Shitty Code Spagetti Говнокод

Набрел тут на кошмарный код. Проверил по Code Metrics (есть такая вкусность в Visual Studio), индекс поддержки - желтый, значение 14 (должен быть как минимум 20, а лучше - стремиться к 100). Цикломатическая сложность кода (зависит от вложенности условных операторов и циклов) - 58, должна быть не более 15.

Весь код привожу под катом.
