Marshal::GetObjectsForNativeVariants<T> Method (IntPtr, Int32)

Note: This API is now obsolete.

[Supported in the .NET Framework 4.5.1 and later versions]

Converts an array of COM VARIANTs to an array of a specified type.

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

[ObsoleteAttribute(L"GetObjectsForNativeVariants<T>(IntPtr, Int32) may be unavailable in future releases.")]
generic<typename T>
static array<T>^ GetObjectsForNativeVariants(
	IntPtr aSrcNativeVariant, 
	int cVars

Type Parameters


The type of the array to return.


Type: System::IntPtr

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

Type: System::Int32

The count of COM VARIANTs in aSrcNativeVariant.

Return Value

Type: array<T>
An array of T objects that corresponds to aSrcNativeVariant.


cVars is a negative number.

GetObjectsForNativeVariants<T>(IntPtr, Int32) returns an array of T that corresponds 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 returned array is 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.

.NET Framework

Supported in: 4.6, 4.5.1
