Examples

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

C#

// Creates a SocketPermission restricting access to and from all URIs.
SocketPermission mySocketPermission1 = 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.
SocketPermission mySocketPermission2 =
                           new SocketPermission(NetworkAccess.Connect, TransportType.Tcp, "www.southridgevideo.com", 11002);

// Creates a SocketPermission from the union of two SocketPermissions.
SocketPermission mySocketPermissionUnion =
                           (SocketPermission)mySocketPermission1.Union(mySocketPermission2);

// Checks to see if the union was successfully created by using the IsSubsetOf method.
if (mySocketPermission1.IsSubsetOf(mySocketPermissionUnion) &&
      mySocketPermission2.IsSubsetOf(mySocketPermissionUnion)){
     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 :");

     IEnumerator myEnumerator = mySocketPermissionUnion.AcceptList;
  while (myEnumerator.MoveNext()) {
          Console.WriteLine(((EndpointPermission)myEnumerator.Current).ToString());
       }

        // Prints the allowable connect URIs to the console.
     Console.WriteLine("This union permits connections to :");

     myEnumerator = mySocketPermissionUnion.ConnectList;
  while (myEnumerator.MoveNext()) {
          Console.WriteLine(((EndpointPermission)myEnumerator.Current).ToString());
       }
      }
