Public Shared Function GetObjectsForNativeVariants (aSrcNativeVariant As IntPtr, cVars As Integer) As Object()

Parameters

aSrcNativeVariant
IntPtr

nativeint

A pointer to the first element of an array of COM VARIANTs.

cVars
Int32

The count of COM VARIANTs in aSrcNativeVariant.

Returns

Object[]

An object array that corresponds to aSrcNativeVariant.

Attributes
ObsoleteAttribute SecurityCriticalAttribute SupportedOSPlatformAttribute

Exceptions

ArgumentOutOfRangeException

cVars is a negative number.

Remarks

GetObjectsForNativeVariants returns an array of managed objects that corresponds to a raw pointer to a C-style array of unmanaged VARIANT types. The interopmarshaler performs the identical transformation when exposing a VARIANT type to managed code. The method returns an empty array when the cVars parameter is 0.

The object array (the return value) gets garbage collected as usual. The unmanaged input array or individual VARIANTs in the input array are not freed. Therefore it is your responsibility to free them as appropriate.

Returns

T[]
