public:
 static System::Threading::Tasks::Task<cli::array <System::Net::IPAddress ^> ^> ^ GetHostAddressesAsync(System::String ^ hostNameOrAddress);
public static System.Threading.Tasks.Task<System.Net.IPAddress[]> GetHostAddressesAsync (string hostNameOrAddress);
static member GetHostAddressesAsync : string -> System.Threading.Tasks.Task<System.Net.IPAddress[]>
Public Shared Function GetHostAddressesAsync (hostNameOrAddress As String) As Task(Of IPAddress())
Parameters
hostNameOrAddress
String String String String

The host name or IP address to resolve.

Returns

Returns Task<TResult>.

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.

Exceptions

An error is encountered when resolving hostNameOrAddress.

hostNameOrAddress is an invalid IP address.

Remarks

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.
