Public Shared Function GetObjectForNativeVariant (pSrcNativeVariant As IntPtr) As Object

参数

pSrcNativeVariant
IntPtr

nativeint

指向 COM VARIANT 的指针。

返回

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 。

类型参数

T

要将 COM VARIANT 转换为的类型。

参数

pSrcNativeVariant
IntPtr

nativeint

指向 COM VARIANT 的指针。

返回

T

一个与 pSrcNativeVariant 参数对应的指定类型的对象。

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<T>(IntPtr) 返回类型的 T 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<T>(IntPtr) 提供 的相反功能 GetNativeVariantForObject<T>(T, IntPtr)。
