OperationalStatus 枚举
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。
指定网络接口的操作状态。
public enum class OperationalStatuspublic enum OperationalStatustype OperationalStatus = Public Enum OperationalStatus- 继承
字段
| 名称 | 值 | 说明 |
|---|---|---|
| Dormant | 5 | 网络接口不处于传输数据包的状态；它正等待外部事件。 |
| Down | 2 | 网络接口无法传输数据包。 |
| LowerLayerDown | 7 | 网络接口无法传输数据包，因为它运行在一个或多个其他接口之上，而这些“低层”接口中至少有一个已关闭。 |
| NotPresent | 6 | 由于缺少组件（通常为硬件组件），网络接口无法传输数据包。 |
| Testing | 3 | 网络接口正在运行测试。 |
| Unknown | 4 | 网络接口的状态未知。 |
| Up | 1 | 网络接口已运行，可以传输数据包。 |
示例
下面的代码示例显示本地计算机上所有接口的摘要。
void ShowInterfaceSummary()
{
array<NetworkInterface^>^interfaces = NetworkInterface::GetAllNetworkInterfaces();
System::Collections::IEnumerator^ myEnum5 = interfaces->GetEnumerator();
while ( myEnum5->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum5->Current);
Console::WriteLine( "Name: {0}", adapter->Name );
Console::WriteLine( adapter->Description );
Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
Console::WriteLine( " Interface type .......................... : {0}",
adapter->NetworkInterfaceType );
Console::WriteLine( " Operational status ...................... : {0}", adapter->OperationalStatus );
String^ versions = "";
// Create a display string for the supported IP versions.
if ( adapter->Supports( NetworkInterfaceComponent::IPv4 ) )
{
versions = "IPv4";
}
if ( adapter->Supports( NetworkInterfaceComponent::IPv6 ) )
{
if ( versions->Length > 0 )
{
versions = String::Concat( versions, " " );
}
versions = String::Concat( versions, "IPv6" );
}
Console::WriteLine( " IP version .............................. : {0}", versions );
Console::WriteLine();
}
Console::WriteLine();
}
public static void ShowInterfaceSummary()
{
NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in interfaces)
{
Console.WriteLine ("Name: {0}", adapter.Name);
Console.WriteLine(adapter.Description);
Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
Console.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType);
Console.WriteLine(" Operational status ...................... : {0}",
adapter.OperationalStatus);
string versions ="";
// Create a display string for the supported IP versions.
if (adapter.Supports(NetworkInterfaceComponent.IPv4))
{
versions = "IPv4";
}
if (adapter.Supports(NetworkInterfaceComponent.IPv6))
{
if (versions.Length > 0)
{
versions += " ";
}
versions += "IPv6";
}
Console.WriteLine(" IP version .............................. : {0}", versions);
Console.WriteLine();
}
Console.WriteLine();
}
注解
此枚举定义 属性的有效值 OperationalStatus 。
