Public Shared Function GetObjectForNativeVariant (pSrcNativeVariant As IntPtr) As Object

参数

pSrcNativeVariant: IntPtr
nativeint

指向 COM VARIANT 的指针。

Object

对应于 pSrcNativeVariant 参数的对象。

属性: ObsoleteAttribute SecurityCriticalAttribute SupportedOSPlatformAttribute

例外

InvalidOleVariantTypeException

pSrcNativeVariant 不是有效的 VARIANT 类型。

NotSupportedException

pSrcNativeVariant 包含不受支持的类型。

注解

GetObjectForNativeVariant 返回一个托管对象，该对象对应于指向非托管 VARIANT 类型的原始指针。向托管代码公开 VARIANT 类型时，互操作shaler 执行相同的转换。

GetObjectForNativeVariant 提供的相反功能 Marshal.GetNativeVariantForObject。

当 VARIANT 类型为 VT_ERROR 时， GetObjectForNativeVariant 返回类型 Int32 为的对象， UInt32而不是。
