问题描述
我有以下的接口,我试图使COM可见。当我尝试生成类型库不喜欢我的实现类从仿制类派生的事实。
是否有可能使用通用类作为一个COM实现类?(我知道我可以写一个非通用包装和出口,为的COM,但是这增加了另一层,我宁愿做没有。)
[标记有ComVisible特性(真)
公共接口IMyClass
{
...
}
[标记有ComVisible特性(真),ComDefaultInterface(typeof运算(IMyClass))]
[ClassInterface(ClassInterfaceType.None)
公共类MyClass的:BaseClass的< IMyClass>中IMyClass
{
...
}
错误消息:
的警告:类型库导出遇到类型派生 从一个普通的类,并没有被标记为 [ClassInterface(ClassInterfaceType.None)]。类接口不能 暴露于这种类型。考虑标记与型式 [ClassInterface(ClassInterfaceType.None) 和揭露显式接口作为默认界面 使用COM的ComDefaultInterface属性。
泛型类型和种类,从泛型类型派生不能出口。设置标记有ComVisible特性(假)
在 MyClass的
键入。你需要要么只能创建一个非泛型类实现或使用该接口。
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
{
...
}
Error message:
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.
Generic types and types that derive from a generic type cannot be exported. Set ComVisible(false)
on your MyClass
type. You'll need to either create a non-generic class implementation or use the interface only.
