public static class Expression
The Expression type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | Any |
Returns the start of an expression that will evaluate if any elements
inside of an array match a given predicate
Usage: Expression.Any("x").In(Expression.Property("prop")).Satisfies(Expression.Variable("x").EqualTo(42)) |
| AnyAndEvery |
Returns the start of an expression that will evaluate the following:
1. The array is not empty (has "any" elements)
2. Every element in the array matches a given predicate ("every" element matches)
Usage: Expression.AnyAndEvery("x").In(Expression.Property("prop")).Satisfies(Expression.Variable("x").EqualTo(42)) |
| Every |
Returns the start of an expression that will evaluate if every element inside
of an array matches a given predicate (note: That means that an empty array will
return true because "all zero" elements match)
Usage: Expression.Every("x").In(Expression.Property("prop")).Satisfies(Expression.Variable("x").EqualTo(42)) |
