如何从lambda表达式中提取自定义属性值？

using System;
using System.Linq.Expressions;

public class MyClass
{
    public string MyProperty { get; set; }
}

public static class LambdaHelper
{
    public static string GetPropertyName<T>(Expression<Func<T, object>> expression)
    {
        MemberExpression memberExpression = null;

        if (expression.Body is UnaryExpression unaryExpression)
        {
            memberExpression = unaryExpression.Operand as MemberExpression;
        }
        else if (expression.Body is MemberExpression body)
        {
            memberExpression = body;
        }

        if (memberExpression == null)
        {
            throw new ArgumentException("Invalid lambda expression");
        }

        return memberExpression.Member.Name;
    }
}

public class Program
{
    public static void Main()
    {
        MyClass myObject = new MyClass { MyProperty = "Hello World" };

        string propertyName = LambdaHelper.GetPropertyName<MyClass>(x => x.MyProperty);

        Console.WriteLine(propertyName); // 输出 "MyProperty"
        Console.WriteLine(myObject.MyProperty); // 输出 "Hello World"
    }
}
