In C# you can do that:

var filename = @"C:\path\to\my\file.txt";
var file = new Uri(filename).AbsoluteUri;
// file is "file:///C:/path/to/my/file.txt"

How can I do that in D?

@safe void henforce(HRESULT hres, lazy string msg = null, string 
file = __FILE__, size_t line = __LINE__)

    if (hres != S_OK)
        throw new WindowsException(hres, msg, file, line);
}

    import std.path : absolutePath;
    import std.utf : toUTF16z;

    henforce(urlCreateFromPath(path.absolutePath.toUTF16z, 
buf.ptr, &size, 0));
    return buf[0..size].idup;
}
