Sorry, C#

Please help.
First of all, places of "expected" and "but was" in random test are switched
Test Failed
Expected string length 233 but was 220. Strings differ at index 0.
Expected: "hello warriorsC\n\nFF.."
But was: "\nC\n\nFF..."

Edge and stripcomments tests return "passed"
Seems to be my solution returns right answer but random "expected" always has few extra "\n" on start
Expected: "C\n\n\n\nA..."
But was: "\n\n\nC\n\n\n\A..."
