A good place to start for network statistics would be the GetIpStatisticscall in the Windows IPHelper functions.
Windows IPHelper 函数中的GetIpStatistics调用是开始网络统计的好地方。
There are a couple of other approaches that are possibly more portable:-
还有一些其他方法可能更便携：-
- SNMP. Requires SNMP to be enabled on the computer, but can obviously be used to retrieve statistics for remote computers also.
- Pipe the output of 'netstat' into your application, and unpick the values from the text.
- 网络管理协议。需要在计算机上启用 SNMP，但显然也可用于检索远程计算机的统计信息。
- 将“netstat”的输出通过管道传输到您的应用程序中，并从文本中取消选择值。

The WMI will provide those readings:
WMI 将提供这些读数：
SELECT * FROM Win32_PerfFormattedData_Tcpip_IP
SELECT * FROM Win32_PerfFormattedData_Tcpip_TCP
SELECT * FROM Win32_PerfFormattedData_Tcpip_UDP
SELECT * FROM Win32_PerfFormattedData_Tcpip_ICMP
SELECT * FROM Win32_PerfFormattedData_Tcpip_Networkinterface
These classes are available on Windows XP or newer. You may have to resign to the matching "Win32_PerfRawData" classes on Windows 2000, and do a little bit more of math before you can display the output.
这些类在 Windows XP 或更新版本上可用。您可能不得不放弃 Windows 2000 上匹配的“Win32_PerfRawData”类，并在显示输出之前做更多的数学运算。
Find documentation on all of themin the MSDN.
在 MSDN 中查找有关所有这些的文档。

Let me answer to myself, as I asked the same on another forum.
让我自己回答，因为我在另一个论坛上问过同样的问题。
WMI is good, but it's easier to use IpHlpApi instead:
WMI 很好，但使用 IpHlpApi 更容易：
#include <winsock2.h>
#include <iphlpapi.h>
int main(int argc, char *argv[])
{
PMIB_IFTABLE pIfTable;
MIB_IFROW ifRow;
PMIB_IFROW pIfRow = &ifRow;
DWORD dwSize = 0;
// first call returns the buffer size needed
DWORD retv = GetIfTable(pIfTable, &dwSize, true);
if (retv != ERROR_INSUFFICIENT_BUFFER)
WriteErrorAndExit(retv);
pIfTable = (MIB_IFTABLE*)malloc(dwSize);
retv = GetIfTable(pIfTable, &dwSize, true);
if (retv != NO_ERROR)
WriteErrorAndExit(retv);
// Get index
int i,j;
printf("\tNum Entries: %ld\n\n", pIfTable->dwNumEntries);
for (i = 0; i < (int) pIfTable->dwNumEntries; i++)
{
pIfRow = (MIB_IFROW *) & pIfTable->table[i];
printf("\tIndex[%d]:\t %ld\n", i, pIfRow->dwIndex);
printf("\tInterfaceName[%d]:\t %ws", i, pIfRow->wszName);
printf("\n");
printf("\tDescription[%d]:\t ", i);
for (j = 0; j < (int) pIfRow->dwDescrLen; j++)
printf("%c", pIfRow->bDescr[j]);
printf("\n");

Szia,
西娅，
from http://en.wikipedia.org/wiki/Netstat
来自http://en.wikipedia.org/wiki/Netstat
On the Windows platform, netstat information can be retrieved by calling the GetTcpTable and GetUdpTable functions in the IP Helper API, or IPHLPAPI.DLL. Information returned includes local and remote IP addresses, local and remote ports, and (for GetTcpTable) TCP status codes. In addition to the command-line netstat.exe tool that ships with Windows, there are GUI-based netstat programs available. On the Windows platform, this command is available only if the Internet Protocol (TCP/IP) protocol is installed as a component in the properties of a network adapter in Network Connections.
在Windows 平台上，可以通过调用IP Helper API 或IPHLPAPI.DLL 中的GetTcpTable 和GetUdpTable 函数来检索netstat 信息。返回的信息包括本地和远程 IP 地址、本地和远程端口以及（对于 GetTcpTable）TCP 状态代码。除了 Windows 附带的命令行 netstat.exe 工具之外，还有基于 GUI 的 netstat 程序可用。在 Windows 平台上，仅当 Internet 协议 (TCP/IP) 协议作为组件安装在网络连接的网络适配器属性中时，此命令才可用。

You might find a feasable WMI performance counter, e.g. Win32_PerfRawData_Tcpip_NetworkInterface.
您可能会找到一个可行的WMI 性能计数器，例如Win32_PerfRawData_Tcpip_NetworkInterface。

As above answers suggest, WMI performance counters contains some data. Just be aware that in later versions of windows the perf counters are broken down in v4 vs v6 so the queries are:
如上所述，WMI 性能计数器包含一些数据。请注意，在更高版本的 Windows 中，性能计数器在 v4 与 v6 中被分解，因此查询是：
SELECT * FROM Win32_PerfFormattedData_Tcpip_IPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_IPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_TCPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_TCPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_UDPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_UDPv4
SELECT * FROM Win32_PerfFormattedData_Tcpip_ICMP
SELECT * FROM Win32_PerfFormattedData_Tcpip_ICMP
SELECT * FROM Win32_PerfFormattedData_Tcpip_IPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_IPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_TCPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_TCPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_UDPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_UDPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_ICMPv6
SELECT * FROM Win32_PerfFormattedData_Tcpip_ICMPv6

See Google Groups, original netstats source code has been posted many times (win32 api)
看Google Groups，原来的netstats源码已经贴了很多次了（win32 api）
