SocketPermission* socketPermission1 = 
   new SocketPermission(PermissionState::Unrestricted);

// Create a 'SocketPermission' Object* for two ip addresses.
SocketPermission* socketPermission2 = new SocketPermission(PermissionState::None);
SecurityElement*  securityElement1 = socketPermission2->ToXml();
// 'SocketPermission' Object* for 'Connect' permission
SecurityElement* securityElement2 = new SecurityElement(S"ConnectAccess");
// Format to specify ip address are <ip-address>#<port>#<transport-type>
// First 'SocketPermission' ip-address is '192.168.144.238' for 'All' transport types and
// for 'All'ports for the ip-address.
SecurityElement* securityElement3 = 
   new SecurityElement(S"URI", S"192.168.144.238#-1#3");
// Second 'SocketPermission' ip-address is '192.168.144.240' for 'All' transport types and

// Obtain a 'SocketPermission' Object* using 'FromXml' method.
socketPermission2->FromXml(securityElement1);

Console::WriteLine(S"\nDisplays the result of FromXml method : \n");
Console::WriteLine(socketPermission2);

// Create another 'SocketPermission' Object* with two ip addresses.
// First 'SocketPermission' ip-address is '192.168.144.238' for 'All' transport types and for 'All' ports for the ip-address.

// Demand that the calling method have the requsite socket permission.
