PingReply.RoundtripTime Свойство

public:
 property long RoundtripTime { long get(); };

public long RoundtripTime { get; }

member this.RoundtripTime : int64

Public ReadOnly Property RoundtripTime As Long

Значение Int64, указывающее время кругового пути в миллисекундах.

Следующий пример кода синхронно отправляет эхо-запрос ICMP и отображает размер буфера, возвращаемого этим свойством.

void ComplexPing()

   Ping ^ pingSender = gcnew Ping;
   
   // Create a buffer of 32 bytes of data to be transmitted.
   String^ data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
   array<Byte>^buffer = Encoding::ASCII->GetBytes( data );
   
   // Wait 10 seconds for a reply.
   int timeout = 10000;
   
   // Set options for transmission:
   // The data can go through 64 gateways or routers
   // before it is destroyed, and the data packet
   // cannot be fragmented.
   PingOptions ^ options = gcnew PingOptions( 64,true );
   
   // Send the request.
   PingReply ^ reply = pingSender->Send( "www.contoso.com", timeout, buffer, options );
   if ( reply->Status == IPStatus::Success )
   {
      Console::WriteLine( "Address: {0}", reply->Address->ToString() );

Если запрос Echo завершается сбоем RoundtripTime , время указывается как 0, что также является допустимым значением при успешном выполнении запроса. Необходимо проверка , Status чтобы определить, следует ли игнорировать значение, возвращаемое этим свойством.
