C# 城堡动态代理don'；t将自定义属性写入代理

我有一个简单的单元测试来重现这种情况：

[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; }
}

---

改用

Attribute.GetCustomAttributes（…）

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