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)

'Declaration
Public ReadOnly Property AcceptList As IEnumerator
'Usage
Dim instance As SocketPermission
Dim value As IEnumerator

value = instance.AcceptList

/** @property */
public IEnumerator get_AcceptList ()

public function get AcceptList () : IEnumerator

Property Value

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")
