소켓 예외

Question

나는 웹 클라이언트에서 일하고있다.

using System; 
using System.Threading; 
using Microsoft.SPOT; 
using Microsoft.SPOT.Hardware; 
using GHIElectronics.NETMF.FEZ; 
using EPI.Net; 

namespace FEZ_Cobra_Console_Application1 
{ 
    public class Program 
    { 
     public static string endPoint = "http://192.*********/webservice.asmx"; 
     public static int i = 1; 
     public static void Main() 
     { 
      while (true) 
      { 
       EfficientPutRequest Servicio = new EfficientPutRequest(endPoint); 
       Servicio.SendRequest(System.DateTime.Now, 17, 17, 0, ""); 
       Debug.Print(i.ToString() + " sent"); 
       i++; 
       Thread.Sleep(1000); 
      } 
     } 

    } 
} 

그것은 15 메시지를 보낸 후 소켓 오류가 있습니다 : 나는 클라이언트를 테스트하기 위해이 코드를 사용하고

: 여기에 코드입니다. 여기에 오류가 있습니다 :

나는 송신 후에도 소켓을 닫으려고했지만 어느 것도 작동하지 않습니다. 어떤 생각?

편집 : 메시지를 보낸 후 코드를 업데이트하고 소켓을 닫았습니다. 에뮬레이터에서는 정상적으로 작동하지만 내 장치에서는 작동하지 않습니다.

Answer 1

그렇게 해결 :

connection.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.Linger, new byte[] { 0, 0, 0, 0 }); 

그리고이 추가 메시지를 보낸 후 : 업데이트

Answer 2

사용자의 맞춤법이 잘못되었습니다. static string _event = "CrearteEvent"; 그러면 메시지가 작동하지 않게되고 생성자에서 다른 연결을 열기 전에 연결을 닫는 close()를 추가해야합니다.
