SocketPermission.AcceptList Property

Gets a list of EndpointPermission instances that identifies the endpoints that can be accepted under this permission instance.

Namespace:  System.Net
Assembly:  System (in System.dll)

Public ReadOnly Property AcceptList As IEnumerator

Property Value

Type: System.Collections.IEnumerator
An instance that implements the IEnumerator interface that contains EndpointPermission instances.

The following example uses the AcceptList property to return a list of endpoints to which accept privileges are granted.

' 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
