IPHostEntry.HostName 속성

정의

네임스페이스:

System.Net

어셈블리:

System.Net.NameResolution.dll

Source:

IPHostEntry.cs

호스트의 DNS 이름을 가져오거나 설정합니다.

public:
 property System::String ^ HostName { System::String ^ get(); void set(System::String ^ value); };

public string HostName { get; set; }

member this.HostName : string with get, set

Public Property HostName As String

속성 값

String

서버의 기본 호스트 이름이 포함된 문자열입니다.

예제

다음 예제에서는 HostName 속성을 기본 호스트 이름을 검색 합니다.

void GetIpAddressList( String^ hostString )
{
   try
   {
      // Get 'IPHostEntry' object containing information
      // like host name, IP addresses, aliases for a host.

      Console::WriteLine( "Host name : {0}", hostInfo->HostName );
      Console::WriteLine( "IP address List : " );
      for ( int index = 0; index < hostInfo->AddressList->Length; index++ )
         Console::WriteLine( hostInfo->AddressList[ index ] );

설명

HostName 속성을 서버에 대 한 기본 호스트 이름을 포함 합니다. 사용할 수는 서버에 대 한 DNS 항목 추가 별칭을 정의 하는 경우는 Aliases 속성입니다.
