城堡动态代理不要将自定义属性写入代理

我有简单的单元测试来重现情况：

[Test]
public void Castle_Writes_Attribute_To_Proxy()
{
    var generator = new ProxyGenerator();
    var proxy = generator.CreateClassProxy<MyType>();

    var type = proxy.GetType();

    var prop = type.GetProperty("SomeProp");

    var attrs = prop.GetCustomAttributes(typeof(DescriptionAttribute), true);

    Assert.That(attrs.Length, Is.Not.EqualTo(0));
}

public class MyType
{
    [Description("some description here")]
    public virtual string SomeProp { get; set; }
}

测试失败,因为Castle动态代理未写入自定义属性,

是否可以将父属性写入生成的代理？

解：
使用Attribute.GetCustomAttributes(…)

var attrs = Attribute.GetCustomAttributes(prop, typeof(DescriptionAttribute));

解决方法:

请改用Attribute.GetCustomAttributes(…)the method you’re using doesn’t work on properties.
