네임스페이스:

System.Net.NetworkInformation

어셈블리:

System.Net.Ping.dll

Source:

PingReply.cs

ICMP(Internet Control Message Protocol) Echo Request를 보내고 이에 대응하는 ICMP Echo Reply 메시지를 받는 데 걸린 시간(밀리초)을 가져옵니다.

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

public long RoundtripTime { get; }

member this.RoundtripTime : int64

Public ReadOnly Property RoundtripTime As Long

속성 값

Int64

라운드트립 시간(밀리초)을 나타내는 Int64입니다.

예제

다음 코드 예제에서는 동기적으로 ICMP 에코 요청을 보내고이 속성에서 반환 하는 버퍼의 크기를 표시 합니다.

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() );
      Console::WriteLine( "RoundTrip time: {0}", reply->RoundtripTime );
      Console::WriteLine( "Time to live: {0}", reply->Options->Ttl );
      Console::WriteLine( "Don't fragment: {0}", reply->Options->DontFragment );
      Console::WriteLine( "Buffer size: {0}", reply->Buffer->Length );
   }
   else
   {
      Console::WriteLine( reply->Status );
   }
}

public static void ComplexPing ()
{
    Ping pingSender = new Ping ();

    // Create a buffer of 32 bytes of data to be transmitted.
    string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
    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 = new 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 ());
        Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
        Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
        Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
        Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
    }
    else
    {
        Console.WriteLine (reply.Status);
    }
}

설명

Echo 요청이 실패 RoundtripTime 하면 시간은 0으로 보고되며 이는 요청이 성공할 때 유효한 값이기도 합니다. 이 속성에서 반환된 Status 값을 무시해야 하는지 여부를 확인하려면 를 검사 합니다.
