Marshal.GetObjectsForNativeVariants Method

Converts an array of COM VARIANTs to an array of objects.

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

[SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)]
public static Object[] GetObjectsForNativeVariants(
	IntPtr aSrcNativeVariant,
	int cVars
)

Parameters

aSrcNativeVariant
Type: System.IntPtr

An IntPtr containing the first element of an array of COM VARIANTs.

cVars
Type: System.Int32

The count of COM VARIANTs in aSrcNativeVariant.

Return Value

Type: System.Object[]
An object array corresponding to aSrcNativeVariant.

ExceptionCondition
ArgumentOutOfRangeException

cVars cannot be a negative number.

GetObjectsForNativeVariants returns an array of managed objects corresponding to a raw pointer to a C-style array of unmanaged VARIANT types. The interop marshaler 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 it is your responsibility to free them as appropriate.

NoteNote:

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
