Returns the Internet Protocol (IP) addresses for the specified host as an asynchronous operation.
Assembly: System (in System.dll)
[HostProtectionAttribute(SecurityAction::LinkDemand, ExternalThreading = true)] public: static Task<array<IPAddress^>^>^ GetHostAddressesAsync( String^ hostNameOrAddress )
- Type: System::String
The host name or IP address to resolve.
Return ValueType: System.Threading.Tasks::Task<array<IPAddress>>
The task object representing the asynchronous operation. The Result property on the task object returns an array of type IPAddress that holds the IP addresses for the host that is specified by the hostNameOrAddress parameter.
This operation will not block. The returned Task<TResult> object will complete after the hostNameOrAddress has been resolved.
This method queries a DNS server for the IP addresses associated with a host name. If hostNameOrAddress is an IP address, this address is returned without querying the DNS server.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
