如何在TEntity中动态查找有值的属性？

using System;
using System.Reflection;

public class TEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
    public DateTime CreatedAt { get; set; }
    // 其他属性...
}

public class Program
{
    public static void Main()
    {
        TEntity entity = new TEntity
        {
            Id = 1,
            Name = "John Doe",
            CreatedAt = DateTime.Now
        };

        PropertyInfo[] properties = typeof(TEntity).GetProperties();
        foreach (PropertyInfo property in properties)
        {
            object value = property.GetValue(entity);
            if (value != null)
            {
                Console.WriteLine($"Property: {property.Name}, Value: {value}");
            }
        }
    }
}
