财产信息——有属性的财富
原标题:PropertyInfo - GetProperties with attributes

我试图为网络项目确定一种习俗归属。

我已经能够从我的班子那里获得所有财产,但现在我不知道如何过滤这些财产,只是获得一些特性的财产。

例如:

PropertyInfo[] fields = myClass.GetType().GetProperties();

这将归还我的所有财产。 但是,例如,如何利用诸如“测试Attribute”等特性来归还财产?

我已经对此进行了探讨,但经过几次努力解决这一问题之后,我决定在此提出。

最佳回答
fields.Where(pi => pi.GetCustomAttributes(typeof(TestAttribute), false).Length > 0)

问题回答

使用<代码>。 定义:

PropertyInfo[] fields = myClass.GetType().GetProperties()
    .Where(x => Attribute.IsDefined(x, typeof(TestAttribute), false))
    .ToArray();

你们可以使用

    .Any()

简化表述

    fields.Where(x => x.GetCustomAttributes(typeof(TestAttribute), false).Any())
