Log4PostSharp 项目通过继承现成的（和工作的）自定义属性

需要通过继承现成的（和工作的）自定义属性来修改 Log4PostSharp 项目。它看起来与此类似：

  [AttributeUsage(
    AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Module | AttributeTargets.Struct,
    AllowMultiple = true,
    Inherited = false)]
  [MulticastAttributeUsage(
  MulticastTargets.InstanceConstructor | MulticastTargets.StaticConstructor | MulticastTargets.Method,
    AllowMultiple = true)]
#if SILVERLIGHT
  [RequirePostSharp("Log4PostSharp", "Log4PostSharp.Weaver.SilverlightLogTask")]
#else
  [RequirePostSharp("Log4PostSharp", "Log4PostSharp.Weaver.LogTask")]
  [Serializable]
#endif
  public sealed class LogWithExceptionAttribute : LogAttribute
  {
    public LogWithExceptionAttribute()
    {
      ExceptionLevel = LogLevel.Error;
    }

    ...
  }

这就是我选择注释一些单元测试代码的方式：

[LogWithException]
private void DoThrowException()
{
  throw new Exception("test exception");
}

想要尝试调试编译时过程，尝试从命令行编译但无法得到任何提示：

> msbuild Log4PostSharp.Test.csproj /p:PostSharpBuild=Diag /p:PostSharpTrace="AssemblyBinding;Project" /v:detailed

哪个是解决问题的正确方法？我想做的事情是错误的吗？

Need to modify Log4PostSharp project by inheriting from the ready-made (and working) custom attribute. It looks similar to this:

  [AttributeUsage(
    AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Module | AttributeTargets.Struct,
    AllowMultiple = true,
    Inherited = false)]
  [MulticastAttributeUsage(
  MulticastTargets.InstanceConstructor | MulticastTargets.StaticConstructor | MulticastTargets.Method,
    AllowMultiple = true)]
#if SILVERLIGHT
  [RequirePostSharp("Log4PostSharp", "Log4PostSharp.Weaver.SilverlightLogTask")]
#else
  [RequirePostSharp("Log4PostSharp", "Log4PostSharp.Weaver.LogTask")]
  [Serializable]
#endif
  public sealed class LogWithExceptionAttribute : LogAttribute
  {
    public LogWithExceptionAttribute()
    {
      ExceptionLevel = LogLevel.Error;
    }

    ...
  }

This is how I've chosen to annotate some unit-test code:

[LogWithException]
private void DoThrowException()
{
  throw new Exception("test exception");
}

Wanted to try to debug the compile-time process, tried to compile from the command line but couldn't get any hint:

> msbuild Log4PostSharp.Test.csproj /p:PostSharpBuild=Diag /p:PostSharpTrace="AssemblyBinding;Project" /v:detailed

Which is the right way to tackle the problem? What is the wrong thing I am trying to do?

在 Log4PostSharp.Weaver.LogTask::ProvideAdvice() 中，有以下行：var customAttributeEnumerator = customAttributeDictionaryTask.GetAnnotationsOfType(typeof(LogAttribute), true);。 GetAnnotationsOfType() 的第二个属性是 false，这意味着只应发现 LogAttribute 注释。将其更改为 true 会导致考虑 LogAttribute 的所有后代（包括我的 LogWithExceptionAttribute）。
