在运行时从c#中的条件字典验证实体属性

public class Entity
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Email { get; set; }
}

public class Program

    public static void Main(string[] args)
    {
        // 创建条件字典
        Dictionary<string, Func<object, bool>> validationRules = new Dictionary<string, Func<object, bool>>();
        validationRules.Add("Name", value => !string.IsNullOrEmpty((string)value));
        validationRules.Add("Age", value => (int)value >= 18 && (int)value <= 60);
        validationRules.Add("Email", value => ((string)value).Contains("@"));

        // 创建实体对象
        Entity entity = new Entity
        {
            Name = "John Doe",
            Age = 25,
            Email = "johndoe@example.com"
        };

        // 获取实体属性
        PropertyInfo[] properties = typeof(Entity).GetProperties();

        // 遍历属性列表
        foreach (PropertyInfo property in properties)
        {
            // 获取属性值
            object value = property.GetValue(entity);

            // 验证属性值
            if (validationRules.ContainsKey(property.Name))
            {
                bool isValid = validationRules[property.Name](value);
                Console.WriteLine($"{property.Name}: {(isValid ? "Valid" : "Invalid")}");
            }
        }
    }
