// args[1] can be an IPaddress or host name.

   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;

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

Hinweise

Wenn der Wert des Status ist nicht Success, Sie sollten nicht verwenden, die Rückgabewerte der RoundtripTime, Options oder Buffer Eigenschaften.If the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. Die RoundtripTime und Buffer Eigenschaften gibt 0 (null), und die Options -Eigenschaft zurück null.The RoundtripTime and Buffer properties will return zero, and the Options property will return null.
