GetExtendedTcpTable 不返回与 netstat -ano 相同的结果

我使用此代码来获取我的电脑中打开的端口的列表以及使用每个端口的应用程序。

string Port::GetListOfTcpPorts()

{
    string ApplicationName = "";
    string result = "";
    string aux = "";
    string RemotePort = "";
    DWORD (WINAPI *pGetExtendedTcpTable)(
  PVOID pTcpTable,
  PDWORD pdwSize,
  BOOL bOrder,
  ULONG ulAf,
  TCP_TABLE_CLASS TableClass,
  ULONG Reserved
);
    MIB_TCPTABLE_OWNER_PID *pTCPInfo;
    MIB_TCPROW_OWNER_PID *owner;
    DWORD size;
    DWORD dwResult;

    HMODULE hLib = LoadLibrary("iphlpapi.dll");

    pGetExtendedTcpTable = (DWORD (WINAPI *)(PVOID,PDWORD,BOOL,ULONG,TCP_TABLE_CLASS,ULONG))
        GetProcAddress(hLib, "GetExtendedTcpTable");

    dwResult = pGetExtendedTcpTable(NULL,       &size, false, AF_INET, TCP_TABLE_OWNER_PID_LISTENER, 0);
    pTCPInfo = (MIB_TCPTABLE_OWNER_PID*)malloc(size);
    dwResult = pGetExtendedTcpTable(pTCPInfo,   &size, false, AF_INET, TCP_TABLE_OWNER_PID_LISTENER, 0);       
   for (DWORD dwLoop = 0; dwLoop < pTCPInfo->dwNumEntries; dwLoop++)
    {
        owner = &pTCPInfo->table[dwLoop];      
        ApplicationName = GetNameByPID(owner->dwOwningPid);
        OpenedPort = convertInt(ntohs(owner->dwLocalPort));         
        RemotePort = convertInt(ntohs(owner->dwRemotePort));
        aux = "TCP ; " + OpenedPort + ";"+ RemotePort+";"+ ApplicationName + "\n";
        result = result + aux;

    }
    return result;
}

但是，如果我将结果与netstat -ano此函数不返回所有 TCP 端口。

Use TCP_TABLE_OWNER_PID_ALL代替TCP_TABLE_OWNER_PID_LISTENER您将获得所有 TCP 端口。
