获取.NET 3.5中的Lambda表达式中使用的属性名称

using System;

class Program
{
    static void Main()
    {
        // 创建一个Person对象
        Person person = new Person { Name = "John", Age = 30 };

        // 使用Lambda表达式获取属性名称
        string propertyName = GetPropertyName(() => person.Name);

        Console.WriteLine(propertyName); // 输出：Name
    }

    static string GetPropertyName<T>(System.Linq.Expressions.Expression<Func<T>> propertyExpression)
    {
        var memberExpression = propertyExpression.Body as System.Linq.Expressions.MemberExpression;
        var propertyName = memberExpression.Member.Name;
        return propertyName;
    }
}

class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}
