原标题:Get Func<T> and Expression<Func<T>> from single parameter?

I would like to get both the compiled Func(of boolean) and an Expression( of Func(of boolean)) using a single parameter. I don t intend to modify the expression tree. The only reason to take an Expression tree at all is so i can print out the code that is being executed.

void Assert(Expression<Func<bool>> assertionExpression) {
    if (!assertionExpression.Compile()()) 
    { 
        throw new AssertFailedException(assertionExpression.ToString()); 
    }
}
