PingReply::Status Property
Gets the status of an attempt to send an Internet Control Message Protocol (ICMP) echo request and receive the corresponding ICMP echo reply message.
Assembly: System (in System.dll)
If the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. The RoundtripTime and Buffer properties will return zero, and the Options property will return nullptr.
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( "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 ); } }
