Method Description
HandWrittenExpression ( string expression ) : System

Represents a hand-written custom expression. May be a chunk of SQL, or may be something else relevant to the underlying data access layer. This is both a very powerful and very dangerous expression; it allows you to construct complicated logic, but you can easily pass invalid input (that doesn't parse), sloppy input (hard coded table / column names), or even evil input (sql injection). MAKE SURE to sanitize any user input that makes its way into this expression!
HandWrittenExpression ( string expression, IEnumerable parameters ) : System

Represents a hand-written custom expression. May be a chunk of SQL, or may be something else relevant to the underlying data access layer. This is both a very powerful and very dangerous expression; it allows you to construct complicated logic, but you can easily pass invalid input (that doesn't parse), sloppy input (hard coded table / column names), or even evil input (sql injection). MAKE SURE to sanitize any user input that makes its way into this expression!
Invert ( ) : IExpression

Since handwritten expressions are completely custom, there is no automatic way to invert them. Therefore this is not supported.
ToString ( ) : string
