bool>>反转Expression<Func<T的正确方法

public class ExpressionReverser : ExpressionVisitor
{
    protected override Expression VisitUnary(UnaryExpression node)
    {
        if (node.NodeType == ExpressionType.Not)
        {
            return node.Operand;
        }
        return base.VisitUnary(node);
    }

    protected override Expression VisitBinary(BinaryExpression node)
    {
        if (node.NodeType == ExpressionType.AndAlso || node.NodeType == ExpressionType.OrElse)
        {
            return Expression.MakeBinary(
                node.NodeType == ExpressionType.AndAlso ? ExpressionType.OrElse : ExpressionType.AndAlso,
                Visit(node.Left),
                Visit(node.Right)
            );
        }
        return base.VisitBinary(node);
    }
}

public class Program
{
    public static void Main()
    {
        Expression<Func<bool, bool, bool>> expression = (a, b) => a && b;

        Console.WriteLine("原始表达式：");
        Console.WriteLine(expression);

        var reversedExpression = (Expression<Func<bool, bool, bool>>)new ExpressionReverser().Visit(expression);

        Console.WriteLine("反转后的表达式：");
        Console.WriteLine(reversedExpression);
    }
}

原始表达式：
(a, b) => (a AndAlso b)
反转后的表达式：
(a, b) => (a OrElse b)
