是否可以使用 .NET 泛型类实现 COM 接口?
我有以下接口,我试图使 COM 可见。 当我尝试生成类型库时,它不喜欢我的实现类派生自泛型类这一事实。
是否可以使用泛型类作为 COM 实现类? (我知道我可以编写一个非通用包装器并将其导出到 COM,但这会添加另一个我宁愿不做的层。)
[ComVisible(true)]
public interface IMyClass
{
...
}
[ComVisible(true), ComDefaultInterface(typeof(IMyClass))]
[ClassInterface(ClassInterfaceType.None)]
public class MyClass : BaseClass<IMyClass>, IMyClass
{
...
}
错误消息:
Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.
I have the following interface which I'm trying to make COM-visible. When I try to generate the type-library it doesn't like the fact that my implementation class derives from a generic-class.
Is it possible to use a generic class as a COM implementation class?
(I know I could write a non-generic wrapper and export that to COM, but this adds another layer that I'd rather do without.)
[ComVisible(true)]
public interface IMyClass
{
...
}
[ComVisible(true), ComDefaultInterface(typeof(IMyClass))]
[ClassInterface(ClassInterfaceType.None)]
public class MyClass : BaseClass<IMyClass>, IMyClass
{
...
}

无法导出泛型类型和从泛型类型派生的类型。 在您的
MyClass
类型上设置ComVisible(false)
。 您需要创建一个非泛型类实现或仅使用该接口。Generic types and types that derive from a generic type cannot be exported. Set
ComVisible(false)
on yourMyClass
type. You'll need to either create a non-generic class implementation or use the interface only.
