定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
提供本地计算机的 Internet 协议版本 4 (IPv4) 统计数据。
public:
 abstract System::Net::NetworkInformation::IPGlobalStatistics ^ GetIPv4GlobalStatistics();public abstract System.Net.NetworkInformation.IPGlobalStatistics GetIPv4GlobalStatistics();abstract member GetIPv4GlobalStatistics : unit -> System.Net.NetworkInformation.IPGlobalStatisticsPublic MustOverride Function GetIPv4GlobalStatistics () As IPGlobalStatistics返回
一个 IPGlobalStatistics 对象,提供本地计算机的 IPv4 流量统计数据。
例外
调用 Win32 函数 GetIpStatistics 失败。
示例
下面的代码示例显示本地计算机的 IP 统计信息。
public static void ShowIPStatistics(NetworkInterfaceComponent version)
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = null;
    switch (version)

            Console.WriteLine("{0}IPv6 Statistics ",Environment.NewLine);
            break;
        default:
            throw new ArgumentException("version");
        //    break;

        ipstat.OutputPacketsWithNoRoute);
    Console.WriteLine("      Routing Entry Discards .............. : {0}",
        ipstat.OutputPacketRoutingDiscards);
    Console.WriteLine("");
    Console.WriteLine("  Reassembly Data:");
    Console.WriteLine("      Reassembly Timeout .................. : {0}",
        ipstat.PacketReassemblyTimeout);
    Console.WriteLine("      Reassemblies Required ............... : {0}",
        ipstat.PacketReassembliesRequired);
    Console.WriteLine("      Packets Reassembled ................. : {0}",
        ipstat.PacketsReassembled);
    Console.WriteLine("      Packets Fragmented .................. : {0}",
        ipstat.PacketsFragmented);
    Console.WriteLine("      Fragment Failures ................... : {0}",
        ipstat.PacketFragmentFailures);
    Console.WriteLine("");
}
注解
IPv4 是一种网络层协议,负责将数据包从源计算机路由到目标。
