属性值

一个指定地址范围的长整数。

示例

// Display the type of address family supported by the server. If the
// server is IPv6-enabled this value is: InterNetworkV6. If the server
// is also IPv4-enabled there will be an additional value of InterNetwork.
Console.WriteLine("AddressFamily: " + curAdd.AddressFamily.ToString());

// Display the ScopeId property in case of IPV6 addresses.
if(curAdd.AddressFamily.ToString() == ProtocolFamily.InterNetworkV6.ToString())
  Console.WriteLine("Scope Id: " + curAdd.ScopeId.ToString());

' Display the type of address family supported by the server. If the
' server is IPv6-enabled this value is: InterNetworkV6. If the server
' is also IPv4-enabled there will be an additional value of InterNetwork.
Console.WriteLine(("AddressFamily: " + curAdd.AddressFamily.ToString()))

' Display the ScopeId property in case of IPV6 addresses.
If curAdd.AddressFamily.ToString() = ProtocolFamily.InterNetworkV6.ToString() Then
  Console.WriteLine(("Scope Id: " + curAdd.ScopeId.ToString()))
End If

注解

更改的含义 ScopeId ，具体取决于所使用的上下文。

• 链接本地地址。 在连接到单独链接的多个接口的主机上，可以将同一个链接本地地址分配给多个接口。 为了消除这种歧义，范围标识符用于指定交换消息的接口。

• 站点本地地址。 主机可以连接到多个站点。 在这种情况下，范围标识符用于指示要与之通信的特定站点。

用于指定具有地址的 ScopeId 表示法为 Address%ScopeId。 例如： FE80::5EFE:192.168.41.30%2.
