后夏普。Sdk。代码模型。BindingException:无法获取反射对象

autocad-plugin postsharp dll c#

Antxx · 技术社区 · 7 年前

我正在开发一个autocad插件,我正在使用PostSharp OnMethodBoundaryAspect在插件引入的每个命令之前执行一些任务。我使用属性声明性地添加了方面。

[PSerializable]
[MulticastAttributeUsage(MulticastTargets.Method, TargetMemberAttributes = MulticastAttributes.Public)]
public class OnCommandBoundaryAspect : OnMethodBoundaryAspect {
    ...

}

然后在命令类中

[OnCommandBoundaryAspect]
public class AnnotationCommands {

    [CommandMethod("MY_ACAD_COMMAND")]
    public void MyCommand() {
        doStuff();
    }

}

在针对普通acad DLL(普通autocad安装附带的DLL)编译插件时,一切正常。我们还有autocad OEM产品,其中包含插件。现在,当使用autocad OEM DLL编译插件时,我得到 后夏普。Sdk。代码模型。绑定异常 ,请参见堆栈

我了解到,与autocad安装程序附带的DLL相比,autocad OEM DLL在某种程度上受到限制。

怎么回事?为什么postsharp试图在项目中反映引用的dll?有什么建议可以解决这个问题吗?

如果组件存在于GAC中,并且在构建之前尚未移除,则也可能发生此问题。诸如方法签名更改之类的重大更改可能会影响PostSharp目标,因为它期望来自您的源的一个签名,并在GAC中找到另一个。

从GAC文件夹中删除程序集以帮助消除此原因。

好的,我应该知道这一点,但我们在命令类和 LispFunctionAttribute 类型在autocad OEM DLL中不可用。

[LispFunction("GetProperties")]
public static ResultBuffer GetProperties(ResultBuffer args) {
   ....
}

排除postsharp中的方法修复了该问题。

如果可能的话,最好在异常中显示类型名

“PostSharp.Sdk.CodeModel.BindingException:无法获取反射 “xxxxx”的对象。dll“
