如何从代码中检索数据注释？（以编程方式）

扩展方式：

public static T GetAttributeFrom<T>(this object instance, string propertyName) where T : Attribute{    var attrType = typeof(T);    var property = instance.GetType().GetProperty(propertyName);    return (T)property .GetCustomAttributes(attrType, false).First();}

码：

var name = player.GetAttributeFrom<DisplayAttribute>(nameof(player.PlayerDescription)).Name;var maxLength = player.GetAttributeFrom<MaxLengthAttribute>(nameof(player.PlayerName)).Length;
