示例1: SocketPermission
' Creates a SocketPermission restricting access to and from all URIs.
Dim mySocketPermission1 As New SocketPermission(PermissionState.None)
' The socket to which this permission will apply will allow connections from www.contoso.com.
mySocketPermission1.AddPermission(NetworkAccess.Accept, TransportType.Tcp, "www.contoso.com", 11000)
' Creates a SocketPermission which will allow the target Socket to connect with www.southridgevideo.com.
Dim mySocketPermission2 As New SocketPermission(NetworkAccess.Connect, TransportType.Tcp, "www.southridgevideo.com", 11002)
' Creates a SocketPermission from the union of two SocketPermissions.
Dim mySocketPermissionUnion As SocketPermission = CType(mySocketPermission1.Union(mySocketPermission2), SocketPermission)
' Checks to see if the union was successfully created by using the IsSubsetOf method.
If mySocketPermission1.IsSubsetOf(mySocketPermissionUnion) And mySocketPermission2.IsSubsetOf(mySocketPermissionUnion) Then
Console.WriteLine("This union contains permissions from both mySocketPermission1 and mySocketPermission2")
' Prints the allowable accept URIs to the console.
Console.WriteLine("This union accepts connections on :")
Dim myEnumerator As IEnumerator = mySocketPermissionUnion.AcceptList
While myEnumerator.MoveNext()
Console.WriteLine(CType(myEnumerator.Current, EndpointPermission).ToString())
End While
Console.WriteLine("This union establishes connections on : ")
' Prints the allowable connect URIs to the console.
Console.WriteLine("This union permits connections to :")
myEnumerator = mySocketPermissionUnion.ConnectList
While myEnumerator.MoveNext()
Console.WriteLine(CType(myEnumerator.Current, EndpointPermission).ToString())
End While
End If
