pascal-snake-case	Returns the input text in Pascal_Snake case, capitalizing each word and joining them with underscores. Returns empty text when the input is null, empty, blank, or a zero-length array.
path-case	Returns the input text in path/case, lowercasing words and joining them with slashes. Returns empty text when the input is null, empty, blank, or a zero-length array.
screaming-snake-case	Returns the input text in SCREAMING_SNAKE_CASE, uppercasing words and joining them with underscores. Returns empty text when the input is null, empty, blank, or a zero-length array.
sentence-case	Returns the input text in sentence case by capitalizing the first word while preserving the remaining content. Words containing dots, ampersands, or uppercase letters beyond the first character are treated as already correctly cased and preserved as-is (for example example.com, AT&T, and iTunes). Returns null when the input is null, DBNull, (null), or a zero-length array.
snake-case	Returns the input text in snake_case, lowercasing words and joining them with underscores. Returns empty text when the input is null, empty, blank, or a zero-length array.
swap-case	Returns the input text with lowercase characters converted to uppercase and uppercase characters converted to lowercase. Returns null when the input is null, DBNull, (null), or a zero-length array.
title-case	Returns the input text in title case, capitalizing words while keeping small words lowercase only when they are neither first nor last and do not follow a colon. The first and last words are always capitalized, and a small word after a colon is capitalized. Words containing dots, ampersands, or uppercase letters beyond the first character are treated as already correctly cased and preserved as-is (for example example.com, Q&A, and iTunes). Returns null when the input is null, DBNull, (null), or a zero-length array.
train-case	Returns the input text in Train-Case, capitalizing each word and joining them with hyphens. Returns empty text when the input is null, empty, blank, or a zero-length array.
upper	Returns the input text converted to uppercase using invariant culture rules. Returns null when the input is null, DBNull, (null), or a zero-length array.
