C# .NET의 관리자 IP 도우미 기능

Question

관리되는 IP 도우미 기능을 C# .net으로 변환 할 수 있습니까? 나는 그것이 PInvoke ing에 의해 쓰여 져야한다는 것을 안다. Microsoft

당신에게 감사 할 것이다 : 여기

는 IP 도우미 기능입니다. 여기

은 예입니다

public static TcpTable GetExtendedTcpTable(bool sorted) 
    { 
     List<TcpRow> tcpRows = new List<TcpRow>(); 

     IntPtr tcpTable = IntPtr.Zero; 
     int tcpTableLength = 0; 

     if (IpHelper.GetExtendedTcpTable(tcpTable, ref tcpTableLength, sorted, IpHelper.AfInet, IpHelper.TcpTableType.OwnerPidAll, 0) != 0) 
     { 
      try 
      { 
       tcpTable = Marshal.AllocHGlobal(tcpTableLength); 
       if (IpHelper.GetExtendedTcpTable(tcpTable, ref tcpTableLength, true, IpHelper.AfInet, IpHelper.TcpTableType.OwnerPidAll, 0) == 0) 
       { 
        IpHelper.TcpTable table = (IpHelper.TcpTable)Marshal.PtrToStructure(tcpTable, typeof(IpHelper.TcpTable)); 

        IntPtr rowPtr = (IntPtr)((long)tcpTable + Marshal.SizeOf(table.length)); 
        for (int i = 0; i < table.length; ++i) 
        { 
         tcpRows.Add(new TcpRow((IpHelper.TcpRow)Marshal.PtrToStructure(rowPtr, typeof(IpHelper.TcpRow)))); 
         rowPtr = (IntPtr)((long)rowPtr + Marshal.SizeOf(typeof(IpHelper.TcpRow))); 
        } 
       } 
      } 
      finally 
      { 
       if (tcpTable != IntPtr.Zero) 
       { 
        Marshal.FreeHGlobal(tcpTable); 
       } 
      } 
     } 

     return new TcpTable(tcpRows); 
    } 

`

여기에 기본 기능입니다 :

[DllImport(IpHelper.DllName, SetLastError = true)] 
public static extern uint GetExtendedTcpTable(IntPtr tcpTable, ref int tcpTableLength, bool sort, int ipVersion, TcpTableType tcpTableType, int reserved);

당신은 그

[DllImport("iphlpapi.dll", CharSet=CharSet.Ansi)] 
public static extern int GetAdaptersInfo(IntPtr pAdapterInfo, ref Int64 pBufOutLen); 

[DllImport("iphlpapi.dll", SetLastError=true)] 
static extern uint GetExtendedTcpTable(IntPtr pTcpTable, ref int dwOutBufLen, bool sort, int ipVersion, TCP_TABLE_CLASS tblClass,int reserved);
