Beispiele

Im folgenden Codebeispiel wird die Ping Verwendung der-Klasse zum synchronen Senden einer ICMP-Echo Anforderung und zum Anzeigen der Antwort veranschaulicht.The following code example demonstrates using Ping class to send an ICMP echo request synchronously and display the response.

#using <System.dll>

using namespace System;
using namespace System::Net;
using namespace System::Net::NetworkInformation;
using namespace System::Text;

// args[1] can be an IPaddress or host name.
int main()

   array<String^>^args = Environment::GetCommandLineArgs();
   
   Ping ^ pingSender = gcnew Ping;
   PingOptions ^ options = gcnew PingOptions;
   
   // Use the default Ttl value which is 128,
   // but change the fragmentation behavior.
   options->DontFragment = true;
   
   // Create a buffer of 32 bytes of data to be transmitted.
   String^ data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
   array<Byte>^buffer = Encoding::ASCII->GetBytes( data );
   int timeout = 120;
   PingReply ^ reply = pingSender->Send( args[ 1 ], timeout, buffer, options );
   
   if ( reply->Status == IPStatus::Success )

      Console::WriteLine( "Don't fragment: {0}", reply->Options->DontFragment );
      Console::WriteLine( "Buffer size: {0}", reply->Buffer->Length );
   }

Hinweise

Wenn der Wert von Status nicht Successist, sollten Sie nicht die Werte verwenden, die von RoundtripTimeden Options Eigenschaften Buffer , oder zurückgegeben werden.If the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. Die RoundtripTime - Buffer Eigenschaft und die-Eigenschaft geben NULL Options zurück, und nulldie-Eigenschaft gibt zurück.The RoundtripTime and Buffer properties will return zero, and the Options property will return null.
