|<xref:System.Net.NetworkInformation.PingOptions>|Allows you to configure or retrieve the settings that control how many times the request packet can be forwarded (<xref:System.Net.NetworkInformation.PingOptions.Ttl%2A>), and whether it can be fragmented (<xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> ).|
|<xref:System.Net.NetworkInformation.PingReply>|Contains the results of an ICMP echo request.|
|<xref:System.Net.NetworkInformation.PingException>|Thrown if an unrecoverable error occurs.|
|<xref:System.Net.NetworkInformation.PingCompletedEventArgs>|Contains the data associated with <xref:System.Net.NetworkInformation.Ping.PingCompleted> events, which are raised when a <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> call completes or is canceled.|
|<xref:System.Net.NetworkInformation.PingCompletedEventHandler>|The delegate that provides the callback method invoked when a <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> call completes or is canceled.|
The <xref:System.Net.NetworkInformation.Ping.Send%2A> and <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> methods return the reply in a <xref:System.Net.NetworkInformation.PingReply> object. The <xref:System.Net.NetworkInformation.PingReply.Status%2A?displayProperty=nameWithType> property returns an <xref:System.Net.NetworkInformation.IPStatus> value to indicate the outcome of the request.
When sending the request, you must specify the remote computer. You can do this by providing a host name string, an IP address in string format, or an <xref:System.Net.IPAddress> object.
You can also specify any of the following types of information:
- Data to accompany the request. Specifying `buffer` allows you to learn the amount of time required for a packet of a particular size to travel to and from the remote host and the maximum transmission unit of the network path. (See the <xref:System.Net.NetworkInformation.Ping.Send%2A> or <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> overloads that take a `buffer` parameter.)
- Whether the ICMP Echo packet can be fragmented in transit. (See the <xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> property and the <xref:System.Net.NetworkInformation.Ping.Send%2A> or <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> overloads that take an `options` parameter.)
- How many times routing nodes, such as routers or gateways, can forward the packet before it either reaches the destination computer or is discarded. (See <xref:System.Net.NetworkInformation.PingOptions.Ttl%2A> and the <xref:System.Net.NetworkInformation.Ping.Send%2A> or <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> overloads that take an `options` parameter.)
- The time limit within which the reply must be received. (See the <xref:System.Net.NetworkInformation.Ping.Send%2A> or <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> overloads that take a `timeout` parameter.
The <xref:System.Net.NetworkInformation.Ping> class offers both synchronous and asynchronous methods for sending the request. If your application should block while waiting for a reply, use the <xref:System.Net.NetworkInformation.Ping.Send%2A> methods; these methods are synchronous. If your application should not block, use the asynchronous <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> methods. A call to <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> executes in its own thread that is automatically allocated from the thread pool. When the asynchronous operation completes, it raises the <xref:System.Net.NetworkInformation.Ping.PingCompleted> event. Applications use a <xref:System.Net.NetworkInformation.PingCompletedEventHandler> delegate to specify the method that is called for <xref:System.Net.NetworkInformation.Ping.PingCompleted> events. You must add a <xref:System.Net.NetworkInformation.PingCompletedEventHandler> delegate to the event before calling <xref:System.Net.NetworkInformation.Ping.SendAsync%2A>. The delegate's method receives a <xref:System.Net.NetworkInformation.PingCompletedEventArgs> object that contains a <xref:System.Net.NetworkInformation.PingReply> object that describes the result of the <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> call.
You cannot use the same instance of the <xref:System.Net.NetworkInformation.Ping> class to generate multiple simultaneous ICMP Echo requests. Calling <xref:System.Net.NetworkInformation.Ping.Send%2A> while a <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> call is in progress or calling <xref:System.Net.NetworkInformation.Ping.SendAsync%2A> multiple times before all previous calls have completed causes an <xref:System.InvalidOperationException>.
## Examples
The following code example demonstrates using the <xref:System.Net.NetworkInformation.Ping> class synchronously.

