PingOptions::Ttl Property
Gets or sets the number of routing nodes that can forward the Ping data before it is discarded.
Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | The value specified for a set operation is less than or equal to zero. |
As gateways and routers transmit packets through a network, they decrement the current Time-to-Live (TTL) value found in the packet header. If the TTL value reaches zero, the packet is deemed undeliverable and is discarded. This option is useful if you want to test the number of routers and gateways used to transmit the data.
The following code example demonstrates setting the value of this property using a PingOptions constructor, and then displaying the value.
// Set options for transmission: // The data can go through 64 gateways or routers // before it is destroyed, and the data packet // cannot be fragmented. PingOptions ^ options = gcnew PingOptions( 64,true ); Console::WriteLine( "Time to live: {0}", options->Ttl ); Console::WriteLine( "Don't fragment: {0}", options->DontFragment );
