IPv6InterfaceProperties.Mtu 属性

定义

命名空间:

System.Net.NetworkInformation

程序集:

System.Net.NetworkInformation.dll

Source:

IPv6InterfaceProperties.cs

获取此网络接口的最大传输单位 (MTU)。

public:

public abstract int Mtu { get; }

member this.Mtu : int

Public MustOverride ReadOnly Property Mtu As Integer

属性值

Int32

用于指定 MTU 的 Int64 值。

示例

下面的代码示例获取对象 IPv6InterfaceProperties 并显示其数据。

void DisplayIPv6NetworkInterfaces()

   array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   Console::WriteLine( "IPv6 interface information for {0}.{1}", 
       properties->HostName, properties->DomainName );

注解

网络接口的 MTU 是可以传输的最大数据包。 它以八进制数 (8 位字节) 度量。
