Public Shared Function EndGetHostByName (asyncResult As IAsyncResult) As IPHostEntry

参数

asyncResult
IAsyncResult

一个 IAsyncResult 实例，该实例通过调用 BeginGetHostByName(String, AsyncCallback, Object) 方法返回。

返回

IPHostEntry

一个 IPHostEntry 对象，该对象包含一个主机的 DNS 信息。

属性
ObsoleteAttribute

例外

ArgumentNullException

asyncResult 为 null。

注解

此方法将阻止，直到操作完成。

若要同步执行此操作，请使用 GetHostByName 方法。

如果 属性 Ipv6Element.Enabled 设置为 true，则 Aliases 此方法不会填充返回的 IPHostEntry 实例的属性，并且始终为空。
