用C#编写WMI永久事件使用者 [英] Writing a WMI Permanent Event Consumer in C#

问题描述

嗨！

我想用C#创建一个自定义的永久事件使用者.自
System.Management还不支持此操作，我必须使用Com interop
为我的.net事件使用者引用IWBemUnboundObjectSink，并且
我的事件使用者的IWbemProviderInit + IWbemEventConsumerProvider
提供者. (我已在msdn上阅读此文档:
http://msdn.microsoft.com/zh-CN/library/aa393014%28VS.85%29.aspx)
我可以"ComImport"所需的接口并实现它们，但是当我将程序集注册为Com对象时，这些接口不会显示在类型库中.
这是代码:

[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
[TypeLibTypeAttribute(TypeLibTypeFlags.FRestricted)]
[GuidAttribute("E246107B-B06E-11D0-AD61-00C04FD8FDFF")]
[ComImport]
公共接口IWbemUnboundObjectSink
{
[PreserveSig]
int IndicateToConsumer(
[输入] [MarshalAs(UnmanagedType.Interface)] IWbemClassObject_DoNotMarshal pLogicalConsumer，
[In] Int32 lNumObjects，
[输入] [MarshalAs(UnmanagedType.Interface)] ref IWbemClassObject_DoNotMarshal apObjects);
}

[Guid("C6659361-1625-4746-931C-36014B14667A")]
[ProgId("Payvision.PermanentEventConsumer"))
[ClassInterface(ClassInterfaceType.None)]
[ComVisible(true)]
公共类PermanentEventConsumer:IWbemUnboundObjectSink
{
const int WBEM_S_NO_ERROR = 0;

公共PermanentEventConsumer()
{
}

public int IndicateToConsumer(
IWbemClassObject_DoNotMarshal pLogicalConsumer，
int lNumObjects，
ref IWbemClassObject_DoNotMarshal apObjects)
{
Microsoft.VisualBasic.Interaction.Beep();
返回WBEM_S_NO_ERROR;
}
}

I want to create a custom permanent event consumer in C#. Since
System.Management does not support this yet, I have to use Com interop
to reference IWBemUnboundObjectSink for my .net event consumer, and
IWbemProviderInit + IWbemEventConsumerProvider for my event consumer
provider. (I have read this doc on msdn:
http://msdn.microsoft.com/en-us/library/aa393014%28VS.85%29.aspx)
I could "ComImport" the needed interfaces and implement them, but when I register my assembly as a Com object, these interfaces do not show up in the type library.
Here is the code:

[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
[TypeLibTypeAttribute(TypeLibTypeFlags.FRestricted)]
[GuidAttribute("E246107B-B06E-11D0-AD61-00C04FD8FDFF")]
[ComImport]
public interface IWbemUnboundObjectSink
{
[PreserveSig]
int IndicateToConsumer(
[In][MarshalAs(UnmanagedType.Interface)] IWbemClassObject_DoNotMarshal pLogicalConsumer,
[In] Int32 lNumObjects,
[In][MarshalAs(UnmanagedType.Interface)] ref IWbemClassObject_DoNotMarshal apObjects);
}

[Guid("C6659361-1625-4746-931C-36014B14667A")]
[ProgId("Payvision.PermanentEventConsumer")]
[ClassInterface(ClassInterfaceType.None)]
[ComVisible(true)]
public class PermanentEventConsumer : IWbemUnboundObjectSink
{
const int WBEM_S_NO_ERROR = 0;

public PermanentEventConsumer()
{
}

public int IndicateToConsumer(
IWbemClassObject_DoNotMarshal pLogicalConsumer,
int lNumObjects,
ref IWbemClassObject_DoNotMarshal apObjects)
{
Microsoft.VisualBasic.Interaction.Beep();
return WBEM_S_NO_ERROR;
}
}

(我只粘贴了2个课程中的1个)

(I only pasted 1 of the 2 classes)

任何帮助将不胜感激.谢谢
