Public Shared Sub GetNativeVariantForObject (obj As Object, pDstNativeVariant As IntPtr)

参数

obj: Object

为其获取 COM VARIANT 的对象。

pDstNativeVariant: IntPtr
nativeint

一个指针，接收对应于 obj 参数的 VARIANT。

属性: ObsoleteAttribute SecurityCriticalAttribute SupportedOSPlatformAttribute

例外

ArgumentException

obj 参数是泛型类型的实例。

注解

参数 pDstNativeVariant 必须指向足够的内存来存储生成的 VARIANT。此外，此方法的实现在参数指向的原始内存pDstNativeVariant上调用 VariantInit 函数。
