![]() Type nameĭefines status codes that describe the outcome of an ICMP echo request message.Īllows you to configure or retrieve the settings that control how many times the request packet can be forwarded ( Ttl), and whether it can be fragmented ( DontFragment ).Ĭontains the results of an ICMP echo request. The following types are used with the Ping class and are described in detail below. For a detailed description of ICMP messages, see RFC 792, available at. ping may or may not exist on any given device, and ping may or may not exist in any given version of Android. The Send and SendAsync methods send an Internet Control Message Protocol (ICMP) echo request message to a remote computer and wait for an ICMP echo reply message from that computer. 411 1 10 20 3 Do not run shell commands from a production app. This class provides functionality similar to the Ping.exe command line tool. A successful Ping indicates only that the remote host can be reached on the network the presence of higher level services (such as a Web server) on the remote host is not guaranteed. The presence and configuration of proxies, network address translation (NAT) equipment, or firewalls can prevent Ping from succeeding. Network topology can determine whether Ping can successfully contact a remote host. If ( reply->Status = IPStatus::Success )Ĭonsole::WriteLine( "Address: ", ) Īpplications use the Ping class to detect whether a remote computer is reachable. PingReply ^ reply = pingSender->Send( args, timeout, buffer, options ) String^ data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" Īrray^buffer = Encoding::ASCII->GetBytes( data ) Create a buffer of 32 bytes of data to be transmitted. but change the fragmentation behavior. Use the default Ttl value which is 128, To see our average RTT, we can print the rttavgms from the responselist object. responselist ping8.8.8.8, size40, count10) With this ping, we sent 10 ICMP packets with a payload of 40 bytes to Google. PingOptions ^ options = gcnew PingOptions First, we need to store our results in an object. args can be an IPaddress or host name.Īrray^args = Environment::GetCommandLineArgs() Using namespace System::Net::NetworkInformation The following code example demonstrates using the Ping class synchronously.
