在Windows CE中使用C＃代码进行Internet检测 [英] Internet Detection using code by C# in windows CE

问题描述

嗨
我需要了解我的拨号连接是连接还是未连接。

我使用过这个dll和代码，但有时它不能正确回答：

任何其他解决方案将不胜感激，tnx

 [DllImport（  wininet.dll）] 
  private  < span class =code-keyword> extern   static   bool  InternetGetConnectedState（ out   int 描述， int  ReservedValue）; 
 
  public   static   bool  IsConnected（）
 {
  try  
 {
  int  ConnDesc; 
  return  InternetGetConnectedState（ out  ConnDesc， 0 < /跨度>）; 
} 
  catch  
 {
  return  假; 
} 
} 
 

解决方案

尝试Ping到远程网络服务器，即google.com和收集回复...



http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping.aspx [ ^ ]

 使用 OpenNETCF.Net.NetworkInformation; 
 
  bool  result =  false ; 
 
 Ping ping =  new  Ping（）; 
 
 PingReply pingReply = ping.Send（  www.google.com ）; 
 
  if （pingReply.Status == IPStatus.Success）
 result =  true ; 

Hi I need to understand whether my dial-up connection is connected or is not connected.
I have used this dll and code, but sometimes it doesn't give me correct answer:
any other solutions will be appreciated, tnx

[DllImport("wininet.dll")]
       private extern static bool InternetGetConnectedState(out int Description, int ReservedValue);

public static bool IsConnected()
       {
           try
           {
               int ConnDesc;
               return InternetGetConnectedState(out ConnDesc, 0);
           }
           catch
           {
               return false;
           }
       }

解决方案

Try Pinging to a remote webserver ie, google.com and collect the reply...

http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping.aspx[^]

using OpenNETCF.Net.NetworkInformation;

            bool result = false;

            Ping ping = new Ping();

            PingReply pingReply = ping.Send("www.google.com");

            if (pingReply.Status == IPStatus.Success)
                result = true;
