是否可以使用 Spring.Net 代理 COM 接口？
我正在尝试使用 Spring.NET 和 C# 为 COM 接口创建动态代理。我目前正在尝试使用代码，而不是配置文件。 我的代码类似于以下内容：
Type comInterfaceType = typeof(ICOMInterface);
ProxyFactory proxyFactory = new ProxyFactory();
proxyFactory.AddInterface(comInterfaceType);
proxyFactory.GetProxy();
它在 GetProxy() 调用时爆炸，但出现以下异常：
System.InvalidOperationException: The property with name ArraySubType can't be found
in the type System.Runtime.InteropServices.MarshalAsAttribute, but is present as
a named property on the attributeData
[System.Runtime.InteropServices.MarshalAsAttribute(
(System.Runtime.InteropServices.UnmanagedType)28, ArraySubType = 0, SizeParamIndex
= 0, SizeConst = 0, IidParameterIndex = 0, SafeArraySubType = 0)]
这根本不可能吗？我仍在使用 Spring.NET 1.1，这在较新的版本中可能吗（我们最终将很快转向该版本）？
更新：经过实验，在代理 Form 类时，我也遇到了同样的错误，但参数略有不同（即 UnmanagementType 44）。
I am trying to create a dynamic proxy using Spring.NET and C# for a COM interface. I am currently experimenting using code, not config files.
I have code similar to the following:
Type comInterfaceType = typeof(ICOMInterface);
ProxyFactory proxyFactory = new ProxyFactory();
proxyFactory.AddInterface(comInterfaceType);
proxyFactory.GetProxy();
It blows up at the GetProxy() call with the following exception:
System.InvalidOperationException: The property with name ArraySubType can't be found
in the type System.Runtime.InteropServices.MarshalAsAttribute, but is present as
a named property on the attributeData
[System.Runtime.InteropServices.MarshalAsAttribute(
(System.Runtime.InteropServices.UnmanagedType)28, ArraySubType = 0, SizeParamIndex
= 0, SizeConst = 0, IidParameterIndex = 0, SafeArraySubType = 0)]
Is this simply not possible? I am still using Spring.NET 1.1, is this possible in the newer versions (which we will finally be moving to soon)?
UPDATE: After experimenting, I got this same error with slightly different parameters (ie. UnmanagedType 44) when proxying the Form class as well.

这似乎是 Spring.NET 1.1 中为代理方法生成属性时出现的错误造成的：https://issues.springsource.org/browse/SPRNET-852?page=com.atlassian.streams.streams-jira-plugin% 3A活动流问题选项卡。我们有一个解决方案来测试迁移到最新的 Spring 版本，所以我在那里进行了测试。它起作用了。
It seems this was a result of a bug in Spring.NET 1.1 when generating attributes for proxied methods: https://issues.springsource.org/browse/SPRNET-852?page=com.atlassian.streams.streams-jira-plugin%3Aactivity-stream-issue-tab. We have a solution to test migrating to the latest Spring version, and so I tested this there. It worked.