## Remarks
This method is called by the public `Dispose()` method and the <xref:System.ComponentModel.Component.Finalize%2A> method. The public `Dispose()` method invokes the protected <xref:System.Net.NetworkInformation.Ping.Dispose%2A> method with the `disposing` parameter set to `true`. <xref:System.ComponentModel.Component.Finalize%2A> invokes `Dispose` with `disposing` set to `false`.
When the `disposing` parameter is `true`, this method releases all resources held by any managed objects that this <xref:System.Net.NetworkInformation.Ping> object references. This method invokes the `Dispose()` method of each referenced object.

## Remarks
If the ICMP echo reply message is not received within the time specified in the `timeout` parameter, the ICMP echo fails, and the <xref:System.Net.NetworkInformation.PingReply.Status%2A> property is set to <xref:System.Net.NetworkInformation.IPStatus.TimedOut>.
> [!NOTE]
> When specifying very small numbers for `timeout`, the Ping reply can be received even if `timeout` milliseconds have elapsed.
This overload uses default settings for packet fragmentation and packet forwarding. The packet that contains the ICMP echo message can be fragmented in transit if the total packet size exceeds the maximum packet size that can be transmitted by one of the routing nodes between the local and remote computers. To prevent fragmentation, use one of the <xref:System.Net.NetworkInformation.Ping.Send%2A> methods that takes an `options` parameter, and set the <xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> property to `true`. When <xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> is `true` and the total packet size exceeds the maximum packet size that can be transmitted by one of the routing nodes between the local and remote computers, the ICMP echo request fails. When this happens, the <xref:System.Net.NetworkInformation.PingReply.Status%2A> is set to <xref:System.Net.NetworkInformation.IPStatus.PacketTooBig>.
The packet or packet fragments can be forwarded by routing nodes 128 times before being discarded. To change this setting, use a <xref:System.Net.NetworkInformation.Ping.Send%2A> overload that takes an `options` parameter, and set the <xref:System.Net.NetworkInformation.PingOptions.Ttl%2A> property to the desired value. If the packet does not reach its destination after being forwarded the specified number of times, the packet is discarded and the ICMP echo request fails. When this happens, the <xref:System.Net.NetworkInformation.PingReply.Status%2A> is set to <xref:System.Net.NetworkInformation.IPStatus.TtlExpired>.

## Remarks
If the ICMP echo reply message is not received within the time specified in the `timeout` parameter, the ICMP echo fails, and the <xref:System.Net.NetworkInformation.PingReply.Status%2A> property is set to <xref:System.Net.NetworkInformation.IPStatus.TimedOut>.
> [!NOTE]
> When specifying very small numbers for `timeout`, the Ping reply can be received even if `timeout` milliseconds have elapsed.
This overload uses default settings for packet fragmentation and packet forwarding. The packet that contains the ICMP echo message can be fragmented in transit if the total packet size exceeds the maximum packet size that can be transmitted by one of the routing nodes between the local and remote computers. To prevent fragmentation, use one of the <xref:System.Net.NetworkInformation.Ping.Send%2A> methods that takes an `options` parameter, and set the <xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> property to `true`. When <xref:System.Net.NetworkInformation.PingOptions.DontFragment%2A> is `true` and the total packet size exceeds the maximum packet size that can be transmitted by one of the routing nodes between the local and remote computers, the ICMP echo request fails. When this happens, the <xref:System.Net.NetworkInformation.PingReply.Status%2A> is set to <xref:System.Net.NetworkInformation.IPStatus.PacketTooBig>.
The packet or packet fragments can be forwarded by routing nodes 128 times before being discarded. To change this setting, use a <xref:System.Net.NetworkInformation.Ping.Send%2A> overload that takes an `options` parameter, and set the <xref:System.Net.NetworkInformation.PingOptions.Ttl%2A> property to the desired value. If the packet does not reach its destination after being forwarded the specified number of times, the packet is discarded and the ICMP echo request fails. When this happens, the <xref:System.Net.NetworkInformation.PingReply.Status%2A> is set to <xref:System.Net.NetworkInformation.IPStatus.TtlExpired>.
