ModelValidatorsExtensionsIsNameValid Method

Check whether the name property has been properly filled in. A name should satisfy these requirements: No digits (0-9): Names should not contain any numerical characters. No forbidden special characters: Characters like @, !, ?, #, ,, $, _, &, (, ) are not allowed. Only valid punctuation is allowed: Apostrophes (') and hyphens (-) are permitted but must be used correctly (e.g., no double hyphens like Anne--Marie and no trailing hyphens like Carlos-Name-). No consecutive spaces: A name should not have multiple spaces in a row (e.g., Li Wei). No leading or trailing spaces: Names should not start or end with spaces (e.g., " Sarah" or "Jack "). Apostrophes should be used correctly: They should not have spaces before them (e.g., "O' Connor" is incorrect; "O'Connor" is correct). Hyphens should be used correctly: They should only be used to separate parts of a name, not appear at the start, end, or in double form.
