[<System.Security.SecurityCritical>]
static member GetRuntimeInterfaceAsIntPtr : Guid * Guid -> nativeint
Public Shared Function GetRuntimeInterfaceAsIntPtr (clsid As Guid, riid As Guid) As IntPtr

参数

clsid
Guid

所需类的标识符。

riid
Guid

所需接口的标识符。

返回

IntPtr

nativeint

指向所请求接口的非托管指针。

属性
ObsoleteAttribute ComVisibleAttribute SecurityCriticalAttribute

例外

COMException

IUnknown::QueryInterface 失败。

PlatformNotSupportedException

注解

下表显示了支持的 clsid 和 riid 组合。

clsid riid
CLSID_CorMetaDataDispenser IID_IMetaDataDispenser、IID_IMetaDataDispenserEx
CLSID_CorMetaDataDispenserRuntime IID_IMetaDataDispenser、IID_IMetaDataDispenserEx
CLSID_CorRuntimeHost IID_CorRuntimeHost
CLSID_CLRRuntimeHost IID_CLRRuntimeHost (对.NET Framework 4) 提供的公共语言运行时无效，IID_CLRRuntimeHost3
CLSID_TypeNameFactory IID_TypeNameFactory
CLSID_CLRStrongName IID_CLRStrongName

GetRuntimeInterfaceAsIntPtr 类似于 GetRuntimeInterfaceAsObject 方法。
