Hello lifetime,
Welcome to the forum and I am happy to assist you.

I suspect the path is not correct. Instead of writing the code as

private string path         = "d:\ninjatest\order.txt";

please append it as

private string path         = @"d:\ninjatest\order.txt";

Please refer to this sample code which demonstrates how to read from a text file.
