c# - 如何通过反射获得 protected 内部方法

Question

public abstract class BaseAspectAttribute : Attribute
{    
    protected internal virtual void OnMethodBeforeExecuting(object args)
    {
        Console.WriteLine("Base Attribute OnMethodBeforeExecuting Work");
    }
}

public class LogAttribute : BaseAspectAttribute
{
    protected override void OnMethodBeforeExecuting(object args)
    {
        Console.WriteLine("Log Attribute OnMethodBeforeExecuting Work");
    }
}

我尝试在 LogAttribute 中获取方法 =>

object[] customAttributesOnMethod  = methodInfo.GetCustomAttributes(typeof (BaseAspectAttribute), true);
foreach (object attribute in customAttributesOnMethod)
{
    MethodInfo[] methodsInSelectedAttribute = attribute.GetType().GetMethods();
}

如何在 LogAttribute 中获取 protected 覆盖方法？

调用 GetMethods 的重载，它接受 BindingFlags。尝试这样的事情:

attribute.GetType().GetMethods(BindingFlags.Instance | BindingFlags.NonPublic);
