PingOptions.Ttl Property

Gets or sets the number of routing nodes that can forward the Ping data before it is discarded.

Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

member Ttl : int with get, set

Property Value

Type: System.Int32
An Int32 value that specifies the number of times the Ping data packets can be forwarded. The default is 128.

ExceptionCondition
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.
