如何在.NET中更改計算機的主DNS後綴？

Question

我正在爲新PC的自動配置應用程序。我設法以編程方式設置除計算機的主DNS後綴之外的所有必需參數（請記住，這與網絡連接默認DNS後綴不同）。

任何幫助？

更新：這是要求的類別，用於設置PC的IP，子網，網關和DNS。 http://pastebin.com/fHACwwDV

它僅在具有1個網絡接口的系統中測試過，我不知道當有更多的NIC時它將如何表現。哦，這是在製品，所以現在除了拋出異常之外沒有執行任何錯誤處理。

Answer 1

對msdn的搜索，看起來像你需要使用SetComputerNameEx。

pinvoke.net spells out what you'll need to do to access this from C#.

Answer 2

耶，它的工作。當然，我一如既往愚蠢，因爲我已經設置了主機名。 下面是在vb.net主機/後綴改變全碼：

Private Enum COMPUTER_NAME_FORMAT As Integer 
    ComputerNameNetBIOS = 0 
    ComputerNameDnsHostname = 1 
    ComputerNameDnsDomain = 2 
    ComputerNameDnsFullyQualified = 3 
    ComputerNamePhysicalNetBIOS = 4 
    ComputerNamePhysicalDnsHostname = 5 
    ComputerNamePhysicalDnsDomain = 6 
    ComputerNamePhysicalDnsFullyQualified = 7 
End Enum 

Public Const MAX_COMPUTERNAME_LENGTH As Int32 = 31 

<DllImport("kernel32.dll", CharSet:=CharSet.Ansi, SetLastError:=True)> _ 
Private Shared Function SetComputerNameEx(_ 
    ByVal NameType As COMPUTER_NAME_FORMAT, _ 
    <MarshalAs(UnmanagedType.LPStr)> ByVal lpBuffer As String) As Integer 
End Function 

Public Function SetNewName(ByVal Computername As String, ByVal DNSSuffix As String) As Boolean 
    If NetworkSet.SetComputerNameEx(COMPUTER_NAME_FORMAT.ComputerNamePhysicalDnsHostname, _ 
     Computername & Convert.ToChar(0)) = 0 Then 
     Throw New Win32Exception 
    End If 
    If NetworkSet.SetComputerNameEx(COMPUTER_NAME_FORMAT.ComputerNamePhysicalDnsDomain, _ 
     DNSSuffix & Convert.ToChar(0)) = 0 Then 
     Throw New Win32Exception 
    End If 

End Function
