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

No code example is currently available or this language may not be supported.
SocketPermission* socketPermission1 = new SocketPermission(PermissionState::Unrestricted);

// Create a 'SocketPermission' Object* for two ip addresses.
SocketPermission* socketPermission2 = new SocketPermission(PermissionState::None);

// 'SocketPermission' Object* for 'Connect' permission
SecurityElement* securityElement1 = new SecurityElement(S"ConnectAccess");
// Format to specify ip address are <ip-address>#<port>#<transport-type>
// First 'SocketPermission' ip-address is '' for 'All' transport types and for 'All' ports for the ip-address.
SecurityElement* securityElement2 = new SecurityElement(S"URI", S"");
// Second 'SocketPermission' ip-address is '' for 'All' transport types and for 'All' ports for the ip-address.
SecurityElement* securityElement3 = new SecurityElement(S"URI", S"");

// Obtain a 'SocketPermission' Object* using 'FromXml' method.

// Create another 'SocketPermission' Object* with two ip addresses.
// First 'SocketPermission' ip-address is '' for 'All' transport types and for 'All' ports for the ip-address.
SocketPermission* socketPermission3 = new SocketPermission(NetworkAccess::Connect,

// Second 'SocketPermission' ip-address is '' for 'All' transport types and for 'All' ports for the ip-address.
