안녕하세요. 안드로이드 전화 Wi-Fi 핫스팟을 사용하여 네트워크를 만든 다음 C#을 사용하여이 핫스팟에 연결합니다.C# TCP 클라이언트가 IP 주소에 연결하지 않습니다.
핫스팟의 ipadress는 192.168.43.1입니다.
먼저 노트북 Wi-Fi로 Wi-Fi 핫스팟에 연결합니다.
지금 내가 사용하고 C# 코드는 :
private void connectToServer()
{
try
{
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting.....");
tcpclnt.Connect("192.168.43.1", 8001);
// use the ipaddress as in the server program
Console.WriteLine("Connected");
Console.Write("Enter the string to be transmitted : ");
String str = Console.ReadLine();
Stream stm = tcpclnt.GetStream();
ASCIIEncoding asen = new ASCIIEncoding();
byte[] ba = asen.GetBytes(str);
Console.WriteLine("Transmitting.....");
stm.Write(ba, 0, ba.Length);
byte[] bb = new byte[100];
int k = stm.Read(bb, 0, 100);
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(bb[i]));
tcpclnt.Close();
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.Message);
}
}
하지만 항상이 예외를 얻을 : 대상 컴퓨터 가 적극적으로 거부했기 때문에
오류를 ..... 연결하지 못했습니다 192.168.43.1:8001
안녕하세요, 일부 검색 후 안녕하세요, netstat를 사용하여 내 컴퓨터에서 포트를 찾을 수 없습니다 :

오류 ..... 대상 컴퓨터가 적극적으로 거부했기 때문에 연결할 수 없습니다. 192.168.43.1:8001 – kemdo
상당히 명확합니다. 대상이 연결을 허용하지 않습니다. –
