我对客户端和服务器应用程序感兴趣。顺便说一句，我正在做实时项目。我遇到了一系列问题，我无法弄清楚。你能帮我看看这个软件吗？让我在下面解释我的项目；
我的项目由两部分组成。其中一个是客户端，另一个是服务器。路由器上有设备。我正在尝试通过以太网连接此设备。我可以通过其 Ipnumber 和端口号（172.16.204.100、50007）连接到设备，并且可以发送我的数据（命令）。
CLIENT PART
namespace client
{
class Program
{
static Socket sck;
//static byte[] Buffer { get; set; }
static void Main(string[] args)
{
Console.Title = "rrrrrr";
sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint localendpoint = new IPEndPoint(IPAddress.Parse("172.16.204.100"), 50007); //50007 bidirectional interface The event
//channel is unidirectional and connects across port 50008.The event channel reports asynchronous events such as errors, tag arrivals, and digital output triggers.
try
{
sck.Connect(localendpoint);
if (sck.Poll(-1, SelectMode.SelectWrite))
{
Console.WriteLine("this socket is writable");
}
else if (sck.Poll(-1, SelectMode.SelectRead))
{
Console.WriteLine("this socket is readable");
}
else if (sck.Poll(-1, SelectMode.SelectError))
{
Console.WriteLine("this socket has an error");
}
}
catch
{
Console.Write(" unable ");
Main(args);
}
Console.Write(" \r\n ");
// Using the RemoteEndPoint property.
Console.WriteLine("I am connected to " + IPAddress.Parse(((IPEndPoint)sck.RemoteEndPoint).Address.ToString()) + " on port number " + ((IPEndPoint)sck.RemoteEndPoint).Port.ToString());
Console.Write(" \r\n ");
// Using the LocalEndPoint property.
Console.WriteLine("My local IpAddress is :" + IPAddress.Parse(((IPEndPoint)sck.LocalEndPoint).Address.ToString()) + " I am connected on port number " + ((IPEndPoint)sck.LocalEndPoint).Port.ToString());
Console.Write(" \r\n ");
Console.Write("enter text: ");
string text = Console.ReadLine();
byte[] data = Encoding.ASCII.GetBytes(text);
sck.Send(data);
Console.Write(" data sent! \r\n ");
//Console.Write(" press ant key to continue ");
Console.Read();
sck.Close();
}
}
}
然后，我编写了我的计算机的 Ipnumber，用于在 Bind 方法中设置 Device 和我的计算机之间的连接。我开始等待得到回应。在这一点上，我一直没有得到答案。我认为我的端口号应该是错误的，这可能会导致问题。我不知道实际上是什么问题。我只知道我无法得到任何回应。
顺便说一句，我刚刚研究了这个平台快 15 天了。我不专业。我对这项工作真的很麻烦。
你能帮我吗？如果有人可以帮助我，我会很高兴他。
SERVER PART
namespace server
{
class Program
{
static byte[] Buffer { get; set; }
static Socket sck;
static void Main(string[] args)
{
Console.Title = " Server ";
sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
sck.Bind(new IPEndPoint(IPAddress.Parse("172.16.204.104"), 4561));
//sck.Bind(new IPEndPoint(IPAddress.Parse("172.16.204.104"), 0));
while (true)
{
sck.Listen(100);
Socket accepted = sck.Accept();
Buffer = new byte[accepted.SendBufferSize];
int bytesRead = accepted.Receive(Buffer);
byte[] formatted = new byte[bytesRead];
for (int i = 0; i < bytesRead; i++)
{
formatted[i] = Buffer[i];
}
string strData = Encoding.ASCII.GetString(formatted);
Console.Write(strData + "\r\n");
Console.Read();
sck.Close();
accepted.Close();
}
}
}
}
