注意

CustomQueryInterfaceMode and support for ICustomQueryInterface may be unavailable in future releases.

指示 GetComInterfaceForObject(Object, Type, CustomQueryInterfaceMode) 方法的 IUnknown::QueryInterface 调用是否可以使用 ICustomQueryInterface 接口。

public enum class CustomQueryInterfaceMode
[System.Obsolete("CustomQueryInterfaceMode and support for ICustomQueryInterface may be unavailable in future releases.")]
public enum CustomQueryInterfaceMode

[System.Serializable]
public enum CustomQueryInterfaceMode

字段

名称 值 说明
Allow 1

IUnknown::QueryInterface 方法调用可以使用 ICustomQueryInterface 接口。 使用此值时，GetComInterfaceForObject(Object, Type, CustomQueryInterfaceMode) 方法重载的功能与 GetComInterfaceForObject(Object, Type) 重载的功能类似。
Ignore 0

IUnknown::QueryInterface 方法调用应忽略 ICustomQueryInterface 接口。
