Lambdas
- Provide delegates,
Expression<T>where T is not a delegate type Expression<T>where T is a delegate type.- ability to produce an object model for an expression:
Expression<Func<int, bool>> greaterThanZero = value => value > 0; - Beneath the hood
ParameterExpression valueParam = Expression.Parameter(typeof(int), "value");
ConstantExpression constantZero = Expression.Constant(0);
BinaryExpression comparison = Expression.GreaterThan(valueParam, constantZero);
Expression<Func<int, bool>> greaterThanZero = Expression.Lambda<Func<int, bool>>(comparison, valueParam);
