Sends an Internet Control Message Protocol (ICMP) echo message with the specified data buffer to the computer that has the specified IPAddress, and receives a corresponding ICMP echo reply message from that computer as an asynchronous operation. This overload allows you to specify a time-out value for the operation, a buffer to use for send and receive, and control fragmentation and Time-to-Live values for the ICMP echo message packet. |
| SendPingAsync(String, Int32, Byte[], PingOptions) |
Sends an Internet Control Message Protocol (ICMP) echo message with the specified data buffer to the specified computer, and receive a corresponding ICMP echo reply message from that computer as an asynchronous operation. This overload allows you to specify a time-out value for the operation, a buffer to use for send and receive, and control fragmentation and Time-to-Live values for the ICMP echo message packet. |
| SendPingAsync(IPAddress, TimeSpan, Byte[], PingOptions, CancellationToken) |
Sends an Internet Control Message Protocol (ICMP) echo message with the specified data buffer to the computer that has the specified IPAddress, and receives a corresponding ICMP echo reply message from that computer as an asynchronous operation. This overload allows you to specify a time-out value for the operation, a buffer to use for send and receive, control fragmentation and Time-to-Live values, and a CancellationToken for the ICMP echo message packet. |
Remarks
The IP address returned by any of the SendPingAsync methods can originate from a malicious remote computer. Do not connect to the remote computer using this. Use DNS to determine the IP address of the machine to which you want to connect.
