Boolean 值，指定是否已啟用封包轉送。

屬性

UnsupportedOSPlatformAttribute

範例

下列程式代碼範例會顯示此屬性的值。

void ShowIPStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Forwarding enabled ...................... : {0}", 
      ipstat->ForwardingEnabled );
   Console::WriteLine( "  Interfaces .............................. : {0}", 
      ipstat->NumberOfInterfaces );
   Console::WriteLine( "  IP addresses ............................ : {0}", 
      ipstat->NumberOfIPAddresses );
   Console::WriteLine( "  Routes .................................. : {0}", 
      ipstat->NumberOfRoutes );
   Console::WriteLine( "  Default TTL ............................. : {0}", 
      ipstat->DefaultTtl );
}

public static void ShowIPStatistics()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Forwarding enabled ...................... : {0}",
        ipstat.ForwardingEnabled);
    Console.WriteLine("  Interfaces .............................. : {0}",
        ipstat.NumberOfInterfaces);
    Console.WriteLine("  IP addresses ............................ : {0}",
        ipstat.NumberOfIPAddresses);
    Console.WriteLine("  Routes .................................. : {0}",
        ipstat.NumberOfRoutes);
    Console.WriteLine("  Default TTL ............................. : {0}",
        ipstat.DefaultTtl);
}

Public Shared Sub ShowIPStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Forwarding enabled ...................... : {0}", ipstat.ForwardingEnabled)
    Console.WriteLine("  Interfaces .............................. : {0}", ipstat.NumberOfInterfaces)
    Console.WriteLine("  IP addresses ............................ : {0}", ipstat.NumberOfIPAddresses)
    Console.WriteLine("  Routes .................................. : {0}", ipstat.NumberOfRoutes)
    Console.WriteLine("  Default TTL ............................. : {0}", ipstat.DefaultTtl)

End Sub

備註

這個值會決定計算機是否轉送目的地為另一部計算機的IP數據報。 一般而言，路由器會轉送封包和主計算機不會。
