範例

      statistics->TimeExceededMessagesSent, 
      statistics->TimeExceededMessagesReceived );
}

    Dim statistics As IcmpV4Statistics = properties.GetIcmpV4Statistics()

備註

封包的躍點限制決定在捨棄之前可以轉送的次數。 每次轉送封包時，其躍點限制值會遞減一。 當躍點限制達到零或路由器收到其躍點限制設為零的封包時，封包會被捨棄，而封包的來源會收到「超過時間」訊息，指出初始躍點限制太小，或封包在路由迴圈中攔截到。
