Lambda expressions and how to combine them?

Viewed 8392

How can I combine two lambda expressions into one using an OR ?

I have tried the following but merging them requires me to pass parameters into the Expression.Invoke calls, however I want the value passed into the new lambda to be passed onto each child-lambda..

Expression<Func<int, bool>> func1 = (x) => x > 5;
Expression<Func<int, bool>> func2 = (x) => x < 0;
//Combines the lambdas but result in runtime error saying I need to pass in arguments
//However I want the argument passed into each child lambda to be whatever is passed into the new main lambda
Expression<Func<int, bool>> lambda = Expression.Lambda<Func<int, bool>>(Expression.Or(Expression.Invoke(func1), Expression.Invoke(func2)));

 //The 9 should be passed into the new lambda and into both child lambdas
 bool tst = lambda.Compile().Invoke(9);

Any ideas how to combine two lambda expressions into one and have the arguments of the child lambdas be that of the parent ?
