member this.DhcpServerAddresses : System.Net.NetworkInformation.IPAddressCollection

Public MustOverride ReadOnly Property DhcpServerAddresses As IPAddressCollection

屬性值

IPAddressCollection

IPAddressCollection，包含 DHCP 伺服器的位址資訊，但如果找不到任何伺服器則為空陣列。

屬性

UnsupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示本機計算機上的網路介面 DHCP 位址資訊。

備註

動態主機設定通訊協定 (DHCP) 可讓計算機從 DHCP 伺服器取得網路位址，而不是使用靜態 (固定) 網路位址。 DHCP 伺服器不會永久指派位址;相反地，它會暫時使用一些可用的位址之一給計算機。
