LPWSTR comparison

How do I properly deal with the if statement in this example:

int n_args = 0;
int i;
LPWSTR *args = CommandLineToArgvW(GetCommandLineW(), &n_args);
if (args)
{
    if (n_args >= 2)
    {
        for (i = 1; i < n_args; i++)
        {
            std::cout << args[i] << "\n";
            if (args[i] == L"/D") // <-- here
            {
                std::cout << "Condition met\n";
            }
        }
    }
}

The first std::cout shows that the command line parameter has been passed, but the following if statement fails.
