我正在为我的关卡项目使用C＃和unity编写消息传递应用程序，它使用的是tcp客户端服务器模型。我创建了一个可以接收消息的套接字列表，但是我必须指定要从中接收消息的套接字，这在我只有1个客户端但可以处理更多连接和循环的情况下可以很好地进行测试通过每个套接字尝试从中接收消息似乎效率很低而且很慢。
我的问题是：如何在不使用上述方法的情况下从多个客户端接收消息？
我将发布特定部分，然后发布整个代码，以便您了解我在做什么。
这是处理从套接字接收数据的线程
public static void Thread1()
{
for (int i = 0; i <= 2; i++)
{
byte[] b = new byte[155];
///////// I need to specify the socket to receive from////////
int k = counter.numbers1[counter.i2].Receive(b);
//////////////////////////////////////////////////////////////
string k1 = "";
for (int i3 = 0; i3 < k; i3++)
k1 = k1 + Convert.ToChar(b[i3]);
Console.WriteLine(k1);
string sender_endpoint = k1.Substring(0, 21); ;
string receiver_endpoint = k1.Substring(22, 21);
string message = k1.Substring(44, 100);
string msgtype = k1.Substring(145, 1);
Console.WriteLine(k1.Length);
Console.WriteLine(sender_endpoint);
Console.WriteLine(receiver_endpoint);
Console.WriteLine(message);
Console.WriteLine(msgtype);
if (msgtype == "0") //message
{
Console.WriteLine("000");
}
else if (msgtype == "1") //command
{
Console.WriteLine("111");
}
}
}

完整的客户端代码为：
public class cc : MonoBehaviour
{
public InputField NameField;
private string x;
private string y = "";
//private int z = 0;
static class ipadressnumber{
public static string ipadressno = "192.168.1.250";
}
public void Start(){
TcpClient tcpclnt = new TcpClient();
tcpclnt.Connect(ipadressnumber.ipadressno,8080);
Stream stm = tcpclnt.GetStream();
byte[] bb=new byte[100];
int k=stm.Read(bb,0,100);
for (int i=0;i<k;i++){
y = y + Convert.ToChar(bb[i]);
}
//Debug.Log(y);
tcpclnt.Close();
}
public void OnSubmit()
{
x = NameField.text;
//Debug.Log(x);
try
{
System.Net.IPAddress ipad = IPAddress.Parse(ipadressnumber.ipadressno);
IPEndPoint ipLocalEndPoint = new IPEndPoint(ipad,8888);
//TcpClient clientSocket = new TcpClient(ipLocalEndPoint);
TcpClient tcpclnt1 = new TcpClient();
//Debug.Log(y);
tcpclnt1.Connect(ipadressnumber.ipadressno,int.Parse(y));
Stream stm = tcpclnt1.GetStream();
byte[] bb=new byte[100];
int k=stm.Read(bb,0,100);
string lclep = "";
for (int i=0;i<k;i++)
{
lclep = lclep + Convert.ToChar(bb[i]);
}
String str=x;
////////////format of message:(sender endpoint, recipient endpoint, message, message type, check sum/digit)
string message = "";
int strlen = 21;
int msglen = 100;
string msgtype = "0";// 0 = message, 1 = command
lclep = Convert.ToString(lclep);
Debug.Log (lclep);
while (strlen > lclep.Length)
{
Debug.Log('1');
lclep = lclep + "#";
}
string rmtep = "000.00.00.000:8000";
while (strlen > rmtep.Length)
{
Debug.Log ('2');
rmtep = rmtep + "#";
}
while (msglen > x.Length)
{
Debug.Log ('3');
x = x + "#";
}
message = message + lclep + ':' + rmtep + ':' + x + ':' + msgtype + ':';
Debug.Log(message);
ASCIIEncoding asen= new ASCIIEncoding();
byte[] ba = new byte[155];

stm.Write(ba,0,ba.Length);
tcpclnt1.Close();
}
catch (Exception e) {
Console.WriteLine("Error..... " + e.StackTrace);

}
}

您可以看到我没有收到任何错误，所以我所需要的只是一种从多个客户端接收消息的方法。
答案 0 :(得分：0)
最好有一个最小，完整和可验证的示例https://stackoverflow.com/help/mcve，但我将为我提出的问题提供一个可能的解决方案：如何侦听多个套接字并同时处理它们的消息。
您可以为所需的每个套接字启动一个线程，该读取器线程将读取整个消息，并发送到另一个我称为处理线程的线程中的线程安全列表。最后一个线程将把您的业务逻辑应用于套接字读取的数据，生成响应并将其发送到另一个线程：Writer Thread。
Socker->读取器->处理器-> Writer
不要像在Thread3和Thread2方法中那样启动线程，这会占用过多的CPU，并且会减慢分配速度。预先创建线程，然后按适当的顺序开始。
