Dynamically building a expression object RRS feed

  • Question

  • Hello,

    I'm new to using Expressions in C#. I've four predicates. I need to dynamically build the expression object as:

    var myExpressObject = Predicate1 And !Predicate2 And !Predicate3 And 
    !Predicate4;
    I tried as following but don't know how to proceed further on this :

    Expression<Func<T, bool>> expObject = x => true;
    expObject = expObject.And((Expression<Func<T, bool>>)Predicate1);

    Thanks.
