如何在c#的表达式相等中使用MethodInfo和lifttonull

using System;
using System.Linq.Expressions;
using System.Reflection;

class Program
{
    static void Main()
    {
        // 创建两个表达式
        Expression<Func<int, bool>> expression1 = x => x == 10;
        Expression<Func<int, bool>> expression2 = x => x == 20;

        // 获取表达式的MethodInfo
        MethodInfo methodInfo1 = ((MethodCallExpression)expression1.Body).Method;
        MethodInfo methodInfo2 = ((MethodCallExpression)expression2.Body).Method;

        // 使用MethodInfo进行相等比较
        bool isEqual = methodInfo1.Equals(methodInfo2);

        Console.WriteLine($"表达式相等比较结果：{isEqual}");

        // 使用LiftToNull进行相等比较
        Expression<Func<int?, bool>> liftedExpression1 = Expression.Lift(expression1);
        Expression<Func<int?, bool>> liftedExpression2 = Expression.Lift(expression2);

        bool isLiftedEqual = liftedExpression1.Equals(liftedExpression2);

        Console.WriteLine($"使用LiftToNull进行相等比较结果：{isLiftedEqual}");
    }
}
