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。

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

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())
或许需要。 如果你特别想说的话,可使用:
foreach (var propInfo in fields) {
if (propInfo.GetCustomAttributes(typeof(TestAttribute), false).Count() > 0) {
// Do some stuff...
}
}
或者,如果你真的需要,就能够做到:
var testAttributes = fields.Where(x => x.GetCustomAttributes(typeof(TestAttribute), false).Count() > 0);
