Public Shared Function GetObjectForNativeVariant (pSrcNativeVariant As IntPtr) As Object

參數

pSrcNativeVariant
IntPtr

nativeint

COM VARIANT 的指標。

傳回

Object

對應於 pSrcNativeVariant 參數的物件。

屬性
ObsoleteAttribute SecurityCriticalAttribute SupportedOSPlatformAttribute

例外狀況

InvalidOleVariantTypeException

pSrcNativeVariant 不是有效的 VARIANT 類型。

NotSupportedException

pSrcNativeVariant 有不受支援的類型。

備註

GetObjectForNativeVariant 會傳回 Managed 物件，對應至 Unmanaged VARIANT 類型的原始指標。 Interopmarshaler 會在向 Managed 程式碼公開 VARIANT 類型時執行相同的轉換。

GetObjectForNativeVariant 提供 的相反功能 Marshal.GetNativeVariantForObject 。

當 VARIANT 類型VT_ERROR時， GetObjectForNativeVariant 會傳回 型 Int32 別的物件，而不是 UInt32 。

類型參數

T

要將 COM VARIANT 轉換成的類型。

參數

pSrcNativeVariant
IntPtr

nativeint

COM VARIANT 的指標。

傳回

T

對應於 pSrcNativeVariant 參數、指定之類型的物件。

屬性

例外狀況

InvalidOleVariantTypeException

pSrcNativeVariant 不是有效的 VARIANT 類型。

NotSupportedException
