NetworkInterface.IsReceiveOnly 属性
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。
获取一个 Boolean 值，该值指示网络接口是否设置为仅接收数据包。
public:
virtual property bool IsReceiveOnly { bool get(); };public:
abstract property bool IsReceiveOnly { bool get(); };public virtual bool IsReceiveOnly { get; }public abstract bool IsReceiveOnly { get; }member this.IsReceiveOnly : boolPublic Overridable ReadOnly Property IsReceiveOnly As BooleanPublic MustOverride ReadOnly Property IsReceiveOnly As Boolean属性值
true 如果接口仅接收网络流量，则为否则，为 false.
例外
此属性在运行Windows XP之前的操作系统的计算机上无效。
示例
下面的代码示例显示本地计算机上所有接口的摘要。
public static void DisplayTypeAndAddress()
{
IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
Console.WriteLine("Interface information for {0}.{1} ",
computerProperties.HostName, computerProperties.DomainName);
foreach (NetworkInterface adapter in nics)
{
IPInterfaceProperties properties = adapter.GetIPProperties();
Console.WriteLine(adapter.Description);
Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
Console.WriteLine(" Interface type .......................... : {0}", adapter.NetworkInterfaceType);
Console.WriteLine(" Physical Address ........................ : {0}",
adapter.GetPhysicalAddress().ToString());
Console.WriteLine(" Is receive only.......................... : {0}", adapter.IsReceiveOnly);
Console.WriteLine(" Multicast................................ : {0}", adapter.SupportsMulticast);
Console.WriteLine();
}
}

Dim computerProperties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
Dim nics As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()

Dim adapter As NetworkInterface
For Each adapter In nics

Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, "="c))

Console.WriteLine(" Multicast................................ : {0}", adapter.SupportsMulticast)
Next adapter
