The Ping component enables easy Ping functionality in an application.

For a list of all members of this type, see Ping members.

Syntax

[Visual Basic]
<LicenseProviderAttribute(PingLicenseProvider)>
Public Class Ping 
   Inherits Component

[C#]
[LicenseProviderAttribute(PingLicenseProvider)]
public class Ping : Component

[C++]
[LicenseProviderAttribute(PingLicenseProvider)]
public __gc class Ping : public Component

[C++/CLI]
[LicenseProviderAttribute(PingLicenseProvider)]
public ref class Ping : public Component

Remarks

The Ping component is used to determine if a host is reachable by sending an ICMP echo. This is performed by sending an ICMP echo request message to a host, receiving the ICMP echo reply, and calculating the time difference. Both asynchronous and synchronous use is fully supported. In addition, you can choose to ping with an ICMP packet (the default), a UDP packet, or a TCP connection attempt.

Example

The following example demonstrates a default ping operation.

[Visual Basic]

Try

   ' Ping a host

   Dim er As EchoResult = Ping1.Send("www.dart.com")



   ' Display results

   Debug.WriteLine("Response from www.dart.com")

   Debug.WriteLine("Sequence number " + er.Sequence)

   Debug.WriteLine("Delay " + er.ResponseTime)

   Debug.WriteLine("Bytes " + er.Data.Length)



Catch ex as Exception

    Debug.WriteLine("Cannot reach www.dart.com")

End Try

[C#]



try

{

  // Ping a host

  EchoResult er = ping1.Send("www.dart.com");



  // Display results

  Debug.WriteLine("Response from www.dart.com");

  Debug.WriteLine("Sequence number " + er.Sequence);

  Debug.WriteLine("Delay " + er.ResponseTime);

  Debug.WriteLine("Bytes " + er.Data.Length);

}
catch(Exception ex)

{

  Debug.WriteLine("Cannot reach www.dart.com");
