sender, EventArgs e) {

//关闭相关线程及服务。}

客户端的部分代码：

public FormClient() {

InitializeComponent();

try {

tcpClient = new TcpClient("127.0.0.1", 65501); }

catch (Exception es) {

MessageBox.Show("没有链接到服务器！"+es.ToString());

return; }

networkStream = tcpClient.GetStream();

streamReader = new StreamReader(networkStream);

streamWriter = new StreamWriter(networkStream); }

private void bnSend_Click(object sender, EventArgs e){

if (txtBoxClient.Text == "") {

MessageBox.Show("请确定文本框为非空！");

txtBoxClient.Focus();

return; }

try {

string msg;

streamWriter.WriteLine(txtBoxClient.Text);

streamWriter.Flush();

msg = streamReader.ReadLine();

listBoxClint.Items.Add("读取服务器端发送内容：" + msg); }

catch (Exception es) {

MessageBox.Show("从服务器端读取数据出显错误，类型为：" + es.ToString()); } }

private void FormClient_FormClosed(object sender, FormClosedEventArgs e){

//关闭相关线程及服务。 }

运行后出现了服务器积极拒绝的问题，网络大侠请赐教，看看我那出错了！
