C#我写了一个服务器客户端通过socket通信的程序，在本机上调试，IP和Port同为58.195.50.219，但是总出错？

求高手帮助，需要奖励的话支付宝支付。
提示：由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。 192.168.1.219:12312
客户端：
namespace Client
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
//try
//{
int port = 12312;
string host = "192.168.1.219";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
c.Connect(ipe);
string sendStr = "hello!This is a socket test";
textBox1.Text = "hello!This is a socket test";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
c.Send(bs, bs.Length, 0);
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = c.Receive(recvBytes, recvBytes.Length, 0);
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine(recvStr);
c.Close();
}
}
}
服务器： public void sever()
{
try
{
int port = 12312;
string host = "58.195.50.219";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
s.Bind(ipe);
s.Listen(0);
Socket temp = s.Accept();
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = temp.Receive(recvBytes, recvBytes.Length, 0);
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine(recvStr);
this.textBox1.Text = recvStr;
string sendStr = "Ok!Sucess!";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
temp.Send(bs, bs.Length, 0);
temp.Shutdown(SocketShutdown.Both);
temp.Close();
s.Shutdown(SocketShutdown.Both);
s.Close();
}
catch (ArgumentNullException es)
{
Console.WriteLine("ArgumentNullException: {0}", es);
}
catch (SocketException es)
{
Console.WriteLine("SocketException: {0}", es);
}
Console.ReadLine();
}
Client的IP也为58.195.50.219，上面写错了。
